The is a system used by many municipalities to auto change the traffic light to green for a siren. This saves time, avoids traffic ty-ups, and has proven to possibly save lives.
The system is used in Orlando and is called OptiCom, it is a 3 mmm co. |

I think the ones I saw (former volunteer) used an infrared transmitter mounted in the emergency vehicle to trigger a light status change, this did not always work because the cross traffic was not expecting the SHORT cycle and ran the red lights!!
