An article in the Herald on Sunday by academic and so-called resilience expert Dr Bridgette Sullivan-Taylor really raised some questions for me:
You might be reading this in an Albany cafe or a Wellington hair salon. You might be in the Sylvia Park food court, a Riccarton outlet complex, a Westgate supermarket, waiting to bungy-jump off a bridge or even at the airport.
It has probably already occurred to you that, while doing these activities, you could be placing your life in the hands of terrorists.
Questions such as:
And also some more technical questions about how much we should be willing to pay for “insurance” against unlikely or unpredictable events. Dr Sullivan-Taylor continues:
Black swan extreme events — those that come as a surprise — have a major effect and are often inappropriately rationalised with the benefit of hindsight. The challenge is to be prepared for them…
Examples of this are the cyber threat to banks and other global systems from such things as Ed Snowden’s classified information leak from the National Security Agency over the past two years; Fonterra’s Chinese milk crisis that threatened our major primary market; and the Germanwings disaster a few weeks ago in which a suicidal pilot flew a plane with 150 people on it into the French Alps.
So basically, she strings together a small number of totally unrelated events into an argument that we’ve got to be prepared for the next low-probability event. In other words: the world’s a scary place, and you’ve got to be frightened wherever you go!
Dr Sullivan-Taylor argument seems to be that we have to be “resilient” to any possible threat, no matter how unlikely. That’s an interesting, if unrealistic, assumption that I want to revisit after looking at her recommendations for not getting victimised by terrorism at your local mall food court.
So how might this affect New Zealand consumers? Hardening or toughening soft targets could mean that if you are going to the mall, you might have your bag checked at the entrances, and there might be restrictions on how long you can stay in the carpark. Employees might require security passes, and purchases might be checked on leaving the mall.
If you’re going to the cinema, there could be more security screening, including bag-checking machines. You might see more CCTV or facial recognition software being used inside the mall and in carparks that are watching all your movements. Security or police staff might ask for proof of identification, carparks might be occasionally restricted directly under or on top of the mall, and we might see more information in the media informing customers about raised security threats at particular locations.
There are two problems with these recommendations.
The first is that there is almost no way that Dr Sullivan-Taylor’s recommendations would stand up to a cost-benefit analysis. For comparison, here’s a review of a recent paper on the costs and benefits of protecting airports from terrorist attack:
Mark Stewart and John Mueller are here to alert us about the security at our airports. They want to warn us that it is too good. Or, at least, there’s too much of it. Their new paper is titled “Cost-benefit analysis of airport security: Are airports too safe?” The answer, the authors say, is most likely yes…
Stewart and Mueller calculated the cost of traditional airport security measures and compared it against the risk of an airport attack, the cost of the damage an attack would cause (in lives and property), and the efficacy of particular security measures in preventing an attack. Their finding: “Many of the assessed security measures would only begin to be cost-effective if the current rate of attack at airports in the U.S., Europe, and the Asia-Pacific increases by a factor of 10-20.”
In other words, the benefit-cost ratio for measures to protect airports from attacks is in the range of 0.05 to 0.1. That’s shockingly low even by the standard set by the RoNS. Given that airports are more tempting and systemically important targets than shopping malls and tourist attractions, it’s likely that costly measures to secure everything will be even less worthwhile.
According to Mueller:
“What’s your chance of being killed by a terrorist if you’re American?” he says. “It’s now about one in 4 million per year. Maybe that’s enough, maybe that’s not enough. Some people might say we can save some money and make it one in 3.5 million. What I’m trying to do is just apply standard analytic techniques to the hazards of terrorism.”
If we assume that New Zealanders are equally at risk of terrorism as Americans – a pessimistic assumption, I hope – we’d expect one Kiwi to be killed by terrorism every year. We could probably save as many lives by upgrading half a dozen dangerous intersections or curves in the road as we could by totally preventing terrorism. In other words, the expected value of total “resilience” against terrorism is quite small, and dwarfed by other risks we face.
Professor Ramesh Thakur from the Australian National University made this point quite well in a Radio New Zealand report on the subject:
“Think of the attention that was given to the terrorist attack on Mumbai. Of course it was a serious incident. But, as I said, in terms of people who are killed on the roads in India and in India it is pedestrians and cyclists who are killed much more than people in the cars, or any other way you look at it, in terms of the real threats to people’s safety and security terrorism should rank way down in the scale.”
The second problem with Dr Sullivan-Taylor’s proposal is that the resulting cost, time, and hassle would dismember our urban life. Cities, by their very nature, concentrate people and bring them together in unpredictable ways. There have always been risks to doing so – consider the burden of disease in Victorian-era British cities or the impact of violent crime in mid-century American cities. Terrorism, or the perceived threat of terrorism, is just the latest high-profile risk.
People have chosen to accept a few risks from urban life because the benefits are far, far greater. Living around and interacting with other people gives you more choices about employment and more consumption options. It gives you better transport choices and more places to go. Frequent, incidental human contact makes us happier.
Putting a security checkpoint everywhere humans might gather together – from malls to the waterfront to buses to art galleries – will cost society much more than it will ever deliver in benefits. The added friction will make the economic life of our cities less efficient and productive and our social lives stultified and hesitant.
In short, Dr Sullivan-Taylor seems to be massively over-estimating the value of “resilience” and vastly under-estimating or ignoring the costs of her preferred solutions. We certainly shouldn’t ignore the risk of terrorism, but as with any other public policy issue, we need to address it in a cost-effective and considered way. Her sensationalised statements about the risk of terrorism at your neighbourhood cafe, and associated claims about the need to secure absolutely every public place, do not amount to a rational risk assessment.
Finally, while the Herald on Sunday never should have printed such an ill-considered take on a serious issue, it did raise the issue of how we value resilience against low-probability events in our cities and urban transport networks. How much should we pay for resilience? I’d like to say more on that topic, but it’ll have to wait for a future post…
The New Zealand Herald’s cover story last Friday was quite sensational: “Homeowners in Auckland’s fringe saving up to $50,000 a year“. But while the eye-grabbing headline was worthy of clickbait merchants like Buzzfeed, the underlying analysis was not so good.
Here’s the key point of the article:
Bayleys calculated the first-year mortgage repayment costs for different suburbs based on median house prices from the Real Estate Institute of New Zealand (REINZ) and the ANZ variable rate of 6.74 per cent.
It found the annual cost of servicing a mortgage for a median priced Orakei or Remuera home ($1.35 million) was $84,060 in the first year.
In Pukekohe, where the median price of a home is $500,000, the annual mortgage repayment in the first year would be $31,128.
Even factoring in the $4032 annual cost of commuting from Pukekohe to the CBD by train on the At Hop card system – as well as the $768 public transport cost from Orakei to the city – living in the southern suburb was about $50,000 cheaper.
This is not entirely wrong. Housing costs do tend to decline as you get further out from the centre, while average transport costs tend to increase. That’s exactly what I found in a research paper I wrote on the topic last year. But it’s not entirely correct, either. Bayleys and the Herald have made two elementary errors in their analysis.
First, they’ve chosen a misleading measure of housing costs. House prices aren’t a realistic measure of the true cost of living at a point in time, as they are influenced by a range of short-term and long-term factors. In particular, when you buy a home, you are actually buying three very different things:
In other words, looking only at house prices is like arbitrarily including the cost of Kiwisaver into your housing costs.
My intuition is that rental costs are a better indicator of housing costs. They’re certainly less volatile, as I found in a recent paper that I co-authored on the relationship between rents and prices in Auckland. One of the key findings in that paper was that rents were quite low relative to prices in inner-city and coastal suburbs. As the following maps shows, median rents are only around 1/3 to 1/2 of median mortgage repayments in Remuera:
It’s not as though data on rents isn’t available. The Ministry of Business, Innovation and Employment publishes quarterly data on average rents for new tenancies, broken down by suburb, dwelling type, and number of bedrooms. So let’s take a look at that data instead. According to MBIE’s data, the average weekly rent for a three-bedroom house was:
- $754 in Remuera (or $39,000 per annum)
- $406 in Pukekohe (or $21,000 per annum)
However, there were a number of cheaper options available in Remuera, and the inner suburbs in general. Going down to two bedrooms would reduce your rent by $9,000 per annum – a viable and attractive option for many households – and looking for flats or apartments would save even more money.
But basically, looking at the rental data shows that most of the cost of buying in Remuera is not related to housing costs per se – you’re actually buying the expectation of capital gains. The rent data shows that it’s still possible to save money on housing costs by living further out, but the magnitude of savings is far lower.
Which brings me to a second major flaw in the Herald’s analysis: They have only accounted for the monetary costs of commuting further into the city centre and completely excluded the value of people’s time. A quick look at AT’s journey planner shows that the train trip from Pukekohe to Britomart takes about 70 minutes, while a public transport trip from Remuera to Britomart takes 20-30 minutes depending upon whether you’re closer to the train station or a bus route.
In other words, the Herald has assumed that people don’t mind spending an extra 80-100 minutes commuting every day. They haven’t even tried to account for the cost of wasted time. Most researchers and transport economists disagree with this approach. Here, for example, is a discussion of the subject from Charles Montgomery’s great book The Happy City:
[University of Zurich economists] Stutzer and Frey found that a person with a one-hour commute has to earn 40 percent more money to be satisfied with life as someone who walks to the office. On the other hand, for a single person, exchanging a long commute for a short walk to work has the same effect on happiness as finding a new love…
Daniel Gilbert, Harvard psychologist and author of Stumbling on Happiness, explained the commuting paradox to me this way:
“Most good things and bad things become less good and bad over time as we adapt to them. However, it is much easier to adapt to things that stay constant than things that change. So we adapt quickly to the joy of a larger house because the house is exactly the same size every time we come in the front door. But we find it difficult to adapt to commuting by car, because every day is a slightly new form of misery, with different people honking at us, different intersections jammed with accidents, different problems with weather, and so on.”
In short, the Herald’s analysis has:
- Overstated the real magnitude of financial savings from living in Pukekohe vs Remuera by a factor of three – a comparison of rental data suggest that the financial savings are actually $16,000 per annum or less
- Ignored the non-monetary costs of commuting extremely long distances, which makes people miserable. All else being equal, people should be willing to pay more to live in the areas which have the best job accessibility.
My advice, if you are choosing where to live in Auckland, is to disregard the advice of real estate spruikers such as Bayleys and the Herald, and take a more objective and comprehensive look at the topic using the affordability.org.nz app developed by my co-worker Alex Raichev. The app provides information on a much broader range of factors, including the rents, the monetary and time cost of commuting, and the costs of car ownership. Here’s a sample:
And, as always, my advice to the Herald is to check the facts more comprehensively before committing this sort of thing to print.
There have been a couple of articles in the Herald in the last few days that are worth talking about.
On Friday there was the issue of faults with the new electric trains.
Auckland’s new electric trains are still being bugged by computer software and braking problems, which have brought engineers out from Spain in search of remedies.
The city’s transport authority disclosed this week it is trying to bring forward from August the completion of its rollout of its $400 million fleet of electric trains, after continuing disruptions from diesel breakdowns.
But it is not just the old trains that are causing trouble, leading to a reduction in punctuality on all the city’s railway lines except for the Onehunga branch.
Rail workers are concerned some of the new trains are having to be shut down for their on-board computers to be reset, and that a sophisticated new control system designed to prevent collisions “has a tendency to randomly apply” emergency brakes when passing certain signals.
One industry source said in a message received indirectly by the Herald this morning there had been breakdowns on the rail network causing disruption “every day” for the past three weeks.
The emergency braking problem caused chaotic scenes at Britomart and Newmarket stations in the morning commuter rush in December, when a driver’s unfamiliarity with the new system prompted him to disable several other systems on board his train, disrupting 15 other services.
Auckland Transport chief executive David Warburton told his board this week, in his monthly business report, that Siemens Spain had undertaken a two-week investigation in New Zealand and was “working to improve ETCS [European Train Control System] reliability.”
It seems there has been a number of issues that have arisen with the trains, as the also herald notes in the article there were issues with how restrictive the new signalling system was when the trains were first introduced and it seems further improvements are due. I’m aware there have also been issues with the power supply and with the doors, both of which have been fixed. The latest issues seems to include some gremlins in the traction systems – something I’m sure will be ironed out.
I guess for me the thing is that while this is very concerning and annoying, this isn’t uncommon when brand new systems are installed. Even in mature networks new machines or parts of the network will tend to have issues. As an example the new trains in Wellington had to be pulled from service a number of times over a few years due to issues that arose.
While the outcome for passengers tends to be the same – delays and frustration – that’s quite different from the issues with the aging diesel trains. As I understand it, for them there’s often a difficult decision between temporarily patching up issues and properly fixing them – which could be quite costly – when the trains will likely only be used for another month or two.
In effect we seem to have both fleets of trains (electric and diesel) at opposite sides of a bell curve. The electrics have a lot of faults but they are getting better and more reliable and it is likely that soon faults will become much rarer while on the other side the diesels are getting more and more unreliable and that in part is also be accelerated by their pending replacement. Unfortunately what isn’t changing is the poor communication when things go wrong. Perhaps what AT and Transdev need is some more transparency in the matter and to explain to the pubic exactly what is going wrong. If the public were more aware of what the issues being faced are then they might be more accepting of the situation. In lieu of that that faults are leaving people with bad experiences and driving people away from using trains.
The second piece was related to the property purchases for the City Rail Link.
Plans for Auckland Transport’s ambitious $2.4 billion City Rail Link project are gathering speed, as it secures more real estate along the route.
An AT spokeswoman said the council-controlled authority had now bought 58 of the 70 surface properties it needs, spending $85 million securing the route – a critical part of Auckland’s biggest transport project.
That means AT now controls 83 per cent of the properties it needs and the full-steam-ahead approach has seen big progress since last year.
The update indicated 23 new property purchases were concluded in the past nine months, as owners agree to sell their land and buildings for the rail route’s progress.
AT’s relatively rapid pace is a big advance from the middle of last year when it had only concluded 35 surface purchases and spent $35 million.
Some politicians have questioned why all the pricey real estate is being bought well before Government funding as AT closes deals on the properties along its 3.4km Britomart to Mt Eden route.
AT’s biggest sticking point appears to remain the valuable Mt Eden Life Church, a property which it has been negotiating on for some time: the spokeswoman said the purchase of that big property near the Mt Eden Station, between the bottom of Flower St and Mt Eden Rd, was yet to be concluded.
Part of that issue is finding the Christians a new property. The spokeswoman said that was very much part of the deal and that no sale would be concluded until it was resolved.
“The issue is finding an alternative site. Negotiations are under way,” she said of 95 Mt Eden Rd.
The church has a number of businesses and owns several properties to the north and south but that property is the heart of its church operation.
That seems like good progress and given the rise in land values Auckland has been seeing – especially in and around the city centre – it is probably a good thing that they are buying the property now and not waiting until the government commit funding by which time the costs would have likely increased dramatically. The biggest risk is that it’s quite possible that when the government do help fund the project they will ignore the property purchases and enabling works (cut and cover tunnel to Wyndham St) and only fund 50% of the remaining costs.
I’m not an expert on the Public Works Act but is it normal for a public organisation to have to find alternative sites for current occupants? I guess that’s likely the easiest thing instead of forcing a sale but seems like it could end up quite costly.
There’s been quite a few bits of development news in the last few days that are worth covering. The first is in Albany where an 800 apartment development called the Rose Garden apartments might finally give some hope that Albany won’t be a completely soulless auto dependant centre. The development located on what is currently empty grass land just to the north of the mall is only about 500m away from the Albany Busway station – although more on that shortly.
One of the things I really like about the development is that they are selling one to four bedroom apartments which gives plenty of options – although the price of these larger options will be key. A quick search online suggests most of the four bedroom apartments are around $800-850k (although some are higher or lower). I also like that it appears the development will create activation out to the street edges which is something that will hopefully become more useful as more of the empty space is developed. On the video about the development on the Herald the architects behind the plan talk about density done well and I hope this lives up to that.
Perhaps one of the most interesting things about the sales pitch is to do with transport. There isn’t a single mention of car parking anywhere or even the common “it’s only X minutes drive to the city/beach/airport”. Instead the only mention of transport is that the development is in walking distance to the mall, Massey University, Albany Stadium and the busway station. On the busway station, it does talk about the bus only being only a 20 minute trip to town.
With Albany park-and-ride bus station two minutes’ walk away, you can be in downtown Auckland in less than 20 minutes. But everything you need is even closer to home at the Rose Garden Apartments.
To me this discussion about transport is a positive sign of both how successful the busway has been in changing perceptions about public transport and how much the city is changing away from the drive everywhere mentality. Even though it was already needed it does once again highlight how important it is that the Busway itself is extended from Constellation Station to Albany – something that the government cut out of their motorway project works. I think it also highlights that Auckland Transport will need to work to fix the racetrack like roads around Albany to make it easier and safer for people to be able to walk or cycle to the station.
In other news the Herald have announced (on Twitter) that in November they will move from their long time home on Albert St to office in Victoria St. Their site was sold last year to developer Mansons and is a substantial space in the heart of the city. The timing of the herald moving out is interesting as that’s likely to be just before works start on the CRL in the area. We’ll be looking to see what’s proposed for the site however one thing I do hope that happens is a new lane through the middle linking into Mills Lane.
Lastly it’s also been announced that the foyer of the St James Theatre is to reopen soon.
The foyer of Auckland’s long-abandoned historic St James Theatre will soon re-open as a cafe.
Major seismic strengthening of the whole building was also planned and sophisticated base isolation units being considered.
Mike Gibbon, development director for property owner Relianz Holdings, and architect Paul Brown, this morning said that in a few weeks, St James’ foyer would re-open.
But re-opening of the precious theatre was some years away, they said.
This will hopefully also help to activate some more of Lorne St outside the Library which for too long has had a large blank wall.
Lorne St Shared Space
It’s also positive that already over half of the apartments planned have been sold however I do have big concerns about the carparking associated with it which will apparently open out to Lorne St.
Brian Leyland has written an op-ed in the herald that is so comically wrong it’s hard not to ignore. Every single one of the 13 paragraphs contains (often basic) factual errors or opinion masquerading as fact. So I thought I’d highlight some of them.
The railway tunnel will serve only a very small fraction of Auckland’s population and at a huge cost. Mayor Len Brown is determined to commit Auckland to building a hugely expensive railway tunnel even though no comprehensive independent and objective economic analysis has been made on the merits of the tunnel and whether or not letting the city spread and developing satellite centres would be better.
More than 70% of Auckland’s population are already within 3km – an easy 10 minute bike ride if we built some safe infrastructure to support it – of a train station. The major urban areas not near the rail network are the North Shore, North West, Hibiscus Coast, parts of the central isthmus, the airport and East Auckland. The latter of those would feed into the rail network via AMETI and the Panmure Station.
Independently reviewed economic analysis has occurred and the project has had more scrutiny than probably any other transport project in this country. If the governments RoNS were subjected to even half of what the CRL has been they would have been canned years ago. More on the spawl comment later in the post.
Auckland Council has neglected its obligation to investigate and evaluate all options. Given the enormous amount of expenditure involved, this amounts to a serious dereliction of duty.
The City Centre Future Access Study (CCFAS) did just this and involved the NZTA and Ministry of Transport with the MoT even noting that the modelling has probably undercooked the patronage projections.
Overseas research on 44 urban rail systems revealed that the average cost overrun was 45 per cent and the number of passengers was half the predicted number. Have the economics of the Auckland tunnel been tested against 45 per cent higher costs and half the passengers? If not, why not?
Cost over runs aren’t limited to rail as the graph below shows – although it seems our recent rail upgrades have been ok. In saying that we seem to have been much better with managing costs on larger projects – many of which are claimed to have come in on time and under budget which is likely due to the additional detailed work that occurs beforehand which is happening right now with the CRL.
As for patronage, we can look at local examples to see how well our projections have fared. For Britomart we passed the 2021 prediction for the number of people passing through the station in 2011 and given the growth we’ve seen since that time that will only be larger now.
We’re also on track to exceed the 2016 target set in the Rail Development Plan of 2006 of 15.7 million trips in 2016 despite a later start to electrification than envisioned.
The railway tunnel will serve only a very small fraction of Auckland’s population and at a huge cost. Right now, ratepayers subsidise 80 per cent of the cost of every train fare. If the tunnel costs blow out by 50 per cent it will need to recover at least $450 million in fares every year for capital repayment and operating expenses. If, as hoped, there are 20 million rail trips every year, they will need to recover $22.50 per rail trip. Most of this will be imposed on the ratepayers.
Train fares currently cover around 26% however that figure has been improving this year and will likely continue to do so as the new electric trains roll out and patronage continues to improve so dramatically. I also expect we might see some improvement from the middle of next year (from reduced costs) as a result of AT re-tendering the rail contract – which I understand there are a number of interested groups. I expect Auckland will move closer to Wellington in this result which achieves 56% farebox recovery on its trains.
Importantly one of the benefits of the CRL is that while it will cost to run the stations and more trains, the farebox recovery ratio should further improve – potentially as high as 80%.
I’m not sure where Bryan has his 20 million rail trips per year from – I presume he’s confusing the governments target with a patronage projection. We haven’t seen total patronage results of any recent modelling and the CCFAS only showed the impacts at peak times however some older estimates put total patronage eventually up around 50 million trips per year.
The council planners seem to be totally unaware of the imminent revolution in personal transport that will be brought about by self-guided cars, modern taxi systems, ride sharing and buses. By the time the tunnel is in operation self-guided cars that will allow twice the traffic density on roads and reduce accidents by 50 per cent or more will be available. Not long after it will be possible to call up a driverless taxi or minibus by cellphone to take you where you want to go. For those who think that this is the stuff of dreams, it is now possible to buy a car that, in a traffic jam, will follow the car ahead and every major car manufacturer is developing self-guided cars.
These technological advances, combined with telecommuting (working from home and using the internet to communicate) and smartphone-assisted car pooling will have a huge effect on commuting and the shape of future cities. The council should take its head out of the sand and get up to speed with this revolution.
We’ve talked about driverless cars quite a bit recently so won’t go into that too much other than to say the uptake of new vehicle technology has so far been incredibly slow. As for telecommuting – the percentage of people doing just that hasn’t really changed in well over a decade despite it being easier than ever to do so. In fact many large companies – especially tech companies have done the opposite as they have recognised the benefits of working closer together.
Unitary Plan Rant that could probably have a post of its own:
The Unitary Plan is based on a blind belief that it is wrong to let the city spread and intensification is the only option
The Unitary Plan concentrates development in the central isthmus, which is already crowded and includes the volcanic area. The council has ignored the lesson from Christchurch that you should not keep all your assets in one place.
Most of the isthmus has well-established high-density suburbs with good houses, trees, gardens and lawns that are environmentally friendly and support large populations of birds and bees. The Unitary Plan will demolish these suburbs and substitute blocks of flats that will increase demand for parking, roads, schools, power, water supply, drainage and the like. There will be serious environmental and social impacts. Expanding infrastructure in an established suburb is far more expensive and environmentally damaging than building new low-cost houses on greenfield developments.
The council’s objective is to ration land and artificially inflate land values so as to force people to demolish good houses and force them to build apartment buildings to spread the rates burden.
Perhaps Bryan would like to point out where in the unitary plan it forces people to bowl their houses and build apartments. For most of the isthmus such an activity is actually prohibited due to heritage, zoning, density and height restrictions. In fact the central isthmus is almost locked in amber by the Unitary Plan as it stands now, especially compared to somewhere like West Auckland.
Auckland can pour vast amounts of money into city centre development in the hope of getting enough passengers to justify a railway tunnel, or it can allow the city to spread and develop satellite centres so that people can live in affordable houses and work in the same area.
Before any action is taken on the Unitary Plan and the tunnel, ratepayers should demand that an independent and objective study is done on the social, environmental and economic benefits of allowing the city to spread, compared with intensification. Nothing is more important.
Again perhaps Bryan should look at what work has already happened, such as this report from 2010 on the social, environmental and economic benefits of different development options and for which the large sprawl based one came out worse on the vast majority of measures. Perhaps one of the funniest things I’ve heard is that the modelling on the CRL shows that the more sprawl that’s enabled – particularly in south Auckland – the higher the need for the CRL is as it means there are even more people trying to avoid long lines of congestion from the hinterland.
Overall given his history and given the inaccuracy of his piece I’m surprised the herald even ran it.
The other week, the NZ Herald printed a good article on seven secret cycleways in Auckland. We covered it in last week’s Sunday reading post, but I thought it was worth adding a few more words on the topic.
In the article, Elisabeth Easther writes about her rides on the following cycleways:
- The new Westhaven promenade in the city centre
- Wattle Downs Peninsula near Takanini
- Cascades Shared Path in Pakuranga
- Conifer Grove in Takanini
- Waikaraka, Mangere Bridge, and Penrose.
While the rides themselves sounded pretty good, it’s ironic to see that Elisabeth had to drive to the start of many of the cycleways. This illustrates a tricky problem: individual cycle projects are increasingly excellent, but connectivity into the local streets is usually lacking. This makes it hard to use them to get around, as it doesn’t feel safe to get off the cycleway, back onto the surrounding streets, and out to final destinations.
As always, it’s worth taking a look at specific examples. Here’s a map of the Cascades shared path in Pakuranga:
This path offers some advantages for people seeking to travel places on bikes. First of all, it’s entirely off-road and runs through a big green belt, which means that it’s safe from traffic and not choked with fumes. Its northern branch terminates at the shops in Highland Park, and it has tendrils out to surrounding residential communities – meaning that there are both origins and destinations within reach.
However, AT’s broader map of cycle facilities in east Auckland (found here) shows that there are still many gaps in cycle infrastructure in the surrounding areas:
For context, here’s the legend on the map, which shows that most of the streets that are colored in are not in fact very useful for people on bikes. Light blue means that streets theoretically have “space” for cyclists but no dedicated cycle lanes. Yellow means that there’s a bit less traffic on the road. Roads coloured white are probably totally inhospitable if you’re travelling by bike.
What this means in practice is that it’s difficult to get to many key destinations on bikes, even though there’s a cycleway running through the centre of Howick. There’s no connection to the Botany town centre, near the south of the map, or any facilities along the busy Pakuranga highway or connecting to the Panmure rail station.
Another example from the Herald article. Here’s the Onehunga to Mangere Bridge section of the Waikaraka cycleway. (AT also has a map of the extension up SH20 to Mount Roskill.)
Once again, there are some really good things about this. It provides an alternative, non-motorised route between Mangere and Onehunga, with potential connections elsewhere throughout the southern bits of the isthmus. However, the good news doesn’t yet extend far enough. Here’s AT’s broader cycle facility map for Mangere and the surrounding areas:
Again, this is problematic. While there are some on-street cycle lanes in the area, they don’t go anywhere near the Waikaraka cycleway. They lack physical barriers or safe hit posts to keep traffic out. As a result, it is quite difficult for people on bikes to safely travel to destinations like the Mangere town centre or Otahuhu rail station.
Here’s the bit north of the Manukau Harbour:
This is not great either. There are no cycle facilities for people who want to get directly to the Onehunga town centre or rail station, let alone to head further north on Manukau Road. And there are a number of gaps on the route to Sylvia Park. I know that not everyone wants to cycle to the mall to shop, but I’m sure that there are a lot of teenagers (or adults, for that matter) who would love the option to bike there to hang out with friends or go to the cinema.
What this shows is that there are many, many gaps in our cycle networks. We need to fill them to reap the benefits from a complete cycle network. It’s not like we lack the road space to do this – the light blue lines on AT’s maps show streets with enough space to add cycle lanes. But unless we get serious about joining up the network, we’ll be left with a bunch of well-designed cycleways that aren’t useful for many trips.
What cycle infrastructure is your neighbourhood missing?
Yesterday, the NZ Herald chose to celebrate Auckland’s 175th anniversary with an editorial celebrating the city’s motorways. It’s an extremely odd piece to read in the wake of a string of good editorials discussing shared spaces, new cycleways, and the light rail proposals.
It’s also sad that the paper’s editors chose not to highlight Auckland’s many other features that we can take pride in. No mention of the city’s preserved natural heritage – the beaches, the Waitakeres, the Hunuas, the maungas, and two harbours. No mention of its preserved urban heritage – the villas and shops of Ponsonby and Devonport. No mention of its humming, vibrant centre, which has been brought back to life by Britomart, waterfront redevelopment, and pedestrian spaces, or the many other places, like the multicultural night markets or the Otara markets, where Auckland happens.
Instead of celebrating Auckland’s glories, the Herald chooses to make a virtue of its dysfunctions:
Auckland’s landscape and coastal attractions made its sprawl as inevitable as its preference for cars over public transport.
This is total hogwash. The Herald is attempting to re-cast Auckland’s outward expansion as an inevitable process in an attempt to win today’s argument about how best to accommodate future growth. “Planners”, they contend, cannot and should not attempt to fight the tide of suburbanisation and road-building.
Unfortunately, their own account reveals that Auckland’s current shape – and dependence upon cars – was in fact a planned outcome, not a natural one.
Here is the Herald discussing how Auckland got its motorway network:
They would do their utmost also to stop the Ministry of Works planning motorways south and west of the city. The southern route extended well past the green fields of Ellerslie and the meatworks at Southdown. If the ministry was not careful its motorway would allow housing to cover the fine farming soils of the Manukau County, absorbing the small towns of Otahuhu and Papatoetoe on the Great South Rd.
There were even plans to put a motorway on a causeway across the Whau estuary to the Te Atatu peninsula which could change the shape of West Auckland, developing to that point along the western rail line at New Lynn, Glen Eden and Henderson.
That’s right: the motorways were planned by central government. They didn’t happen on their own. They happened as a result of political fiat and bureaucratic intervention that aimed to shape demand, rather than responding to it. We have taken a look at how planned the roads were in a number of posts over the years. The bottom line is that Auckland’s pre-1950s public transport system was popular and well-used – and it was dismembered by planners who didn’t believe that we should live that way.
What was true for motorways was also true for housing development. The government was heavily involved in planning and building Auckland’s suburban lifestyle through a major programme of state house construction on greenfield sites:
The Government was building big state housing projects at Otara and Mangere in the 1960s. Suburban development crossed the Tamaki inlet to Pakuranga by the end of the decade.
In light of these facts, it’s hard to figure out what to make of the Herald’s criticisms of “planning”. Their attitude seems to be that urban planners are bad… but motorway planners are good. In other words, plan away, but only if you are planning a society and a city that conforms to the editors’ preferences and prejudices.
Ultimately, the editorial only serves to reveal the Herald’s own myopia. When they say:
It has never been Auckland’s character to look back, or forwards for that matter.
They are not speaking for the many Aucklanders who have a keen sense of history… and who look forward optimistically to the future. They are simply admitting to their own lack of vision.
There’s a good editorial in the Herald today about how the shared spaces have been a success.
Big bold ideas that turn out badly receive plenty of critical attention, those that turn out well tend not to receive the attention they deserve.
A big bold idea for the movement of people and traffic in Auckland’s central business district is working so well that we already take it for granted.
Walking or driving slowly in some of the side streets we hardly notice that pedestrians and vehicles are mingling without a problem.
Yet five years ago when the former Auckland City Council’s urban design group manager, Ludo Campbell-Reid, suggested turning the narrow streets into “shared space”, the idea was daringly radical.
It stepped outside the endless debate between those who wanted to close the streets to traffic and the business owners who feared a loss of access for suppliers and customers. We could have both, said Mr Campbell-Reid.
By doing away with footpaths, kerbs and parking spaces and paving the whole corridor in a way that was inviting for pedestrians but not smooth for cars, the city could favour foot traffic without barring vehicles completely.
It was “pro-pedestrian but not anti-car”, he said. To those who feared it would cause confusion or worse when cars and walkers were on the same path, he said relax, people would work it out.
So they have. Drivers who need or want to use those streets go slowly when pedestrians are there and the pedestrians move out of their way with hardly a thought.
It works naturally, unremarkably. Like all good solutions it seems so obvious that it goes without saying.
I love the shared spaces and can’t wait for more to be developed but they aren’t perfect. I personally would like to see the spaces be less linear using trees and/or others solid objects to force drivers to be even more cautious.
Most drivers who do use them drive appropriately but still some don’t understand, this seems particularly the case with many courier drivers who show no regard to pedestrians and will fly past them at speed – some even telling people to “get off the road”. AT could probably do more work in this area to help educate drivers.
Yet despite these few incidents and as mentioned most interactions are positive and as far as I’m aware there hasn’t been anyone injured on a shared space yet – although as the editorial points out, when it does happen the naysayers will be out in force.
Even now, those who had the courage to introduce shared streets probably break out in a sweat at times when they consider that sooner or later an accident is likely to happen. They know that if ever someone is injured by an inattentive or angry driver in one of these streets, there will be those who decry them.
But they have been operating without a serious mishap for nearly four years.
They close out the piece perfectly, highlighting that Federal St is poor thanks to the copious car park access points and giving a big serve to High St which has a few retailers actively fighting to keep carparking (that’s likely primarily used by them not their customers)
Not everything has been a runaway success.
Federal St shows that shared space alone is not always enough to make a place pleasant. Despite popular dining spots, entrances to SkyCity’s hotels and car parks make the street uninviting.
It is not beyond question, however, that it could yet develop into something much more attractive.
Either way, shared space is an improvement on parked cars and “rat-run” traffic in narrow alleys. Elliott, Fort and O’Connell streets are particularly good.
When will High St wake up?
It’s great to see the Herald highlighting this although it would have also been great if they could have also highlighted that most of these shared spaces have been great for business too.
Auckland Transport have taken up an idea by Deputy Mayor Penny Hulse a few months ago and are marking out where the City Rail Link will go in a bid to raise awareness of the project, especially ahead of the enabling works which will be disruptive to a decent portion of the city.
Aucklanders using Britomart this morning found out exactly where their future journey could take them.
Bright red lines tracking across lower Queen Street don’t mark Santa’s planned path but instead show where the City Rail Link (CRL) tunnels will go when the project starts next year.
Adding a bit of festive spirit to the Britomart and QE11 Square, the painted lines mark the centre of each of the two tunnels that will be built from the Central Post Office, under Queen Street and the square before heading up Albert Street and eventually to Mt Eden.
Project director Chris Meale says with construction of the enabling works for the CRL only a year away, the red lines signal the approaching works.
“While there is a lot of work still to be done before then, the red lines will indicate to Aucklanders that the first stage of the City Rail Link is not far away.”
Deputy Mayor Penny Hulse says she’s excited that there is a visible representation of where the City Rail Link will take Auckland and she’s eagerly anticipating a start on the physical works.
Mr Meale says the works will change the face of the downtown area for about three years. When the works start, buses will be re-routed, Britomart’s entrance will be relocated to the east end and through traffic will be diverted from Albert Street to provide access for tunnel construction. An information programme is being prepared in the lead up to the work
“It’s just a matter of time before Aucklanders will be able to see progress on our city’s number one transport priority. Tenders for the detailed design have closed with award planned for February,” he said.
Here are a few photos from readers this morning.
And this one from our good friend Sudhvir Singh who Penny credits with the idea.
I grabbed these as I was passing through this afternoon. Good work AT, and Penny Hulse and Sudhvir. Sooooo many people pass through here. I did occur to me that lines showing the actual width of the tunnel might better than just the centre line? Anyone agree? [PR]:
While on the topic of the CRL, there was this letter to the editor in the Herald today.
Of course while the council may not have directly surveyed on the CRL it has come out on top after two local body elections and various plans and strategies that have been publicly consulted on such as the Auckland Plan, City Centre Master Plan etc. It is part of an integrated PT network and Aucklanders have overwhelmingly said in numerous polls that they more focus on PT and it has even had strong support in polling done by the AA. Finally while not a public survey on whether we should build it, the project also received strong support from the public in the designation process and even many who opposed specific elements such as construction noise stated they wanted the project built. It would have been good for Chris Meale to have pointed this out.
If the council conducted a formal survey on the project I’d be almost certain that people like the letter writer above would then just complain about the council spending money on a pointless survey.
Following the gridlock on the roads last Saturday, the NZ Herald published several perspectives on how Auckland should cope with disruption to its transport networks. Matt weighed in with an excellent piece on the need to build Auckland’s long-awaited rapid transit network, which would give people an alternative to congested roads. However, the Herald “counterbalanced” it with some arrant nonsense about the need for more motorways by University of Auckland associate professor (and prominent climate change denialist) Chris de Freitas.
I use the term “nonsense” for good reason. The article was rife with factual errors that undermined the points that it was trying to make. Let us count the mistakes.
One: Congestion does not cost the Auckland economy billions each year.
De Freitas contends that:
The cost to the region’s economy of traffic delays is estimated to be many billions of dollars a year, which does not include the mental anguish caused to frustrated and angry drivers.
He does not provide any citations for this figure. However, I am aware of the relevant research, including a 2013 NZTA research paper by Wallis and Lupton that found that a more realistic figure for the cost of congestion in Auckland was a mere $250 million:
Including all congestion cost components, we concluded that the costs of congestion in Auckland are approximately $1250 million per year when compared with free-flow conditions, or $250 million per year when compared with the network operating at capacity.
In other words, the only way we could achieve that hypothetical $1.25 billion saving in congestion costs would be to build a network far, far in excess of what is required to move vehicles. Furthermore, Wallis and Lupton’s estimates are derived using NZTA’s Economic Evaluation Manual procedures, which explicitly account for non-monetary values such as travel time and driver frustration. The actual financial costs of congestion are likely to be an order of magnitude lower – i.e. closer to $25-50 million. That’s just not a lot compared to Auckland’s regional GDP of $75 billion.
Two: Auckland is not adding a Dunedin worth of population every 3-4 years.
De Freitas asserts that:
Given that the region’s population continues to expand by the size of Dunedin every three to four years, the vulnerability to traffic snarl-ups will grow exponentially.
According to the most recent Census data, Dunedin has a population of roughly 120,000 people. Between 2001 and 2013, Auckland’s population increased by approximately 255,000 people, or roughly 21,000 people per year. For those who like numbers, that means one new Dunedin every six years, not every three years. De Freitas seems to think that Auckland is growing twice as fast as it actually is.
Furthermore, the Ministry of Transport’s Congestion Index shows that travel time delay actually fell by one-quarter between 2003 and 2013. This contradicts de Freitas’ claim that congestion will increase “exponentially” as population grows – why hasn’t it increased over the past decade?
Three: Rapid transit networks are well-suited for regions with natural choke-points.
De Freitas argues that geography is destiny, and that Auckland’s skinny shape makes it a natural for roads:
Public transport itself will not ease the region’s traffic crisis. Auckland’s geography, history and politics make it a unique case for infrastructure planning. Its long, thin shape led to the earliest transport routes developing along a narrow north-south axis. Strategic arterial roads followed this pattern.
He correctly observes that road networks become less efficient when they are forced through natural choke-points like harbours and portages. However, these choke-points actually make public transport more efficient, not less. Putting more cars on a single road causes congestion and makes that road less efficient, but putting more buses or trains on a single right-of-way increases efficiency by allowing them to share costly infrastructure.
Four: Auckland’s motorway network already has alternative routes.
De Freitas contends that the Auckland motorway network lacks redundancy:
The result is a highway system that is not yet part of a fully integrated network. It is linear with no alternative routes around major bottlenecks. Traffic that would want to bypass the city is forced through Spaghetti Junction, adding to the vulnerability of the system to gridlock.
He has apparently not noticed that NZTA has almost finished building a bypass of Spaghetti Junction at a massive cost of $3.6 billion – the Western Ring Route. Perhaps he hasn’t been out west in the last decade, but if he had he would have noticed the construction of SH18 and the Upper Harbour Bridge, major expansions of the SH16 causeway, and the in-progress construction of the Waterview Connection to link SH16 with SH20.
Do we have to cover the whole region in asphalt to satisfy the man?
Five: A major earthquake in Auckland is extremely unlikely.
De Freitas raises the spectre of a Christchurch-esque quake:
The region’s most strategic arterial roads are vulnerable during earthquakes. Older multi-span bridges and abutments along motorways such as around Spaghetti Junction would be most vulnerable to damage from ground liquefaction. Even minor damage to these would bring city traffic to a halt.
Now, I’m no geologist… but both of my parents are geophysicists who started out researching Auckland’s rocks. They do not believe that Auckland faces serious risks of earthquakes. Volcanoes are a stronger possibility, of course, but volcanic activity doesn’t cause soil liquefaction. Here is a map from the British Geological Survey of every major earthquake in New Zealand since 1843. Notice the total absence of any recorded earthquakes anywhere near Auckland. Unlike Christchurch, we are not close to NZ’s fault lines:
Six: More roads are not a good solution for disaster readiness.
De Freitas argues that more roads are needed to evacuate Auckland:
The vulnerability of a city is to a large extent a function of the adequacy of preparedness planning. How soon could Auckland be evacuated?
There is limited motorway access out of the isthmus that is the Auckland urban area, so there few alternative exits. Main feeder roads head for one major harbour crossing and easily become congested.
Some American cities that are vulnerable to regular natural disasters have tested the “more roads” approach to evacuation. So here is Houston, attempting to evacuate on one of its eighteen-lane freeways during Hurricane Katrina in 2005. Not a lot of people actually made it out of the city:
We could devote endless hectares of increasingly valuable land attempting to repeat the same solution that failed Houston. Or, if we think that natural disasters are a serious risk, we could invest in disaster preparedness and civil defense to ensure that the city’s residents will still have access to food, water, and health care services, regardless of what happens. That’s likely to be a much more practical, cost-effective solution.
Finally: The Herald needs to get better at fact-checking, or print a retraction.
While de Freitas’ article was printed in the op-ed page, that is no excuse for its blatant errors and omissions. Auckland only has one newspaper of record, and its credibility and usefulness to its readers is undermined when it prints this sort of gibberish.
