摘要: 城市道路交通网络区域划分是实现区域交通控制与交通诱导的前提和基础,正确的交通区域划分能显著提高城市区域交通控制与诱导效率。将城市道路交通网络抽象为以路段行程时间为权值的复杂网络结构,采用分裂算法中的GN算法,提出道路交通网络模块度函数实现路网区域划分;并根据复杂网络中强社团与弱社区的概念提出道路交通网络中强连接区域与弱连接区域定义对划分结果进行评价;同时与无权道路交通网络区域划分结果进行对比评价。结果表明:该城市路网区域划分方法划分结果合理。

Abstract: The regional division of urban road traffic network is the premise and basis for realizing regional traffic control and traffic guidance, and correct traffic area division can significantly improve the efficiency of traffic control and guidance in urban areas.The urban road network was abstracted into a complex network structure with the travel time as the weight value.By using GN algorithm in the split algorithm,the modulus function of the road traffic network was proposed to realize thearea division of road network.According to the concept of strong community and weak community in complex network,the definition of strong connection area and weak connection area in road traffic network was proposed to evaluate the division results.At the same time, the obtained regionaldivision results were compared with thoseof unweighted road network.The results show that the division results of the proposed regional division method of urban road network are reasonable.

Key words: traffic engineering;GN algorithm, modulus function, edge betweenness, strong connection area, weak connection area
