The Characteristics of Traffic Congestion from the Perspective of Spatial Structure, Urbanization, and Motorization in Chongqing

This work analyzes the particularities on present urbanization, urban spatial structure with "multi-centre and cluster-mode," and motorization of the main urban area in Chongqing. In addition, the characteristics of traffic congestion are analyzed from the perspective of time and space evolution. The characteristics show that the congestion sources are combined with congestion points and regionalized; the congested points locate in connections between clusters, and transportation supply is insufficient; traffic congestion occurs intensively during the morning and evening peak hours and is in the stage of duration extension. The characteristics indicate that the traffic congestion in the inner-ring urban areas of Chongqing is getting worse with more congested regions and last longer than peak-hour duration. Finally, the ideology on congestion management is proposed briefly in the aspects of urban spatial structure, public transit, traffic-demand management, and travel civilization.
