Startup Idea : iCamera to control Traffic movement

Pain: In the current traffic situation we find that it is not properly regulated resulting in chaotic situation leading to traffic jams. Solution: In most of the traffic Jams happening around the traffic lights, the observation is, the traffic lights going Red/ Green depends on the pre-programming for certain time limit. However I believe it would be better to have intelligent cameras which control the traffic lights based on traffic density (length & width of traffic in that Lane). This can also control the next traffic light by sending the signals, more the density longer the traffic light. The data thus collected can be used for long term planning (like under/ over pass creation to decongest the bottleneck), mid term planning (like creating a separate path for 2 wheelers) which can stream line the traffic flow
