摘要
文章研究了轨道交通线路对城市既有交通枢纽站点的影响。根据种间竞争的Lotka-Volterra模型,对衔接不同交通方式的两类交通枢纽的资源争夺关系进行了建模,通过对模型平衡点和稳定性的分析,得出了两类枢纽各自不同的发展趋势。最后,引入交通引导发展的理念,通过简单算例,指出了城市轨道交通对于交通枢纽发展的重要推动作用,为城市轨道交通的线网规划及交通枢纽的布局提供了借鉴思路。
This paper has studied the influence of rail transit line on existing transport hubs in cities.The resource competition about two kinds of transport hubs which connect different transportations is modeled according to the Lotka-Volterra model.By analysising the balancing point and stability of this model,this paper gives the trend of these two kinds of transport hubs.Finally,the concept that the traffic guides the development of city is introduced.The important role of rail transit in promoting the development of transport hubs has been demonstrated by an example.Thus,this paper provides a reference about the rail transit network planning as well as the layout of transport hubs.
