道路交叉口车辆起动波波速的实时算法
Real-time Algorithm of Vehicles Start Wave Speed at Signalized Intersection
摘要
Abstract
Objective]The speed algorithm of the intersection starting wave of the vehicle was improved,in order to solve the real-time and accurate prediction of the starting wave speed.[Methods]In view of car-following dynamics,the starting speed of the vehicle is regarded as the average value of the propagation velocity of the moving state of all the neighboring vehicles in the fleet,and a new speed algorithm of the intersection starting wave is derived.[Results]Com-paring the theoretical value with the measured data at a typical signalized intersection,more than 75% of samples are in the range of error allowed.[Conclusion]The scientific nature and feasibility of the new algorithm are verified.This algorithm provides a new theoretical basis for the traffic signal control of the road intersection.关键词
