The findings Alan noted have been consistent over time and are always a little disquieting to someone who happens on them and then loses some confidence in the data. I do think folk underestimate the extent to which car loaning goes on in some sociodemographic groups. Part of the reason those millennials don't own cars is because they are still driving mommy or daddy's car. Using extended family member, friends or neighbors vehicles is quite common in many areas. Yes it would be nice if we had data confirmation.

I suspect Alan's thoughts are somewhat correct, but it would sure be nice to back this up with examples from personal interview surveys (in-the-field intercepts or CATI approaches) where there was a "logic check" for occurrences where a person indicated they drove alone, but yet they previously answered a "vehicles in the household" question by saying none. So a well-done logic check might at least prompt the interviewer to ask for a clarification. I am, however, not aware of this actually being fielded. -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of ALANPISARSKI Sent: Thursday, July 23, 2015 9:51 AM To: ctpp-news(a)chrispy.net Subject: Re: [CTPP] Commuters Who Drive Alone but Do Have Access to a Vehicle This has been around too long to be explained by car2go or others like it but it may be adding to the numbers. We have often just attributed it to using friends' cars or uncle Harry's. some may interpret the census question which asks about household vehicles available as not pertaining to a company car. Depends how they interpret family or available. We have seen the rise in this and in "Other" with the Census unable to explain it or give greater info for us to interpret. We need a small study of "Other". I have interpreted Other to be, e.g., a school bus driver who brings the bus home-but it's not a household vehicle available.

He didn't explicitly say it was happening. You could probably talk with the car share company in Cambridge. I would think they would be interested in your situation. -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Cook, Cliff Sent: Thursday, July 23, 2015 9:10 AM To: <ctpp-news(a)chrispy.net> Subject: Re: [CTPP] Commuters Who Drive Alone but Do Have Access to a Vehicle Greta Was Nick Hill able to provide any numbers to back this up? We do have a robust car share network in Cambridge so that could be part of the answer. Cliff Sent from my iPhone wrote: Possibly these people use such a service to commute. On Behalf Of Cook, Cliff transportation planning program. An issue that has come up is that we are seeing a small but noticeable proportion of commuters who state they have 0 vehicles available but whose primary commute mode is driving alone. Aside from the obvious explanation of making a mistake when completing the ACS survey can anyone provide thoughts on how we might explain this anomaly?
