摘要
针对交叉口慢行交通出行路权分配不明确、过街距离过长等问题,开展结合彩色沥青引导的交叉口慢行交通组织优化研究。首先,研究适用于慢行交通的彩色沥青路面,进行彩色沥青原材料选择与配合比设计;其次,基于时空资源一体化设计原则,提出慢行交通组织优化设计方法;然后,以实际交叉口为例完成慢行交通组织优化设计方案;最后,采用VISSIM仿真软件验证设计方案的有效性。结果表明:彩色沥青路面有助于明晰慢行交通路权,减少慢行交通与机动车之间的冲突,缩短慢行交通一次过街距离,在此基础上考虑慢行交通协调式过街的相位配时设计,能够有效提高路口过街安全性和通行效率。
Aiming at the problems of unclear right of way distribution and long crossing distance of slow traffic at intersections,the optimization of slow traffic organization at intersections combined with color asphalt guidance is studied.Firstly,study on colored asphalt pavement for slow traffic,the selec-tion of color asphalt raw materials and the design of mix ratio are carried out.Secondly,based on the principle of space-time resource integration design,the optimization design method of slow traffic orga-nization is proposed.Then,the actual intersection as an example was to complete the slow traffic orga-nization optimization design.Finally,VISSIM simulation software is used to verify the effectiveness of the design.The results show that the paving color asphalt pavement is helpful to clarify the right of slow traffic,reduce the conflict between slow traffic and motor vehicles,and shorten the distance of slow traffic.On this basis,the phase timing design of slow traffic coordinated crossing is considered,which can effectively improve the safety and efficiency of crossing at intersections.
