What Hacker News says
3 sourcesI wish them the best! These sorts of data are extremely powerful for local governments and advocacy for safer and better-designed streets.
There’s been a big push in Pittsburgh for improved traffic safety around the University of Pittsburgh and CMU due to several recent cyclist and pedestrian deaths. I’m not affiliated with the city or any local advocacy organizations, but as a concerned cyclist with some programming chops, I figured I could put some numbers to the problem myself with video tracking [0]. This impromptu weekend hack has garnered way more attention than I ever expected [1]. Being able to see long-term behaviors would be even more powerful.
