摘要

针对交通物联网中单点定时信号配时问题，将微观层面分析法和宏观层面分析法相结合，提出了一种基于改进Webster方法的配时方案。以饱和度和信控延误为优化目标，建立单点的平均延误模型；针对无信号控制和有信号控制的单交叉口分别建立博弈模型和冲突模型，并进行冲突分析；基于改进Webster方法，额外考虑了机动车通过单点所需最短时间，提出了单点信号配时三步优化方案以减少延误。仿真结果证明了所提方案的有效性。

Abstract

Aiming at the timing signal problem of single intersection

a timing method based on the improved Webster algorithm in transportation Internet of things was proposed by combining the micro level analysis method with the macro level analysis method.In order to optimize the saturation and signal control delay

the average delay model was established.The game model and the conflict model were established with non-signal control and signal control.And the conflict analysis was carried out to illustrate that the optimal signal timing could coordinate the conflicting traffic flow.Based on the improved Webster algorithm

the shortest time required for the motor vehicle to pass the single intersection was additionally considered and a three-step optimization method for timing method at single intersection was proposed to reduce the traffic delay to ensure that the vehicle could pass effectively.The simulation results illustrate the effectiveness of the proposed solution.
