Stoplights are not sensitive to traffic flows or to factors like people running red lights; smarter traffic signals? #technology
Stoplights still are insensitive to the traffic of coming cars, so even when one street is not very busy, the light can go on forever. Stoplights should be more sensitive to the traffic flowing through an intersection. As an addition to this, if people are running red light like crazy, the light should be able to detect it and delay the green for the other cars.
