首发时间:2019-05-07
摘要:本文以城市交通网络流理论为基础,研究城市潮汐车道的设置对区域内路网交通分布状况的影响。根据潮汐车道的设置对路网设施的影响机理,对潮汐车道设置后的路网交通流量对自由旅行时间、路段通行能力及OD出行需求的敏感性进行研究分析,建立潮汐车道在均衡网络中的输入变量对路段交通量的敏感性方程,从而分析潮汐车道的设置对路网交通流的影响。通过分析潮汐车道设置前后路网上的路段流量的变化,为分析潮汐车道设置对路网的影响提供有效的解析方法。

The influence of tidal lanes based on sensitivity of network flow on traffic flow in road network
Abstract:Based on the theory of urban traffic network flow, this paper studies the influence of the setting of urban tidal lanes on the traffic distribution of road networks within the region. According to the influence mechanism of the tidal lane setting on the road network facilities, through analying the sensitivity of the road network traffic flow after the tidal lanes setting to the free travel time, the road section capacity and the OD travel demand on the balanced network, established the network input variables for the sensitivity equation of the traffic flow in the tidal lanes on the balanced network, thus analysis the tides lanes setting influence on road network traffic flow. By analyzing the change of the traffic volume on the front and rear roads in the tidal lane setting, an effective analytical method is provided for analyzing the influence of the tidal lanes setting on the road network.
Keywords: traffic engineering tidal lanes sensitivity balanced network road urban road network
