基于TransModeler软件的公交信号优先模型研究

Study on Bus Signal Priority Model Based on TransModeler Software

随着公交优先思想的逐渐被接受,作为实现公交优先的主要方式——公交信号优先自然被提上议程。针对大中城市道路交通拥堵、公交运行缓慢等状况,应用微观交通仿真软件TransModeler建立路网车辆运行模型。以哈尔滨市第5路公交为实例,提出公交信号优先方案,应用TransModeler对其进行仿真。通过仿真结果对方案实施前后各路段的交通流运行状况的评价,证明论文提出的方案具有一定的科学实效性。同时表明应用TransModeler软件可以快速、有效的实现各个路网优化方案的对比,节省繁琐数据输入的时间,仿真输出数据简单明了,对今后公交线网优化有很大的帮助。

With the bus priority ideas gradually accepted, bus signal priority as the main way to achieve bus priority is put on the agenda. According to the traffic problems in large and medium-sized cities such as traffic congestion and buses moving slowly, the mi- croscopic traffic simulation software TransModeler was used to establish a road network vehicle operating model. In this paper, the No. 5 bus in Harbin city was used as an example to propose a bus signal priority plan, which was simulated by TransModeler. Based on the evaluation of the simulation results before and after implementing the optimized solution in all sections of the traffic flow, the proposed plan has proved to be scientific and effective. Meanwhile, it is showed that the application of TransModeler software can compare each optimized solution quickly and effectively, and save tedious data entry time. The simulation output data is simple and clear, which is very helpful for optimizing bus transportation network in the future.
