Research on induction signal control method of queuing length

Abstract

This paper aims at the problems of traditional induction signal control. By comparing the advantages and disadvantages of other timing signal control methods and induction signal control methods, an induction signal control method based on queuing length is proposed. The signal setting method of induction signal control method based on queuing length is analyzed in combination with the characteristics of queue length change and traffic flow. The method presented in this paper is introduced to optimize the length of the green light in the various phases of the previous period, the number of vehicles and the length of the queue, to predict the average head time distance and the queue length of the next cycle, so as to calculate the green light time and the period length of the next cycle of the intersection. At last, VISSIM simulation software is used to compare and analyze the traffic efficiency of induction signal control and traditional induction signal control based on queuing length, and verify the adaptability, feasibility and effectiveness of the scheme.
