Integrated Tram Simulation System: Design and Implementation

城市道路交叉口的混合路权是影响现代有轨电车在交叉口通过能力的主要因素,也是工程设计的最大难点,因此设计并研发了一套具备全线路运行仿真评价功能的现代有轨电车一体化仿真系统。该系统具有混合交通环境建模、运行图与交叉口信号方案协调性分析、多交路及成网运行仿真、多用途评价指标输出及可扩展接口等特色功能。仿真运行过程反映有轨电车在区间运行的牵引动力学特征、安全追踪、列车折返以及过岔等作业细节,仿真结果可用于评价交叉口的混合路权及信号控制策略对现代有轨电车运行的影响效果,并结合具体案例展示该仿真系统的基本功能和部分输出指标。该系统有望为现代有轨电车规划设计方案的全面评估提供量化支持。

The non-exclusive right-of-way at urban road intersections is the main factor influencing the capacity of modern trams and the greatest difficulty in engineering design. This study designs and develops an integrated simulation system for modern trams, called the Easy Tram system, with the operation simulation of the entire line and evaluation function. This system has many features, such as mixed traffic environment modeling, analysis of the coordination between the tram operation diagram and the signal scheme at intersections, simulation of the multi-routing and network operation, output multi-purpose evaluation index, and extensible interface. The simulation process reflects the traction dynamic characteristics of the train running in the section and the details of safety tracking, train turning back, and passing switch. The simulation results can be used to evaluate the modern tram＇s characteristics of the mixed road right at the intersection and its adaption to the signal control. Finally, combined with the specific case, this study demonstrates the basic function and role of the output specifications of the simulation system. The Easy Tram system is expected to provide quantitative support for the overall evaluation of the planning and design scheme of a modern tram.
