AUTOMATED TRAFFIC SIGNAL CONTROLLER USING AT-89C51
ABSTRACT:-
In this project automated traffic signal controller using AT-89C51, which set the traffic signal counter value depending on the traffic rate in the road. Initially, the input image is background subtracted to extract the foreground objects. The foreground objects are tracked using snake algorithm. The tracked objects are then compared with the predefined templates. The count of number of vehicle is incremented as it encounters a matched object. Based on the count of vehicles, the value for the signal counter is set. In the mean while, the camera is rotated to 180 degrees to view the other side of the road and the same procedure is repeated. In most automated traffic signals the free left-turn condition is provided throughout the entire signal period, which poses difficulties to the pedestrians in crossing the road, especially when the traffic density is high. This controller allows the pedestrians to safely cross the road during
Certain periods.
