Way more traffic in the Mission than in most areas of SF I know of except major streets such as Fell, Oak, and Lombard. But Mission Street itself stretches for miles and is 2 lanes in each direction. The accident rates by themselves seem high but I don't think they are out of the ordinary when compared to the traffic. Agreed.

My biggest complaint about the accident tracker in SF, is that the Bay Citizen designated certain streets and areas as "<a href="http://www.baycitizen.org/bikes/story/san-francisco-bike-accidents/" rel="nofollow">most dangerous</a>" based simply on a numeric count of accidents. They don't yet have the traffic data, so they are way ahead of themselves--and maybe a bit irresponsible--when they say, "most dangerous." Bingo.

Probably more bikers there than others parts so maybe the accidents are not statistically significant? I find Mission Street to be a very unsavory area and try and avoid it at all costs.

Although BikeArlington's site links to the National Bicycle and Pedestrian Documentation Project, which lists quarterly dates through 2012, it looks like Arlington is indeed moving to September counts only.

As you note, this does mean less demographic info. Arlington’s quarterly manual counts have been replaced by an annual one, I believe, as it now has three automated counters up and running.

Interesting that the new counters are not listed as recent or upcoming projects on the SFMTA site, but <a href="http://sf.streetsblog.org/2010/10/15/sfmta-begins-installing-more-bike-counters-around-the-city/" rel="nofollow">Streetsblog San Francisco</a> has information about where the counters are being installed. Manual counts definitely serve a purpose- you can't get data on demographics, helmet usage, etc. from an automatic counter- but for the purposes of the accident tracker, having this ridership data to overlay would be great. Does anyone know when/where the info will be posted? That’s good news.

This project is fairly new, so I'm not sure if any data from it has been made available.
