摘要
随着城市经济的快速发展和城市人口的迅速增加,城市的交通设施明显赶不上城市的发展速度,交通堵塞日趋严重。针对交通拥堵问题,运用复杂网络理论来分析乌鲁木齐市公交系统,以公交站点为节点、相邻站点之间的线路为边构建复杂网络模型。通过分析交通网络模型特性,发现乌鲁木齐市交通网络具有较小的平均路径长度和较大的聚类系数,数据分析显示具有小世界特性,少数节点在网络中有着重要的连接作用。通过分析关键节点来提高网络的鲁棒性,为优化城市公交网络和交通规划提供参考。
With the development of urban economy and the rapid increase of urban population, urban traffic facilities obviously couldn＇t catch up with the pace of development, traffic congestion has become increasingly serious. To the problem of traffic congestion, the complex network theory is applied to the analysis of Urumqi public transport systems. Taking bus stops as the nodes, edge lines between adjacent sites as the lines, a complex network model is set up. Through the analysis of traffic network model features, find that Urumqi transport network has the small average path length and large cluster coefficient, the results show that has small-world property. A few nodes in the network have an important role in connection. In this paper, by analyzing the key nodes to improve the robustness of the network, a reference for optimization of urban public transport network and transportation planning is provided.
