摘要 新型导向运输系统是一种面向车路协同环境、非轮轨接触式的中高运量道路公共交通方式,为保障其在公共路权下的优先通行权,该文提出一种前端无侵入式的路权优先策略,并设计与之适配的动态信号优先控制策略,从路段和交叉口两个层面实现导向车辆全运行过程的路权保障。通过算例对比了无路权优先、全时与间歇专用道、前端无侵入4种策略在不同路段交通条件下的适应性,以及与动态信号优先控制策略的协同效应。结果表明:前端无侵入策略适用于导向车辆行车间隔大于300 s的非密集运行状态,前端无侵入区间的长度应根据交通量确定;在"前端无侵入+动态信号优先"的组合策略下,导向车辆平均运行时间缩短13.24%,人均运行时间降低6.29%。

Abstract:Guideway transit system is a novel kind of trackless mass public transit. To give priority to guideway transit vehicles in the mixed traffic flow, a front-end non-invasive-based priority strategy is proposed to improve the overall operational efficiency of the system, along with a supporting strategy for implementing dynamic signal priority control (DSPC). A series of simulation experiments are conducted to compare the adaptability of four priority strategies (i.e., non-priority, full time or intermittent dedicated lane and the proposed front-end non-invasive strategies) in a wide range of traffic conditions. The results show that the proposed strategy fits into the non-intensive operation condition where the departure interval of the guideway transit vehicle is greater than 300 s. The length of the front-end non-invasive section ought to be determined by the traffic volume. Under the integrated strategy of front-end non-invasive strategy and DSPC, the mean travel time of guideway transit vehicle decreases by 13.24%, and the per person travel cost decreases by 6.29%.
