A ZERO PUBLIC INFRASTRUCTURE VEHICLE BASED TRAFFIC INFORMATION SYSTEM

This paper introduces an innovative completely decentralized vehicle- based traffic information system that does not involve any public investment from government agencies to build, manage and maintain the necessary infrastructure; it relies, instead, on information exchanged by the vehicles themselves. We present the basic design issues and perform some initial analysis for an idealized freeway at various levels of market penetration and congestion. Relationships are derived for the propagation speed of the information wave versus that of the traffic shock wave in case of bottlenecks. On a network, similar results are produced from a modified simulator. Finally, the communication needs are analyzed assuming that the IEEE 802.11 wireless communication standards for inter-vehicle is adopted
