Signal synchronisation to ease traffic woes in Bengaluru

In a possible solution to endless traffic snarls in the city, Bengaluru will soon witness signal synchronisation. This technique coupled with quality signalling and traffic light controllers that activate lights depending on the volume of traffic will facilitate free flow of traffic. Apart from the road to the airport between Rajbhavan and Hebbal, four other important routes that experience high volumes of traffic have been identified to pilot this project.

They are: the Old Airport Road from ASC Centre to Hope Farm Junction, MG Road to Silk Board via Vellara Junction, Dr Rajkumar Road entrance to Peenya, and Ulsoor to Devasandra via KR Puram.

Chief secretary Arvind Jadhav has been directed to set up a review committee at the Directorate of Urban Land Transport (DULT) level involving all stakeholders of city traffic movement. “This committee shall review all issues pertaining to traffic and urban transportation. The planning has to be housed by DULT, executed by BBMP and enforcement of traffic-related issues to be done by traffic police,” said Jadhav at the co-ordination meeting of the stakeholders recently. To ease the heavy pressure on city roads, RK Misra suggested that the traffic police plan signal synchronisation and quality signalling in five corridors on an experimental basis. “DULT, in association with Japan International Cooperation Agency, has prepared a master plan for the intelligent transportation system (ITS). This could be used as a pilot project on these five corridors,” he said.

Junctions along these corridors will first have to be embedded with sensors to introduce the synchronisation system. “Junctions equipped with cameras will capture data of traffic volumes on the different arms of a signal and turn a signal red or green accordingly,” an official said.

The project is likely to cost Rs 70 cr, so the government may go in for a loan. Centre for Development of Advanced Computing (C-DAC), Bharat Electronics Limited (BEL), Microsoft and Indian Institute of Science (IISc) are in talks with the state government over the project. Additional commissioner of traffic police R Hitendra says the paper work is ready, but the progress is being made cautiously.

“IISc is ready to conduct a study but not everyone is optimistic that the project will succeed. The government is yet to take a final call.” The reason the project is being eyed with suspicion is the high density of traffic in the city. Signal synchronisation, according to those in the know, works when the density ration is normal, or 1. “But with the density ratio as high as 2 on most roads in the city, the system is unlikely to click,” an expert revealed.
