Abstract :
This paper describes vehicle position accuracy exchanged among vehicles in the V-PEACE (Vehicle Position Environment Acquisition and Communication Evolution) scheme. Vehicles in the V-PEACE scheme can exchange position information with each other by broadcasting pulses on TDM (Time Division Multiplex) frames. The pulse is transmitted with unique timing determined by the vehicle´s position on the road. A vehicle that received the pulse can distinguish the position and the length of the transmitting vehicle on the road from the position and the width of the pulse on the TDM frame. In this paper, the authors examine the accuracy of the received information when exchanging position information pulses among vehicles on the road. A performance evaluation is carried out concerning the accuracy of vehicle position information transmitted under the multipath environment with consideration of reflection on the road, other vehicles and roadside wall surface via computer simulation.
