Late last week Auckland Transport provided me with some fascinating stats related that broke down rail patronage results by station. The data is for the previous financial year -so from 1 July 2013 to 30 June 2014 – and covers 10.05 million trips out of the 11.44 million that took place. The difference between the two figures is primarily made up of special event patronage and legacy tickets still in use such as child monthly passes. Perhaps the best thing about the data though is that for the first time we can see how many people travelled from each station to each other station on the network. Getting this kind of information is one of the reasons that having customers not just tag on but also tag off with HOP is so useful.
The last time we had some station specific data was back in May which showed monthly patronage from July 13 to March 14 (although it was missing August)
In this post I’m just going to scratch the surface of what insights the data provides so please feel free to dig deeper into it and it would be great to see what kind of interesting visualisations you can come up with (and if you do please share them on here first).
To start with here is a map Kent has put together showing all boardings by station.
The data behind that is in the table below along with the number of people alighting at each station. There are a couple of things I notice straight away from the data.
- There are a hell of a lot of people not tagging off with 5.5% failing to do so. Of course we don’t know where this is happening but I would assume that apart from Britomart and Newmarket which have gates, that it’s fairly proportionate across the network.
- There has been a big surge in use of Henderson. In all previous figures that we’ve seen including the ones up to March this year Henderson has been around 8th to 11th busiest station based on the number of boardings and was 11th in that earlier data. It has now shot up to become the 4th busiest station which is a massive jump and could be one of the big reasons behind the rise in patronage we’ve seen on the Western line. Interestingly it hasn’t had the same sort of increase in people alighting (unless they make up a lot of the unknowns).
- Manukau has been the biggest mover after Henderson which has gone from 34th at the end of March to 38th. Panmure is also continuing to climb the station rankings and I’ve heard suggestions that some month’s patronage has been more than double the same month in 2013.
- The bottom three stations are unchanged although the exact order has shifted slightly. All three combined make up just 0.9% of all patronage. We know Waitakere is set to close once the Western Line is electrified and AT in the past have suggested closing both Westfield and Te Mahia, both of which were being decided on at the AT Board meeting yesterday.
- Britomart dominates patronage but not as much as you would think. Trips to and from Britomart make up just 55% of all patronage which is less than most people would probably think.
The results get more interesting when you start to look at where people are travelling to and from. As an example for my local station – Sturges Rd – I can see just 37% of people boarding a train there go to Britomart.
The two graphs below show the boarding and alighting at each station on a trip towards Britomart (Newmarket boardings are not included).
In the Western Line graph below it highlights that for Western Line passengers, Grafton has now edged out Newmarket as the second most important destination. For the Western line just 40% of people onboard a train bound for Britomart travel all the way.
The profile of the Southern/Eastern lines is quite a bit different with Britomart dominating more and taking 67% of all the trips for trains heading towards the city.
It’s fantastic to final get this level of detail and I look forward to when we’ll be able to see it on a regular basis plus see it for at least the Busway stations too.
As mentioned above it would be neat to see what visualisations of the data you can come up with. The data is here.
