城市轨道交通环线在天津滨海新区的适用性研究

Adaption of Ring Rail Transit in Tianjin Binhai New Area

分析轨道交通环线形式以及与城市空间结构的关系,提出不同环线的适用范围。滨海新区为T型走廊城市,核心区为新区城市集中发展地区,呈现网络化、多片区的结构,城市中心与其他片区是偏中心的扇形放射关系。与城市结构对应,核心区未来客流分布以中心放射为主,同时在中心区边缘有一定环向客流需求,中心环放式轨道网络线既可有效满足于家堡中心放射客流需求,带动外围地区发展,同时也解决了中心客流压力过大等问题。

How different types of ring lines in rail transit should be used is discussed by analyzing the types of these lines and the relationship between the urban spatial structure and the ring line.Binhai New Area is a T-shaped corridor city,whose core area is for concentrated development,and is composed of many networked districts.Its urban space basically expands outward from the city center to other areas.Therefore,the future passenger flow in the core area of the city will mainly radiate from the core to the city center.At the same time,the edge of the city center will have a central ring distribution of passenger demand.The central ring plus radiating rail network can effectively meet the demand of radiating passenger flow from the city center to Yujiapu,guide the development of surrounding regions,and relieve passenger flow pressure in the city center.
