Absolute rubbish. Change the "green lights", behind the jam/incident will slow the flow into the congested area. Making it easier to get relieve the congestion. This with the use of VMS, encourages people to take alternative routes. Also upstream from the incident long green times will help traffic get away from the congestion.

Guess what - it is complex, but computer system and good algorithm can handle complexity.

technically Transport for London..

Traffic Signals can be designed this way - it is called priority "Hurry Call" in the UK.

However, it is counter-initiative in that a crash change to the approach where the Emergency vehicle is heading may (for example) cause the middle of the junction to not clear - making it harder/long for the Blue light vehicle to get through and cause more congestion for subsequent emergency vehicles.
