Welcome back to Sunday reading this long weekend.
We start this week with a borrowed slide explaining the way that the quality of your city’s Transit system controls the quality of your driving commute:
This explains what’s wrong with current expansion of SH16 and the completion of the Western Ring Route. The Transit part of this project is woefully inadequate: Intermittent bus lanes on the shoulder of the motorway are unlikely to lead to sufficiently fast or reliable bus travel times, this means the choice of taking the bus will probably not be attractive enough to tempt enough people away from driving on the newly widened motorway. This will lead to more induced driving and an increase in traffic congestion [which ironically will further slow those buses, because they are not on their own RoW]. Perhaps not immediately on the new parts of motorway itself, but certainly on local feeder roads and especially in the city and CMJ where the State Highways 1 and 16 and city exits all meet.
The biggest beneficiaries of high quality Rapid Transit are those who need or choose to drive. The better the alternative; the better your drive.
Staying with the value of Rapid Transit let’s head to Montréal where plans for a new layer of Rapid Transit has just been announced [in Lime Green below, with existing networks], which raises important issues around driverless technology:
Similar to Vancouver’s Canada Line, a system that CPDQ also has a financial stake in, trains will run every three to six minutes along the mainline and every six to 12 minutes on the three branch routes, including the train service from the airport to downtown. In contrast, the Deux-Montagnes commuter rail line is limited to every 20 to 30 minutes during rush hour and every hour outside of rush hour on weekdays.
But these high frequencies are only possible due to the nature of automation, which makes frequent train services significantly more economically feasible to operate. If there is a surge in demand, operators can easily and quickly increase frequency by deploying more trains by switching the controls at the operations centre.
With driverless technology, the operating costs are markedly lower than systems that require drivers and it has the potential to attract more ridership given that frequent services and superior reliability increase the utility of a transit system. Knowing that a train or bus will come soon, a transit service with a high frequency means transit users do not have to worry about service schedules. This reduces waiting times and connection times between transit services.
We really need to have a Transport Minister and Ministry just as excited about the opportunities for these technologies in the PT space as they are about them for private vehicles, the value is huge and the technology proven. SkyTrain in Vancouver has been driverless since 1985, carries 117m pax pa, and has run at an operating surplus every year since 2001.
Staying in Canada, here is how Montréal can have such ambitious city-building plans, central government is chipping in:

The new Canadian government is shifting investment to sustainable and social assets, away from Carbon intensive assets likely to become a burden on future citizens, and away from the failed ideology of austerity:
Investing in infrastructure creates good, well-paying jobs that can help the middle class grow and prosper today. And by making it easier to move people and products, well-planned infrastructure can deliver sustained economic growth for years to come.
At the same time, new challenges have emerged that make the need for investment more acute: things like the rapid growth of Canada’s cities, climate change, and threats to our water and land.
Congestion in Canadian communities makes life more difficult for busy families, and has a negative effect on our economy—when businesses can’t get their goods to market, it undermines growth.
A changing climate is also hard on communities. From floodways to power grids, investments are needed to make sure Canada’s communities remain safe and resilient places to live.
Investing in infrastructure is not just about creating good jobs and economic growth. It’s also about building communities that Canadians are proud to call home.
With historic investments in public transit, green infrastructure and social infrastructure, Budget 2016 will take advantage of historically low interest rates to renew Canada’s infrastructure and improve the quality of life for all Canadians.
In Budget 2016, the Government will implement an historic plan to invest more than $120 billion in infrastructure over 10 years, to better meet the needs of Canadians and better position Canada’s economy for the future.
Frankly I expect this kind of approach to become orthodox this century. That is once we can shake the stultifying grip of last century’s habits and world view, and properly start to address the issues in front of us.
More on vehicle speed and safety, this time from Nate Silver’s 538:
Given the social and economic toll of speeding, one might assume that we set speed limits with careful calculations aimed at maximizing safety. But that’s not exactly how it works, and a history of questionable applications of data is partly to blame.
Roads are planned according to a concept known as design speed, basically the speed vehicles are expected to travel.3 Engineers often apply the 85th percentile rule to a similar road to arrive at the design speed for the proposed road. It might make sense, then, that the design speed would become the speed limit. However, in practice, the design speed is often used to determine the minimum speed of safe travel on a road.
Confused? So was I. Norman Garrick, a professor of engineering at the University of Connecticut, explained how this works using the example of a commercial office building.
“It’s completely unacceptable for someone to die in a plane crash or an elevator,” he said. “We should expect the same of cars.”
And for some local flavour via Stuff: Drivers not coping with Christchurch’s new central city 30kph limit:
Acting Senior Sergeant John Hamilton said police spent 90 minutes on Friday to see if drivers were abiding by the new limits. Stuff witnessed about 10 drivers being pulled over for speeding on the corner of Montreal and Cashel streets within 30 minutes, including two Christchurch City Council staff.
Hamilton said most of the drivers ticketed were driving between 50kmh and 60kmh, with one motorist spotted driving 65kmh.
Now I have some sympathy with these drivers for the simple reason that the both street [see above] and vehicle design mean that to stay below 30kph in anything other than congested traffic takes a huge amount of attention and control. You might argue that we should be attentive and ‘in control’ whenever we are driving, and of course that’s true, but the fact is that most operation of the vehicle for anyone but learner drivers is a subconscious act, and in fact needs to be as we should be focussing on the environment and not constantly checking the speedo. But of course, in truth, half our minds are really elsewhere, on other things when we drive; we do it on a kind of human autopilot. So if we want drivers to keep to safer slow speeds in cities, or around schools, or wherever, we really need to change the physical environment to forcibly slow the ‘natural’ speed of those places.
As for the cars themselves, well that’s a lost cause, even the simplest little car is way overpowered and torquey for these environments: they just want to get up to highway speed and stay there. Perhaps these slow streets won’t really work until those law abiding pendants the bot-cars are ponderously pootling us around…? Note these drivers weren’t just breaking the 30kph limit they were all also breaking the old 50kph one!

Below a very interesting chart showing population change in London. I like that it has a name, and a good one, for the cycle we are clearly in now: City Renaissance and that it dates its beginning unambiguously to the early 1990s:
Note also that London’s population growth in this City Renaissance period has decidedly been both up and out, not just up. The rest of the paper, City Villages, PDF, from the Institute for Public Policy Research is very interesting too and relevant to Auckland’s situation. Basically the housing supply problem can be pretty clearly matched to the abandonment of public housing construction under neoliberalism, same as in NZ. Despite population growth, State and Council dwelling numbers have been falling not growing in recent decades:
And lastly, something from the energy transition department. Luís de Souza is a scientist from Portugal who is always worth reading on energy supply, especially for anyone interested in the longer term trends than the noise of the trader market as reported in the MSM. Here he is calling 2015 as the year of Peak Oil:
Titling the last press review of 2015 I asked if that had been the year petroleum peaked. The question mark was not just a precaution, the uncertainty was really there. Five months later the reported world petroleum extraction rate is pretty much still were it was then. This is not a surprise, but the impact of two years of depressed prices is over due.
Nevertheless, during these five months of lethargy the information I gathered brings me considerably closer to remove the question mark from the sentence and acknowledge that a long term decline is settling in. Understanding the present petroleum market as a feature of the supply destruction – demand destruction cycle makes this case clear.
So happy Birthday Queen Victoria [yes it’s actually her birthday], and happy reading…
