Bike Accident Tracker: Contra Costa Least Safe Place to Bike

Hola amigos, I know it's been a while since I rapped at ya, but I've been trying to figure out what my intentions and ambitions with this publication are, exactly.

In the meantime, a totally excellent example of public data sharing and professionally-managed crowd-sourced journalism: The Bay Citizen's Bike Accident Tracker. Maps, charts, data. Agent at fault, type of crash. Really great stuff.

Click to enlarge--and note the customized search/sort featers at left.

Aggregated results: Contra Costa County is the worst. Not for the total number of crashes, but for the percentages of bike commuters who are involved in accidents. From 2005 to 2009 there was an average of 288 accidents involving cars and bicycles in CC, or 11% of the roughly 2568 bike commuters.

San Francisco, though it posted far more accidents, also posted far more commuters--and only 4% of them were involved in crashes.

Premise

Suburban areas are automobile scale. This requires surfeits of space and asphalt, generating lower densities and further necessitating automobiles. The positive feedback (and resource consumption) loop goes on and on.

This blog is first and foremost about establishing that suburbs need to change, and deconstructing the assumption that such places cannot evolve toward more sustainable patterns. With smart retooling, suburbs can accommodate more diverse uses than their land-use lets on.

I'll explore suburban busing, biking, BARTing, walking, parking, building designing, retrofitting, greening, funding, and zoning, all with an eye toward rethinking the shape and function of the suburbs.
