摘要/Abstract

摘要： 运用马氏理论, 分析了城市道路平面交叉口红绿信在一般指数环境下交替更新时的车流量动态随机
模型。得出的结论与不饱和交通流在定时控制条件下进行比较, 证明了结果的有效性。最后提出平面交叉口绿灯
信息控制不仅应考虑延误时间和通行效率, 还应考虑车流量的更新周期。

Abstract:

According to Markov theory, dynamic stochastic model of vehicle flux of plane intersections of city roads was investigated under generic exponential renewal environment on red and green light information. The acquired conclusions were compared with conventional timed control with unsaturated vehicle flux. The results prove the effectiveness of the stochastic model. Finally, green signal control in intersections not only considers delay time and passing efficiency, but also calculates renewal cycle.
