More Data Highlights
From fatalities to violations to the perennial question when it comes to bike collisions--whose fault was it?--we pulled out a few data points of particular interest.
All charts below are for the time period Jan. 2005 through Dec. 2009. Source: California Highway Patrol.
Our original Bike Accident Tracker showed that most San Francisco bike collisions were caused by bikers. This pattern holds true for the entire Bay Area. Cyclists were faulted for the majority of collisions in every county, reportedly causing 52% of them. Autos were cited in 34% of cases.
In all nine counties, men caused more bike accidents than women, whether they were the cyclist or the motorist in the situation. Bear in mind that gender was not noted in about 40 percent of the data; those accidents aren’t included.
Despite being a large (and potentially scary) city for a cyclist, San Francisco did not have the most fatalities over the five-year period. In fact, it didn’t even come in second. Santa Clara and Contra Costa had the highest number of fatalities, followed by San Mateo and Alameda. More details.
We took the top three overall violations and showed how many times they were cited in each county. In Alameda, most accidents were caused by a “wrong side of road” violation. In San Francisco, “right of way” violations were most frequent.
