交叉口动态车道功能与信号控制协同问题研究
Study on Synergy Problem of Dynamic Lane-use Assignment and Signal Control at Intersections
摘要
Abstract
Based on the analysis of space-time relation of signalized intersections,an integrated model for lane-use assignment and signal phase was established using the traffic flow theory and signal control technology synthetically.In order to solve the model,a program was developed through Visual Basic programming.Actual road intersections were optimized by the program and optimal solutions were generated.Then both the origin plan and the optimal solutions were simulated with VISSIM to verify the model.The simulation results show that there is synergetic effect between dynamic lane-use assignment and signal control.Different from improving lane-use assignment or signal plan alone,synergy cann effectively improve the utilization of space-time resources at intersections,thus reducing the key traffic state parameters such as delay and queue length.关键词
