Abstract:
The Area traffic light coordinator has developed targeting to reduce high traffic congestion in Sri Lanka by
synchronizing traffic light controllers using dynamic phase selection and timing calculation with area
coordination. The software program which runs on the traffic light controllers, gets the vehicle density input
needed to calculate timing from a database, which should he updated dynamically using a sensor network.
Calculated timing and phases are then rearranged to suit with junction structure and using those,
synchronization not only within the junction, but also throughout the critical path is achieved.
