基于Anylogic仿真的现代有轨电车信号优先影响研究——以成都市有轨电车蓉2号线为例
|
摘要
现代有轨电车在道路交叉口通常采取信号优先使其优先通过,其运行会在一定程度上阻碍其他车辆的正常行驶。为了研究其信号优先对社会车辆造成的时间延误影响,本文对均匀分布的车流,提出两种主动优先控制策略下车辆时间延误的计算模型。最后基于成都市现代有轨电车蓉2号线中西源大道与郫温路的道路交叉口交通数据,利用anylogic仿真,分别对该交叉口采取固定配时、绝对优先、相对优先策略的车辆延误进行适应性分析。分析表明,在该交叉口中采取信号优先措施,降低了车辆的整体延误,其中相对优先的整体延误值最低。
Usually it takes the priority of signal for Modern Trams on intersections to ensure their smooth through, which hinders other motor vehicles' normal drive. In order to research the impacts of time delay on other vehicles on that point, this paper presents an original calculation model for two kinds of controlling strategies on its priority on the premise of uniform distribution on traffic flow. At last, take the data of Rong NO.2 in Chengdu for example to simulate the condition of one intersection by anylogic. Compared with 3 types of controlling strategies' results, it concludes that in this intersection, the time delay could be decreased if it it takes the priority of signal, in which the impact of middle priority' is the lowest one.
