摘要
城市地下隧道及车库联络道存在空间封闭、视线狭窄、出入口密集等不利于交通引导的特点。近年来,国内大型城市陆续建成多个地下隧道及车库联络道,运营后的效果差异显著,隧道内的交通引导体系各有特点。该研究基于北京市地下环隧建成及后续运营情况,结合近年来北京市城市地下隧道及车库联络道的使用情况,以及针对部分地下隧道及车库联络道的交通引导体系改造工程经验,研究总结出一套适用于多出入口城市地下隧道的交通引导体系。该体系根据地下隧道的特点和隧道内对交通引导的不利因素,进行了针对性改进,同时对指引逻辑、指引内容及指引系统的设备设施进行了系统化研究。在交通引导体系中采用了分级指引、环隧轮廓图形、数字出口编号、自发光版面及5G基站等技术,形成了完整的城市地下隧道及车库联络道交通引导体系。
Underground tunnels and garage connecting roads have characteristics of unfavorable to traffic guidance,such as enclosed spaces,narrow sightlines,and dense entrances and exits.In recent years,several underground tunnels and garage connecting roads have been built in major cities in China,with significantly different operational effects and different characteristics of traffic guidance systems in tunnels.Based on the construction and subsequent operation of the underground ring tunnel in Beijing,combined with the usage of urban underground tunnels and garage connecting roads in Beijing in recent years,as well as the experience of traffic guidance system renovation projects for some underground tunnels and garage connecting roads,a traffic guidance system suitable for urban underground tunnels with multiple entrances and exits is summarized.According to the characteristics of underground tunnels and the factors that hinder traffic guidance within tunnels,the guidance system has been specifically improved.A systematic study has been conducted on the guidance logic,guidance content,and equipment and facilities of the guidance system.Technologies such as hierarchical guidance,ring tunnel contour graphics,digital exit numbering,selfluminous panel,and 5G base stations have been adopted in the traffic guidance system,forming a complete traffic guidance system for underground tunnels and garage connecting roads.
