when im driving, ive noticed that when traffic lights are green there are no cars that are available to go thru then when it changes to red thats when car arrive.
sso my idea to reduce traffic congestion and more road widening is the smart traffic light. using those machine that surveyor use to detect incoming traffic. it would calculate velocity of vehicles travelling. aside from solving congestion problems it would also deter exessive speed and safety would also improve. it would be mounted in the middle of an intersection and it would have a 360deg digital picture of what is coming and going.
