Area Traffic Control System in India
ATCS is a fairly a new concept in IndiaAfter Delhi, Pune is the second city in India to have an ATCS; and the first city to have an indigenous ATCS
– 63 junctions in Delhi is under SCOOT (imported from UK) and 38 junctions in Pune is under CoSiCoSt (developed by C-DAC)
– CoSiCoSt is being implemented in Jaipur on a pilot scale

What is ATCS?Area traffic control systems are traffic responsive systems that use data from vehicle detectors and optimize traffic signal settings to reduce vehicle delays and stops The system operates in a closed loop, evaluating the real time demand and properly updating network signal timings

Challenges in implementing ATCS on Indian roads
Traffic is not lane followingA vehicle entering the approach (upstream) on a particular lane need not maintain the same at the intersection Uncontrolled side roads and on-street parkingHigh mix of trafficObtaining a correct measure of traffic count is highly complex Data loss due to power failureNetwork failureAvailability of funds

Addressing the Challenges
C-DAC developed a Composite Signal Control Strategy (CoSiCoSt) for distributed network model that address all typical Indian road conditionsStrategies are built into the system to guard against network failure, power failure etc.Distributed control give high scalability. Phased implementation of the system is possible based on funds availability

Summary of these MoEsAverage travel speed increase in the range of 2% to 12% Reduction in average delay in the range of 11% to 30% Estimated annual fuel savings in the year 2006 due to implementation of ATCS is about Rs. 4.77 CroresEstimated annual time saving benefits in the year 2006 due to implementation of ATCS is about Rs. 0.83 Crores Total annual saving in the year 2006 due to implementation of ATCS on the 6 project corridors is about Rs. 5.60 Crores
Over all Increase in the Traffic Volume is 9.06%
