发布时间：2018-08-05 19:38
【摘要】：考虑到城市公交网络的生成和演化受到城市道路交通网络结构约束的现实,利用复杂网络的最新研究分支-空间网络相关理论,构建了适于城市道路交通网络的DMG约束空间;生成了DMG空间约束下的公交站点分布规则,并基于嵌套最短路径,提出了一个城市公交网络的演化模型。以辽阳市道路和公交网络为实证对象,将模型的结果与实际统计数据结果进行了对比,发现模型的仿真结果与实际数据可以很好地吻合,表明了此模型的有效性;利用此模型对城市建设速率和城市公交建设速率的相互关系进行了分析,结果表明,当两者比值呈现2个极端时,公交线网密度都会呈现几何级数级的变化。这为进行城市建设和交通建设规划的速度问题提供了一个决策依据。同时,本模型也揭示了城市公交网络演化的一般规律,为城市公交网络演化的研究提供了一种新思路。
[Abstract]:Considering the fact that the generation and evolution of urban public transport network is constrained by the urban road traffic network structure, the DMG constraint space suitable for urban road traffic network is constructed by using the relevant theory of space network, which is the newest research branch of complex network. The distribution rules of bus stations under DMG space constraints are generated. Based on the nested shortest path, an evolutionary model of urban public transport network is proposed. Taking the road and bus network of Liaoyang city as an example, the results of the model and the actual statistical data are compared, and it is found that the simulation results of the model are in good agreement with the actual data, which shows the validity of the model. The model is used to analyze the relationship between the urban construction rate and the urban transit construction rate. The results show that when the ratio of the two is two extremes, the density of the bus network will show a geometric series change. This provides a decision basis for the speed of urban construction and traffic construction planning. At the same time, this model also reveals the general law of urban transit network evolution, and provides a new way for the study of urban transit network evolution.
