摘要
面向城市道路交叉口在不同时段的交通流量变化特性,可变车道是提升交叉口通行效率的重要手段.针对交叉口可变车道的优化应用问题,提出了一种结合彩色沥青引导的交叉口可变车道优化及控制方法.首先,基于车道、相位和配时一体化设置原理,提出可变车道优化设置方法,提升可变车道设置及控制的合理性;其次,研究适用于可变车道铺装的彩色沥青材料,并在此基础上开展引导设计,提升可变车道应用的有效性;然后,以实际交叉口为例完成可变车道优化设计及控制方案;最后,采用VISSIM仿真软件验证了方案的有效性.仿真结果表明,该方法能够明显提高交叉口的通行效率.
Abstract
Considering the variations in traffic flow at urban intersections during different time periods,variable lanes are an essential means to improve intersection efficiency.Addressing the optimization and application issues of variable lanes at intersections,a method for optimizing and controlling vari-able lanes at intersections guided by colored asphalt is proposed.Firstly,based on the integrated princi-ple of lane allocation,signal phase and timing,optimal settings method for variable lanes to enhance the rationality of variable lanes setup and control were proposed.Secondly,the use of colored asphalt materials suitable for variable lanes paving and develop guidance design to enhance the effectiveness of variable lanes applications were investigated.Then,an optimization design and control plan for vari-able lanes using a real intersection as an example was also provided.Finally,we validated the effective-ness of the proposed approach using VISSIM simulation software.The simulation results demonstrate that the optimization and control method for variable lanes can significantly improve intersection effi-ciency.
