One more addition to the Denver list! If you know whom to call in Denver to get something done, you might also mention the lights that stay red until a car approaches doing below the speed limit (plus a few mph.) They may be called "rest on red." Those lights, like the loop actuated signals, don't detect bikes. A responsible cyclist, obeying the signal, ends up stopping at an empty intersection until a car approaches. The one on Montview around Elm would be a good example.)

(That light is a good example because, ironically, Montview is one of the small number of Denver streets with a bike lane. It may be the only bike lane in Denver that allows room for the "door zone." The new lanes at Stapleton don't. They allow no margin for an open door or even for a wide SUV. In addition, at least a couple of the recently designed and approved Stapleton lanes run riders directly into protruding curbs!)

The lights are good to slow cars down but indicative of Denver's approach to bikes, i.e. bikes belong on paths or sidewalks but not on the road. Speer Boulevard is the future of Denver bicycling: Bikes prohibited; use the sidewalk, press the pedestrian button, and show up once a year for Bike to Work day.
