No Car but Drive Alone to Work

by Cook, Cliff

I'm hoping someone can help me address this question from a colleague. He put together a table from the 2006-2008 ACS showing mode of journey to work by vehicles owned and came up with surprisingly large numbers who do not won a car yet drive alone to work. No doubt, there are a few people who fit this category but my guess is that this largely is the result of either people misunderstanding the question or some sort of coding problem. Here is an excerpt from his email ( the Cambridge here is Cambridge, Massachusetts): I'm looking at ACS data and specifically at cities and percent workers have no car available. From that I'm then looking to see how those workers get to work. The attached worksheet shows my work. What is strange is that it shows for Cambridge that 6.6% of people without a car available drove alone to work. The percent is similar to Boston. And NYC has 3.4% of workers with No vehicles available driving alone to work. So, the question is, how can someone without a vehicle drive to work alone? Do you have any ideas on this? It could be someone doesn't own a vehicle, but drives a friend's car to work. Or has no car of their own, but uses a company car to get to work. But seems like a high number for this. Can anyone shed any light on this?

Re: [CTPP] No Car but Drive Alone to Work

by Rob CASE

Based on the 2009 NHTS, the ACS result seems reasonable. In the 2009 NHTS (weighted results), 12% of persons in zero-vehicle households who travelled to work "last week", did so in a vehicle with one person in it (500k people out of 4,260k).
