Green Wave Coordination Through Wireless Traffic Light Controller System

The battle against traffic jams and urban traffic congestion has become increasingly efficient with the use of new techniques and technologies for traffic signal management devices. To contribute to urban traffic management, this article proposes a mathematical model for semaphore initialization to implement a new approach to the Green Wave (GW) technique into wireless traffic light systems. The mathematical model was employed within a wireless traffic light controller system, which communicates via the XMesh wireless network. To test the success of this mathematical model, practical tests were carried out using a wireless traffic light controller system. The results indicated that even in faulty situations, the system can alert not only drivers at the intersection, but also the management center.
