Kerala Road Fund Board (KRFB) has installed the country’s first vehicleactuated wirelesss traffic signal controller (Wi-TraC) at a busy junction in Thiruvananthapuram, the capital of India’s Kerala state.

Developed by 5951 C-DAC (Centre for Development of Advanced Computing), the premier R&D organization of the Department of Information Technology, and manufactured and installed by major Indian electronics corporation, 5952 Keltron, Wi-TraC has distinct features over conventional signals.  The camera in the system can detect vehicles and will change signals accordingly to prevent vehicles having to wait at a red light when there is no vehicle coming in another direction.

Since it is small and pole-mountable, the energy efficient Wi-TraC system does not occupy any space on the pavement. It has a GPS-enabled real-time clock (RTC) for distributed time-synchronisation.

The 32-bit microcontroller-based intelligent road traffic controller consists of a master controller and a number of slave controllers.
