有轨电车共线运营下三通区的设计通过能力优化研究

Design and Capacity Optimization of a Three-Way Area for Trams

在多路有轨电车共线运营条件下,三通区作为共线段与非共线段连接交汇的区段,其通过能力将影响共线运营的效率。以武汉光谷现代有轨电车当代国际花园站三通区为例,对三通区进行研究和分析,并对其设计通过能力进行评估;从设计阶段出发,通过增加信号设备、分割长进路等方法,对三通区现有方案进行优化,并给出案例对比和分析,提出共线运营线路行车组织设计启示。结果表明,优化方案可在保证限速安全的前提下降低上下行的负荷度,有效提高三通区的设计通过能力。

In the co-line operation of trams, a three-way area is a section in which the joint line segment and the non-common line segment converge. The efficiency of the co-line operation will be affected by the capacity of this area. Taking the three-way area of the modern tram at the Modern International Garden Station in Wuhan Optics Valley as an example, the three-way area is studied and analyzed, and its design and passing capacity are evaluated. For the design stage, the existing schemes are optimized by adding signal equipment and segmenting the path, and a case comparison and analysis are given. A proposal for the organizational design of a common operation line is put forward. The results show that the optimized scheme can reduce the upstream and downstream load and effectively improve the design capacity of the three-way area while ensuring that the speed limit is upheld.
