城市交通网络效率的度量方法及其应用

The efficiency of the urban traffic network measurement method and its application

综合考虑网络中交通需求、路段流量、旅行时间等提出交通网络运行效率的度量方法,在设定的交通网络拓扑结构中,根据交通网络运行效率的变化趋势和城市道路的实际运行情况,选择出城市当中拟建道路的最佳建设方案,达到对城市当中拟建道路的方案进行评选的目的,然后运用网络组件的重要度评价方法对交通网络中的路段重要度进行排序,根据交通路网中的组成部件重要度排序,指导城市交通管理部门的管理以及交通设施的合理配置。

Considering the network traffic demand, road traffic and travel time transportation network efficiency measure is put forward, in the setting of traffic network topology, according to the tendency of the traffic network operation efficiency and the practical operation of city road, we can choose the best construction scheme of urban planning road, achieve the cities planned road scheme for the purpose of selection, and then USES the component importance evaluation method of the network to link importance sorting in traffic network, according to the components of the traffic network important degree of sorting, guide the management of urban traffic management department and the reasonable configuration of traffic facilities.
