Want to Increase Cycling? Sharrows Won’t Cut It

In the last year, San Diegans have seen the increasing number of shared-lane markings, also called "sharrows." Sharrows are appearing everywhere: Adams Avenue, Park Boulevard, Broadway, El Cajon Boulevard, Grand Avenue, Voltaire Street, Chatsworth Boulevard, Hotel Circle South, Pacific Highway and more. However, these sharrows are being used as a cheap band-aid instead of implementing real change on our roadways that would increase the number of people riding their bicycle for transportation or recreation.

For starters, San Diego’s Bicycle Master Plan recommends sharrows on roadways that are too narrow for bike lanes. Sharrows are recommended on roads that have a minimum width of 14 feet. Bike lanes are recommended on roads that have a minimum of 15-17 feet. El Cajon Boulevard, for example, has three travel lanes in each direction – it has more than enough room for a bike lane.

So how can the City of San Diego increase the percentage of people who ride a bicycle? A recent report [pdf] from the Mineta Transportation Institute, an institute that was established by Congress to research "multimodal surface transportation policy and management issues," concluded that in order to attract a wide segment of the population, a bicycle network’s "most fundamental attribute should be low-stress connectivity, that is, providing routes between people’s origins and destinations that do not require cyclists to use links that exceed their tolerance for traffic stress, and that do not involve an undue level of detour."
