The new (2012) version of the California MUTCD has been released, and has the provision for Sharrows in it. I cannot claim to have fully read and understood the entire manual, but I was wondering what others experience with Sharrows has been.
I am a bicycle commuter, and most days, my commute takes me home on Bowers Ave, from Kifer to Cabrillo in Santa CLara. Between Chromite and Cabrillo, Bowers is equipped with sharrows. There is on street parking, and the sharrows are positioned to encourage cyclists to ride in the door zone, but beyond this, I find that I have more close passes in the section of road with Sharrows than on any other part of my commute. An example of a close pass (actually brushed by the car) can be seen in this youtube video: http://www.youtube.com/watch?v=wyf3nRhOUtg . Have there been any studies done comparing the safety of roads with Sharrows vs those with no 'improvements' at all? Are there others who have had more positive experiences on roads with Sharrows?
