Traffic lights that detect bikes

Apparently, it is a question of adjusting the sensor properly, rather than requiring a different kind of sensor. The only extra cost would be if the jurisdiction chose to mark the “sweet spot” that a bicycle should aim for in order to trigger the signal.

I’m pretty sure there is an evil bike sensor on the light at the intersection of Yorktown Blvd and N. Harrison St (at the bottom of a hill).. The light always turns red when it senses a bike approaching so you cannot use any of the momentum from coming down the hill to help you up the next hill. The designer of this sensor must be the same person who put “bike routes” on the hilliest streets in North Arlington…

I think Arlington prefers to put in video detection instead of inductive loop detectors for cyclists, but I’m not 100% certain.

FWIW, my sources told me last night that the cost is negligible if they’re installing a new system (v. upgrading an existing system), and that there’s no good reason Arlington would not include bicycle detection whenever installing a new signal.
