摘 要: 为提高复杂路网交通管理的效率和有效性,基于信息核度(information centrality,IC)的基本思想,提出了路网重要路段的确定方法。研究的特色在于:1) 从输送效率、连通效率和综合效率3种不同的角度表征了路段的交通功能;2) 综合考虑平均最短路长度及其通行能力两方面因素设计了路网的输送效率函数。实证分析表明,所提出的方法具有可行性和实用性。
关 键 词: 交通运输系统工程;重要路段;信息核度;路网;交通管理

Abstract: In order to improve the efficiency and effectiveness of traffic management in complex road network, this paper proposed the core link identifying method in road network structure on the basis of the fundamental idea of information centrality (IC). The characteristics of which included the following two aspects: 1) the traffic function of links were characterized respectively from transportation efficiency, connective efficiency and comprehensive efficiency different angles; 2) the design of efficiency function of road network combined with the consideration of the mean shortest route length and its capacity. A case study based on actual road network had been carried on, and the results showed that the proposed method had the feasibility and practicability.
Key words: transportation system engineering; core link; information centrality; road network; traffic management
