Research on Vehicles Position Evaluation Algorithm of Highway Tunnel

Abstract

t is very important to improve the quality of road managing, energy conservation and emission reduction to achieve lighting energy saving of highway tunnel. It used cloud model and processed the pulse waveform data when the vehicle went through loops to estimate speed; it kept the estimation of speed as the decision basis of vehicles position to estimate the vehicles position; at last, it was supposed to make the error of position estimation correct real-time to judge the position of vehicle accurately, which lighting equipments were controlled by lighting controller, so as to realize illumination on demand. The simulation and experiment results show that the algorithm can realize the measurement of vehicles position inside the highway tunnel, for purpose of energy conservation and emission reduction.
