Cool scoop from Cyclelicio.us: East Bay City Experiments with traffic light radar detection for bicycles.
Part of me wants to say that radar detection for bikes at intersections seems like readying the cherries for your sundae when maybe you should see about getting a bowl for the ice cream. You know, practical infrastructure: the bike lanes, separated bikeways, and bike parking playing the metaphorical bowl.
The other part of me knows a good thing when I see it. Acknowledging that bikes have a right to be on the road by incorporating them into the system hardware--yes, good, and hopefully this has the positive feedback effect (once/if the Pleasanton project is scaled up) of mainstreaming bike culture, and encouraging new users.
