CDAC WiTraC - India's Wireless Traffic Control System Runs On Solar Power

CDAC has developed WiTraC - India's own wireless traffic control system that runs on solar power. The center for development of advance computing is globally known for the development of PARAM brand of Indian supercomputers. The technology was made available to private players by communications and information technology minister, Mr. Kapil Sibal. The overall cost of the project has been estimated to be about Rs. 14.75 crore. CDAC says that the system is quite power efficient and the solar panels would equip the system with 72 hours of backup time.


The WiTraC system is a vehicle actuated road traffic signal controller that takes the ownership of the signal lamps through wireless signals. The WiTraC system is ATCS aka Area Traffic Control System capable of operating independently or as a part of synchronised chain of controllers. Other features of WiTraC include remote monitoring and management of signal plans, GPS / Server based distributed time sync, pole mountable miniature architecture etc. There's a provision for a camera to keep an eye on the traffic conditions and monitors every vehicle. The camera itself can be monitored from a centralized control room.

The system has been developed under Intelligent Transportation System Endeavour (InTranSe), specially for Indian cities & traffic conditions. The project is expected to pan India; and has been funded by the Department Of Electronics & IT (DeitY), Ministry Of Communications & IT of India.

The system has already been installed in Pune by Trafitronics - company responsible for marketing of the unit.
