Tram Operation Indicator Analysis Method Based on Randomness Feature and Combined Simulation Model

考虑到有轨电车运行指标比一般的轨道交通更具随机性,提出将轨道交通列车牵引计算引入道路交通仿真环境,将有轨电车在线路运行过程与道路交叉口信号优先控制形成实时相互反馈的分析方法。采用该分析方法对不同规划和运营方案进行仿真分析,即可得到有轨电车全线和局部运行指标的分布特征及总体评价。具体案例的计算结果表明,在规划设计阶段,根据线路的布局方案及列车运行计划规划,采用该分析方法仿真计算有轨电车的运行指标,能有效评价道路随机性影响程度,为有轨电车规划设计方案的评估与决策提供依据。

Considering that tram operation indicators are more random than those of common rail transit,an analysis method is proposed,where rail transit train traction calculation is introduced to road traffic simulation environment,and a real-time inter-feedback is formed between tram operation process on route and road intersection signal control priority.The analysis method is used on simulation analysis of different plannings and operation schemes,the distribution characteristics and overall evaluation of general and partial tram route indicators are obtained.Calculation results of practical case show that,at the planning and design stage,according to line layout scheme and train operation planning,the adoption of this analysis method to simulate and calculate tram operation indicators can effectively evaluate road randomness influence level,providing evaluation and decision-making reference for tram planning and design scheme.
