摘要
本文综述了城市道路交通网络可靠性的主要模型,针对诸多道路交通网络不可靠性因素,探讨解决城市道路交通网络可靠性评价体系,寻求路网结构合理化和交通运营优化,从动态时变性研究道路交通网络结构可靠性的时间冗余性、空间冗余性以及时间经济性和空间经济性。在分析全网可靠性的基础上,讨论公交网络可靠性对解决城市交通问题至关重要。
The paper reviews principal reliability models of urban road network, introduces multiple unreliability factors and discusses the reliability assessment system. Aiming to rationalize the road network structure and optimize the traffic operation, the research describes the time-space dynamic variation of road network, and further analyzes time redundancy, space redundancy, time economy and space economy of the reliability. Based on the entire road network reliability analysis, It is shown in this paper that improving the reliability of public transport networks is the key issue for urban road traffic.
