Traffic Signal Controller


MICROTRANS is TOT Partner with CDAC (Government of India) for manufacturing of Adaptive Traffic Signal Controllers. This dynamic Vehicle actuated traffic control system isdesigned to address the highly heterogeneous traffic conditions by continuously assessing real-time traffic demand from vehicle detectors deployed at strategic locations. Based on the assessment, the system generates optimum signal timings for signal coordination in vehicle actuated mode of traffic signal operation, thereby minimizing stops and delay at traffic junctions and reduce overall journey time.

Cute is a vehicle actuated road traffic signal controller that controls thesignal lamps over wired medium. Cute is Area Traffic Control System (ATCS)compatible having features to perform at isolated intersections or as part of asynchronized chain of controllers. The controller supports remote monitoring andmanagement of signal plans over various medium of communication network.Optimized Solar power operation, PWM based intensity control of signal lamps, GPS/ Server based distributed time synchronization, pole mountable/plinth mountableminiature architecture are other features of Cute. Cute has beendeveloped by CDAC(T) under the "Intelligent Transportation System Endeavour(InTranSe) for Indian Cities" which is a National level Collaborative Research andDevelopment Program funded by the Department of Electronics and InformationTechnology (DeitY), Ministry of Communications and Information Technology,Government of India.

Scalability of Vehicle Actuation Controller to ATCS in Future

This methodology senses the traffic through non-intrusive loops, which areinstalled at appropriate positions in the junction. These sensors provide current trafficinformation to the controller through detectors mounted within the controller.

Simultaneously the data is sent to central control room server where the ATCS softwarereceives and processes the data to give proper commands to the intersectioncontrollers to allocate appropriate timings to the green signal. The controller essentiallyextends the green time corresponding to the command received from the control roomwithin the constraints of the maximum and minimum green times programmed. Thesystem thus puts in an effective control of the traffic flow throughout the area wherethe system is implemented.
