城市中央商务区地下交通系统规划

Design of Underground Traffic System in Central Business District

为缓解城市用地资源紧张与交通需求不断增长之间的矛盾,对中央商务区地下交通系统的规划设计方法进行了探索。在案例分析基础上总结城市中央商务区综合交通系统规划建设的成功经验,探索地下交通系统的平面和竖向布局模式,并对郑州龙湖金融中心地下交通系统进行实证研究。研究表明:地下交通系统作为地面交通系统的补充和延伸,能够通过建设地下轨道、地下道路、地下停车、地下人行通道等措施,提升交通承载力、平抑交通需求、实现人车分离,从而达到缓解交通压力的目的。

In order to alleviate the conflict between the shortage of land resource and the growth of traffic demand in cities,the method of planning and design of the underground traffic system in central business district is explored.Based on case study,the successful experience of construction in central business district is summarized and the plane and vertical layout of the underground traffic system is explored.The empirical study is adopted to research the underground traffic system of Longhu CBD in Zhengzhou.The study shows that the underground traffic system,as a complement and extension of the ground traffic system,plays an important role in increasing traffic capacity,stabilizing traffic demand,and separating pedestrians and vehicles to relieve traffic pressure through the construction of underground transportation infrastructure such as rail transit,roads,parking lots,and pedestrian paths.
