Application of vehicle ad-hoc network in traffic control systems

Abstract

Mobile ad hoc networks find use in a variety of areas which include rescue missions, battlefields and recently in intervehicular networks, generally known as Vehicular Ad-hoc Networks (VANETs). This paper proposes a model for use of VANETs in an advanced traffic signal control system within a simulation environment. The idea is to use vehicular ad-hoc networking to reduce the average delay per person at road intersections. The control system is designed with a generic and flexible logic that allows it to simulate a wide range of traffic signal control types and strategies. The strategies include mechanisms for deadlock and starvation avoidance at intersections. The capabilities of the control system are illustrated through a case study in which a simulation is done for a four-way intersection and the results of the simulation studied with respect to the objectives of the prioritization strategies. An evaluation of the implemented system is performed.
