Vehicular ad hoc networks (VANETs) have emerged as a serious and promising candidate for providing ubiquitous communications, connecting vehicles to other vehicles traveling on the roads or vehicles to the Internet and other wide-area networks. This emerging communications platform can facilitate a number of vehicular applications especially those that fall into the Intelligent Transportation Systems domain. In this talk, we propose and present the recent efforts of one of the ITS application, namely the Virtual Traffic Light (VTL) application. VTL is a self-organizing traffic control scheme that proposes the migration of traffic lights as roadside-based infrastructures to in-vehicle virtual signs supported only by vehicle-to-vehicle communications. It was proposed with an aim to address and alleviate the traffic congestion problem which has been worsened for the past decade. The VTL protocol was designed to be able to dynamically adjust its operation to optimize the flow of traffic in road intersections without requiring any roadside infrastructure. The talk will conclude with compelling evidence that our proposal is a scalable and cost-effective solution to urban traffic control and practice issues regarding the implementation and actual deployment of the proposed VTL framework.
