Most of the road accidents occur due to traffic violation and over speeding. Running vehicle avoiding the traffic lights has become a major issue now a day. Observing traffic violation manually has become tedious and too complicated, on account of expanding the number of vehicles on the road.

To decrease the number of road accident we propose a system which controls the speed of vehicle consequently in any basic zone, without significant inconvenience to the driver.

A decision is taken by a controlling module in the vehicle and controls the speed appropriately.
