摘要:

为了保证有轨电车在交叉口享有信号优先的同时,使其按照运行图行车,在有轨电车干线信号协调模型BAM-TRAMBAND的基础上,增加运行图对行车的约束,包括发车间隔、停站时分、站间运行时分和干线旅行时间,提出2类不同约束的有轨电车干线信号协调优化模型,严格运行图约束的优化模型(HT-TRAM)和宽松运行图约束的优化模型(ST-TRAM). 经算例验证和仿真结果表明,改进的模型能够得到在运行图约束下的有轨电车上下行绿波带,且在算例条件下,两者的路段平均绿波带宽与没有运行图约束的带宽结果相比,相差在1s以内.

Abstract:

For considering the trams travelling as timetable and keeping signal priority, the timetable constraints including departure interval, stopping time, running time of section, and arterial travel time are supplemented in the model BAM-TRAMBAND. Two arterial signal coordination optimization models for trams are developed with hard constraints and soft constraints which named HT-TRAM model and ST-TRAM model separately. The case study and simulation results show that the modified models both got the arterial green- waves with timetable constrains for trams in two directions. Moreover, the average green-wave bandwidths with hard and soft constraints are both narrow less than 1s compared with BAM-TRAMBAND model.

Key words: railway transportation, arterial green-wave, MAXBAND, trams, signal priority, timetable
