Metro’s reporting that their supported vanpools have increased by over 100 vans in the past year, to a total of 1,058 vanpools and vanshares.
I would imagine that the total number of people moved has increased even more: as the costs of driving increase, it follows that the size of existing vanpools would increase, especially since the inconvenience of setting up your own vanpool is larger than simply joining an existing one.
Given how many employees have commutes that are very poorly served by transit, vanpools are an important part of the system, and cheap because the labor is free. I was unaware that King County’s was the first such program in the nation. I’d be curious to know what burden these vanpools place on the park and ride system; it would make a lot of sense to make agreements with churches that aren’t near transit lines to allow parking there, freeing up more spaces for transit riders.
