(Ed. Note: With the forthcoming release of the LADOT Bike Program SLM (Shared Lane Marking) Study, the LADOT Bike Blog would like to take you back to the summer of 2010 and share with you the methodology of our Sharrow study. Confused? Check out our Sharrows 101 post or our Sharrows Page.)
Over three weeks in late May and early June of 2010, LADOT Bike Blog took part in pre-installation studies for the LADOT Shared Lane Marking (Sharrows) Study. The study documented the interactions between drivers and bicyclists when a bicyclist traveled at the position where Sharrows would later be installed. At the end of the summer, LADOT Bike Blog again took part in studying the interactions between drivers and bicyclists, this time with Sharrows in place. It all culminates with the release in the next few days of the LADOT Bicycle Program SLM report.
While the LADOT Bike Blog will have another write-up on the results of the report (and what it means for Los Angeles’ streets), we first wanted to give you a look at the goals, the methods, and the standards we used for the Sharrow study.
We don’t just want Sharrows, we want Sharrows the right way. We’re happy to give you a look at how we got there.
