Pattullo Bridge and Transit usage
Posted in Commentary on January 21st, 2009 by Sacha PeterThe reports of more people not using Skytrain after the closure of the Pattullo Bridge is not surprising, but it does demonstrate the collective intelligence of the public.
The simple reason for the lack of initial Skytrain usage is that anybody presently using the system already thinks that the Pattullo Bridge (when functional) will be impacting their commute time.
The Skytrain is an excellent system to get to any point within 400 meters of a station (the “5 minute brisk walk rule”); after this distance the utility of Skytrain diminishes significantly. The only exception is downtown Vancouver, where the entire downtown is fair game since it is a pain to get in and out of there.
The complex reason is that commuters are signaling they find it difficult to using public transit for off-Skytrain routes. For example, taking a bus will not improve your commute time since the bus system will still be encountering the increased traffic that was caused by the bridge closure.
To illustrate – let’s pretend you lived a 5 minute walk away from Surrey Central Station. Your workplace is in downtown New Westminster. Before the Pattullo Bridge closed, would you be taking Skytrain or car? Chances are you would be taking Skytrain. The bridge closure has no effect on you.
Let’s pretend you live in Langley City and work in downtown New Westminster. Since the bridge closure obviously affects you, would you park at King George and Skytrain it over? Or do you roll the dice and take the Port Mann? Or the Alex Fraser? Chances are you’re going to do one of those first, and then take the Skytrain if the other two decisions are too costly. This is assuming you don’t already do the “Park at King George” option. The information available suggests that a lot of people do this already.
The second day of the bridge closure should result in a lot more Skytrain usage than the first, as people feed this information into their “what’s the least amount of time for the least cost?” decision matrix.
One thing is sure – those people that work off of Skytrain routes are still more than likely to take their cars.
There is a subtle argument to be made that increasing the coverage of Sktyrain with linkages across the Canada/Expo/Millennium lines would increase ridership even further. For example, the network would be greatly enhanced by a link from Metrotown station to Brentwood along Willingdon – this has the strategic impact of servicing BCIT. The Canada Line would receive a lot more usage if there was a link from Richmond Centre to 22nd Street Station.
Although not apparently obvious you would see a lot more Skytrain usage in the event of a bridge closure if those two links were there – the benefit of highspeed transit is that the more nodes on the network you have, the more valuable the other nodes are. A lot of people are complaining that the Millennium Line is a failure, and although the placement was sub-optimal, it will benefit greatly from the upcoming Skytrain expansion.
