Auckland’s journey to work data from the census was released yesterday by the council on their site www.censusauckland.co.nz. Journey to work is a useful metric but it does have some serious flaws in that as the name implies it’s only recording how people got to work whereas there are generally a lot of other trips at peak times, like to school. In Auckland for example tens of thousands of students enter the CBD each day to go to the Universities or other education providers and those students all have a big impact on transport networks. This can be quite important when looking at PT trends as students tend to be much stronger users of PT than other parts of the population.
I’ll go through the data and how it’s changed over time in the next few days but here are some images from the maps showing the results which in themselves are quite telling.
First up travel to work by car, truck, van or company bus. Unsurprisingly the lowest car use is in the areas surrounding the central city as well as the lower North Shore. Whenuapai West will stick out on many of the graphs which I assume is due to airforce staff having very localised trips. The area around Pakuranga/Howick/Botany really stands out as being quite car dependant which is unsurprising seeing as the PT network in that part of the city have been so poor.
Next we have trips by public bus. What I find most interesting – and completely unsurprising – is that the areas with the strongest bus usage also happen to be the same areas where the most bus priority and frequency exists. Of the dark blue areas, those that surround Dominion Rd happen to have the highest bus usage.
On to train and that is obviously focused primarily on the areas next to the rail network.
For cycling the highest use is once again focused on the inner suburbs and on those along Tamaki Dr
Like many of the other measurements walking to work is something primarily seen in the inner suburbs although there are some stronger patches in some of the suburban centres.
Lastly Other under which ferries sit and because of that it’s unsurprising to see the areas with ferry service stand out strongly.
As mentioned earlier I’ll be looking into the results in more detail in coming days however what is quite clear just from looking at these maps is that the areas with the higher quality PT, walking and cycling links also happen to be the ones with the lowest car usage. In other words giving people high quality alternatives will see more people choosing not to drive.
