The traffic police have introduced adaptive signal lights at 35 intersections in the first phase of the project. Vehicle Actuated Adaptive Signals (VAAS) can detect traffic flow in real time and adjust the red or green lights accordingly.

“The camera-based sensors in VAAS visually measure the number of vehicles on the road and the waiting time will be adjusted automatically,” said R Hithendra, Additional Commissioner of Police (Traffic).

The signal cameras capture traffic density at junctions and transmit it to sensor lights. The cameras will also calculate the queue of vehicles and change the duration of the traffic lights accordingly. “Adaptive signals will reduce the need for manual intervention by police at traffic junctions and commuters will also benefit from the reduced wait at traffic signals,” he added.

The road with the heaviest traffic will be given priority over other lanes. This will ensure even distribution of traffic at signals.

The VAAS project is on trial on the outskirts of the city. Based on the results, the police will implement the second phase of the project at other signals.
