How often is this done? Do they also detect if a bike is at the intersection? Will they eventually cycle the light even if nothing is detected (just in case the sensor is not working)?
They are at almost every intersection in my state. I’ve heard people in bikes complaining about having hard time getting detected sometimes. I suppose it depends on how the light is programmed if it has a max time before it cycles, but I’ve had to go through intersections on a red light because I waited minutes and it didn’t turn green.
