Additional Commissioner of Police (Traffic) M. Ravi on Saturday launched localised Closed-Circuit Television (CCTV) network at 12 traffic junctions, most of the facilities on Anna Salai, in the city.

The facility equipped with a one-month back-up of footage would help police check traffic violations and issue notice to vehicle owners.

The CCTV will not be connected to traffic control room and will be managed locally.

According to Mr. Ravi, the World Bank-funded Centralised Traffic Control System had also become operational. Signals in the new system installed in 16 junctions, including the one near the new Assembly/Secretariat complex, would be managed automatically based on the density of vehicles.

“It has a sensor that will study the flow of vehicles and change the signals accordingly. Digital controller at the junctions will decide the direction of traffic flow based on vehicle density,” he said.

Mr. Ravi said efforts were on to introduce e-challan system by January.

Traffic police had registered 9.16 lakh cases, including 18,000 cases of drunk driving, this year and realised a fine of Rs.7.74 crore. Compared to 2009, the number of fatal road accidents and those involving serious injuries had come down, he said.
