A traffic signal smart enough to calculate the number of cars at an intersection and decide which road needs to be cleared first in the quickest possible time will be tested at three locations in the Capital.

The Delhi Traffic Police has revived this automatic signal project,part of its ambitious intelligent traffic system that has been hanging fire for more than two years.

The pilot project will undergo real-time tests at crossroads in New Delhi district,in Southwest Delhi till the airport and in South Delhi,including Lodhi Road,Aurobindo Marg and areas near AIIMS,sources in the traffic police said.

“Technical difficulties such as lack of technology and density of traffic delayed this project. Hence,we decided to take it up in phases and see how it works. If we succeed,it will be expanded to other areas,” a senior Traffic officer said.

The pilot project will include all features of the intelligent traffic system,but in a smaller area.

It has synchronised traffic signal cycles. It will calculate the density of traffic and automatically turn on the green light

for the road with the highest number of vehicles.

“At the same time,if only one vehicle is waiting for the light to turn green,the signal will automatically give right of passage to that car. Similarly,a road stretch with more vehicles will get 60 seconds of green light instead of 30 seconds,” the officer said.

To achieve this,it has been decided to synchronise 100 signals at various intersections.

“There are 780 signals across the Capital. We have identified 80 signals in New Delhi and 20 in South Delhi to test the system,” the officer said.

The project will include CCTV surveillance,high-speed cameras,enforcement cameras and variable messaging service.

The last one will alert drivers to breakdowns of vehicles,suggest alternative routes and possible diversions.
