[…] LADOT Sharrows Study Report […]
Hi. Great work on the blog here. Thanks for giving me the link to the LA city study on sharrows.
I have been searching for a study like this because I commute, by bicycle, daily on 4th street, and I have been commuting on 4th for several years now. In my experience, the sharrows have not changed behaviors on 4th street for drivers or bicyclists.
Being a social scientist, I also have some experience in research and methodology, so I read the report with great interest. While useful and well-executed, I would really hope to find some research studies out there that are a bit more ambitious in terms of their potential for structural change. This study is essentially asking, can putting sharrows in hurt us in any way or make behavior worse? I would much rather see a study that examines how both driver and bicyclist behaviors can change.
In any case, take this with a grain of salt. I suppose I’m a bit frustrated after years of dealing with errant and sometimes aggressive drivers on 4th street, many of whom seem like they could care less about a sharrow that is sometimes placed in the very middle of their driving lane. I would actually have liked to have interviews with 4th street drivers before and after the sharrows, or today, for that matter.
