Cambridge seems to be running a study for how new markings in “door zone” bike lanes can reduce the instances of dooring. (thanks John for the tip)
BICYCLE LANE STUDY UNDERWAY SUMMER/FALL 2011
This summer, the National Cooperative Highway Research Program (REF) is conducting a study
evaluating various ways of marking bicycle lanes; Cambridge and Chicago are the two cities being
used for the research, each being busy urban areas with many cyclists.
The study will be looking at various bike lane widths on streets with and without on-street parking. The
study sites in Cambridge are Massachusetts Avenue between Harvard and Porter Square and
Prospect Street between Hampshire Street and Broadway.
The study will evaluate the influence of bike lane widths on how motorists and bicyclists travel on the
road and the comfort level of both bicyclists and motorists under various conditions. The study will
also look at how markings may help diminish the risk of “dooring,” where motorists parking
suddenly open car doors into the path of travel of cyclists.
Most of the line markings that are being used are temporary, and city staff will use information from the
study to help determine the preferred solution for the long term.
As part of the study, researchers will be surveying motorists and cyclists about their experiences and
perceptions. There is no personal data gathered as part of that study and the responses are
completely anonymous. If you are stopped while traveling, we would appreciate your responding,
but if you do not want to, just say “no, thank you,” and there will be no pressure.
If you have questions about the study, please feel free to contact Cara Seiderman,
I am all for studies like this, if it turns out a simple addition, or editing of the current way bike lanes are painted could reduce this risk, hurray!
