【摘要】：随着我国城市化和机动化进程的加快,各大城市的车流量急剧增加,原有的道路设施已经不堪重负,交通拥堵状况越来越严重,已成为各大城市亟须解决的重要问题之一。为了解决城市交通拥堵,大力发展公共交通,实行“公交优先”的战略,进而促进城市经济发展、提高道路资源利用率。但是由于缺少实时动态的网络化公交调度方法,使得智能公交调度平台并不能充分发挥其作用,很难有效的提高车辆准点率、车内舒适度以及乘客等车时间等公交服务水平。因此,对公交调度的网络化和动态化研究显得十分必要。论文依托国家自然科学基金项目“面向车辆调度的公交动态网络复杂性及其实证研究(No.51308176)”内容来展开研究,对城市公交运营网络的相关特性以及网络化和动态化的调度策略展开研究。首先,以公交车辆在网络上的运行轨迹为原型,构建以公交停靠站点作为网络的节点,车辆在网络上的实时位置作为网络边的城市公交动态网络。车辆在城市道路网上位置的实时变动使得构建的公交网络具备了时变的特性。其次,利用不同的建模机制对城市公交动态网络模型进行抽象,对得到的公交网络拓扑结构以及相关动力学特性进行研究分析,为网络化车辆调度提供一种新的思路。然后,分析一路一线和多路多线公交动态模型的车流特性,对网络的统计学特性进行研究,通过实例仿真分析,提取网络相关的特征参数作为识别公交分布状态的重要指标。最后,对异常状态下公交的实时运营状态进行分析,并且通过制定相应的公交动态控制策略使得网络趋于稳定。通过上述分析,将复杂动态网络理论的分析方法引入到公交调度领域,提出了一种新的解决公交调度问题的途经,体现出可行性和先进性。
[Abstract]:With the acceleration of urbanization and motorization in China, the traffic flow of major cities has increased sharply, the original road facilities have been overwhelmed and traffic congestion has become more and more serious, which has become one of the important problems that need to be solved urgently. In order to solve urban traffic congestion, develop public transportation vigorously, implement the strategy of "public transportation priority", and then promote the development of urban economy and improve the utilization rate of road resources. However, due to the lack of real-time and dynamic network bus scheduling methods, intelligent bus scheduling platform can not fully play its role, and it is difficult to effectively improve the bus service level, such as vehicle punctuality, in-vehicle comfort and passenger waiting time. Therefore, it is necessary to study the network and dynamic of bus dispatch. Based on the National Natural Science Foundation of China (NSFC) project, "the complexity of bus dynamic Network for vehicle Dispatch and its empirical Research No. No. 51308176)", the thesis carries out the research. The related characteristics of urban transit network and the network and dynamic scheduling strategies are studied. First of all, based on the track of public transport vehicles in the network as a prototype, the bus stop as the node of the network, the real-time location of the vehicle in the network as the network of urban public transport dynamic network. The real-time change of vehicle location on the urban road network makes the constructed bus network have the characteristics of time-varying. Secondly, the dynamic network model of urban public transport is abstracted by different modeling mechanisms, and the topological structure and related dynamic characteristics of the network are studied and analyzed, which provides a new way of thinking for networked vehicle scheduling. Then, the characteristics of traffic flow in the dynamic model of one route and multi-route bus are analyzed, and the statistical characteristics of the network are studied. Through the simulation analysis, the characteristic parameters related to the network are extracted as important indicators to identify the distribution state of public transportation. Finally, the real-time operation state of public transportation in abnormal state is analyzed, and the network tends to be stable by making the corresponding dynamic control strategy of public transportation. Through the above analysis, the analysis method of complex dynamic network theory is introduced into the field of public transportation dispatch, and a new way to solve the problem of public transportation dispatch is put forward, which embodies the feasibility and advanced nature.
