Comment Re:PLEASE someone, hook these to a traffic light. (Score 1) 186
Yes we have that, but it's not good enough. The loops can't tell when a car is approching until it actually arrives in the intersection so the light still cycles reguarless of traffic patterns. A "smart" camera should be able to anticipate if the light needs to change at all and for how long. It might have a 5-second north/south green to let one or two cars through followed by a 5-min east/west green due to there being no north/south traffic.
