Waiting time to reduce at traffic signals at 31 junctions in Chennai

Adaptive signals and passenger information systems to reduce waiting time and improve traffic flow in Chennai.

With 31 junctions on important roads in the city set to get ‘adaptive signals’ this month, the waiting time of road-users is expected to reduce.

Adaptive signals calculate the waiting time by taking into account the number of vehicles on the stretch, among other factors.

The work to install such signals on stretches, including the Santhome High Road, is under way. Similarly, 532 bus shelters of the Greater Chennai Corporation (GCC) will get a passenger information system that will facilitate tracking of buses and their estimated arrival time. Its installation, as part of the Intelligent Transport System (ITS) being implemented by the Chennai Smart City, is expected to begin next month.

In a few months, passengers can obtain information on the estimated time of arrival of the buses at the bus shelters of the GCC.

“We have completed the pilot project of the Intelligent Transport System. For adaptive signals, digging work has been taken up at the junctions on Valluvar Kottam High Road, Dr. Nair Road and other stretches. Work is under way on the Rajaji Salai,” said an official.

The GCC is expected to allow digging at more junctions for the project, after the northeast monsoon.

Work to install ‘traffic incident’ detection systems at 16 locations, and ‘automatic vehicle classifiers and counters’ at three locations are under way.
