How many times have you been sitting in traffic cussing out a traffic light that changed, with no other cars in the other intersection. It happens here in Hawaii “ALL THE TIME”. These idiot traffic engineers here have not a clue what a timed traffic light is.
When I lived in Guam I loved driving at night because all you had to do was flash your high beams at a RED light and it would change if no traffic was detected coming the other way. It was common to see cars start flashing their high beams when they were 500 ft away to try and get the lights to change quicker. Guam is a small place but has twice as many cars as people so traffic was always a problem so smart lights were appreciated.
Seems their has been some research on this front and municipalities would be smart to listen to what it being said. [Smart Mobs]
