Research on Traffic Management Ideas and Countermeasures in the Central Urban Area of Megacities
[Purposes]To improve the pertinence of traffic management measures and improve the effi-ciency of construction fund investment,it is necessary to study the traffic management ideas of the central urban area of megacities.[Methods]Using international case comparison,induction and deduction re-search methods,a comparative study was conducted on the characteristics of the transportation operation status of typical mega cities at home and abroad.[Findings]It was found that the traffic congestion in the central urban areas of mega cities in China has been significantly better than that of developed overseas megacities with similar population size and spatial structure.Under the support of new transportation tools such as rail network and shared bicycles,the mode of transportation for residents has undergone sig-nificant changes,and the marginal effect of continuing to increase the capacity of motor vehicles in an at-tempt to alleviate traffic congestion is significantly decreasing.[Conclusions]In the context of signifi-cant changes in motorized transportation modes and the construction of low-carbon cities,the focus of traffic governance in China's mega cities should be adjusted,and more attention should be paid to the co-ordinated development of rail transit and land,the overall improvement of slow traffic space environment,and the effective supply of high-quality and diversified transportation.
