A simulation study for the communication subsystem of Wireless Traffic Information Service System

Intelligent Transportation Systems are based on the acquisition of urban traffic information timely and accurately. This paper puts forward a prototype system of Wireless Traffic Information Service System(WTISS). In WTISS, vehicles equipped with wireless communication module are regarded as moving sensors on traffic network. Road-side station can get traffic status by analyzing data collected by equipped vehicles. This paper studies end-to-end delay, packet loss rate, hop counts and throughput of inter-vehicle communication, and also constructs WTISS simulation system based on Paramics, MySQL, NS2, awk and Matlab.
