Performance evaluation of vehicle position and size information exchanged among vehicles in the V-PEACE scheme

摘要

This paper describes vehicle position accuracy exchanged among vehicles in the V-PEACE (Vehicle Position Environment Acquisition and Communication Evolution) scheme. Each vehicle in the V-PEACE scheme can exchange its position information each other by broadcasting pulses on TDM (Time Division Multiplex) frames. The pulse is transmitted at 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 with the position and the width of the pulse on the TDM frame. In this paper, the authors examine accuracy of the received information when exchanging position information pulses among vehicles on the road. The performance evaluation is carried out about accuracy of vehicle position information transmitted under the multipath environment in consideration of refection on the road, another vehicle and roadside wall surface via computer simulation.
