有轨电车单线单向环线在老城区的适应性分析

Adaptability Analysis of Single-line One-way Tramcar Loop in Old Townown

有轨电车在城市的老城区布设时,线路的客流规模较大,有利于推行公交优先,有效缓解城市的交通拥堵。但是,由于老城区一般道路相对窄小,常规的双向有轨电车线路会占用过多的道路资源,因此分析设置单线单向环线的可能性及其适应性。以国内某城市郊区核心区有轨电车的线网规划方案为例,从线路运营组织、机动车交通组织、关键路段与交叉口服务水平等方面,将单线单向环线方案与常规双向方案进行对比,分析有轨电车单线单向环线在老城区的适应性。

When the tramcar is developed in old town,the large scale of passenger flow is conducive to the implementation of public transportation priority and the alleviation of urban congestion.However,because of the relatively narrow roads in the old town,too much road resources will be occupied by the conventional two-way tramcar lines,therefore,the feasibility and adaptability of single-line one-way tramcar loop is analyzed.Taking the tramcar and network planning in a suburban core area of a Chinese city as an example,the single-line one-way tramcar loop scheme is compared with conventional two-way tramcar line scheme from aspects of line operation organization,motor vehicle traffic organization,service level at key sections and intersections,so as to analyze the adaptation of single-line one-way tramcar loop in old town.
