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%.
