地下道路出入口交通组织研究

目前,地下道路出入口通行能力降低、交通组织混乱的问题已成为地下道路建设与管理亟待解决的问题.文章从分析地下道路出入口交通拥堵的现状入手,提出了地下道路出入口交通组织设计应遵循的原则和主出入口布置的指导思想.在此基础上,进一步设计了主出入口分别与十字型路口、正T字型路口、竖T字型路口衔接时的交通组织模式;根据合流区和分流区车流特性,进行了合流区和分流区交通组织设计,该项的研究可为地下道路的规划、设计和管理提供重要的技术支持.

Research on Traffic Organization at the Entrance and Exit of Urban Tunnel

At present,at entrance section and exit section of many urban tunnels the traffic organization is disordered,and the traffic capacity is low,which is a problem that should be solved for urban tunnel construction and management.From the traffic congestion actualities of entrance and exit section of urban tunnel,the presented paper brings forward the principles to follow for traffic organization design at entrance and exit of urban tunnel,and puts forward the guidance ideas to lead how to lay out the entrance and exit,and furthermore,it puts forward different traffic organization styles according to different link styles between the primary entrance and exit and adjacent crossing such as intersection,T crossing and upright T crossing.Based on traffic flow characteristic,the presented paper brings forward the traffic organization at merging and diverging areas.Research on traffic organization in the presented paper will provide important technology support for urban tunnel planning,design and management.
