As Population is expanding day by day, so are the vehicles on the road. The road congestion is becoming a considerable problem especially in India. How much early I get up, I always miss my first class at college or sometimes I had reached at lunch break too. I see hundreds of vehicle standing and just wasting fuel because of the unoperated traffic lights. Is this the way of sustainable development ? Conventional methods are even better than the today's traffic light system. So I decided to make the system dynamic and more superior to eradicate the Delay waiting period at the intersections. Dynamic Timings of phase : Calculation of Traffic density of four phase intersection using image processing which is done on videos of vehicles that are captured using digital camera. We have chosen image processing for calculation of traffic density as cameras are very much cheaper than other devices such as sensors. According to the calculated density, optimum green ratio or we can say that allotment of green light is done in an efficient manner to reduce the delay of vehicles or indirectly the congestion of traffic.
