基于公交优先的虚拟导向列车路权定位研究

Research on the Right of Way Positioning of Virtual Guided Train based on Public Transit Priority

相比传统公共交通方式,虚拟导向列车具有运能大、投资省、建设快等诸多优点,但作为一种新型交通方式,其上路运营需先解决路权定位问题.论文首先介绍了既有的道路交通路权结构,并从空间和时间角度分析了国内外的公交路权定位策略.其次,结合虚拟导向列车的技术经济特性,从经济和效率角度出发提出完全独立,路段专用、交叉口共享等4种空间优先策略,以及交叉口"主动优先"的时间优先策略,并从硬件和软件2方面提出了相应的路权保障措施.最后,基于VISSIM微观仿真数据,对比分析了不同优先策略下的路权效益,得出路段专用、交叉口共享路权方案相对最优的结论.论文研究可为虚拟导向列车的上路运行提供理论和实际参考.

Compared with traditional public transportation modes,virtual guided trains have many advantages such as high capacity,low investment,and fast construction. However,as a new type of transportation,the right of road positioning should be solved first. This paper first introduces the structure of the existing right of road traffic,and analyzes the positioning strategy of bus with right of way from the perspective of space and time. Then,from the perspective of economy and efficiency,this paper presents four space priority strategies of complete independent,road segment-specific and intersection sharing,etc. Also,it presents the time priority strategy with active priority of road intersection,and proposes the protection measures of right of road from both hardware and software aspects. Based on micro traffic simulation,benefits of different priority strategies are analyzed,and the road segment-specific and intersection sharing scheme is relatively optimal. The research of the paper can provide reference for the running of the virtual guided trains.
