【摘要】：中国城市已经进入整体性交通拥堵时代,对城市规模、网络拓扑和交通控制的合理建模将有助于治理交通拥堵。拓展了城市规模下的宏观网络交通模型,弥补了传统模型的缺陷,发展了交通拥堵指数模型,采用分位数回归实证检验了城市规模、网络结构与交通拥堵的关系。研究表明:车辆保有量、交通密度与土地利用程度(街区密度)密切相关,并影响土地和网络资源的变化或区域间的再分配;拓展到城市规模下宏观网络交通模型后,每条道路的拥堵程度与城市规模成正比。人口对大城市交通拥堵越具有显著正向作用,但小城市人口的适度集聚对交通拥堵有一定的缓解作用;建设用地对交通拥堵极为敏感,城市规模越小灵敏度越高,其中交通用地的增加将直接增强交通系统的承载能力;道路面积与城市交通拥堵保持正向关系;与此相反,城市道路里程对交通拥堵的作用始终为负,说明加密城市网络结构对交通拥堵治理意义更大。
[Abstract]:Chinese cities have entered an era of integrated traffic congestion. Reasonable modeling of city size, network topology and traffic control will help to control traffic congestion.The macroscopic network traffic model under the city scale is extended, the defect of the traditional model is made up, and the traffic congestion index model is developed. The quantile regression is used to test the relationship between the city scale, the network structure and the traffic congestion.The research shows that vehicle ownership, traffic density and land use degree (block density) are closely related, and affect the change of land and network resources or the redistribution between regions.The degree of congestion per road is proportional to the size of the city.The population has a significant positive effect on traffic congestion in large cities, but the moderate concentration of population in small cities can alleviate traffic congestion to some extent, construction land is extremely sensitive to traffic congestion, and the smaller the city size, the higher the sensitivity.The increase of traffic land will directly enhance the carrying capacity of traffic system; the road area and urban traffic congestion maintain a positive relationship; on the contrary, the effect of urban road mileage on traffic congestion is always negative.It shows that the network structure of encrypted city is more significant to traffic congestion management.
