以轨道交通开通后的公交线网为研究对象,论文提出了公交线网优化规划的流程,包括现有公交线路调整与新增轨道接驳线路两部分,并分别进行重点分析。现有公交线路调整在公交线路形态分类的基础上,提出了基于不同分区以及不同重合站距数量的线路调整措施;新增轨道接驳线路主要分析了接运公交出行需求特征等,提出了“放射型与环型”两大类典型布局形态,并且探讨了轨道接运范围的确定方法,为线路布设提供重要依据。最后结合苏州市轨道交通1号线开通后公交线网优化规划进行实例应用和验证。 Taking the bus network after the opening of rail transit as the research object, the paper proposes the process of bus network optimization planning, including the adjustment of the existing bus lines and the addition of the new track link, which are mainly analyzed respectively. On the basis of the classification of bus lines, the existing bus line adjustment measures are proposed based on the different subareas and the distances between different coincidence stations. The newly added orbital feeder lines mainly analyze the demand characteristics of bus trips, “Radial and ring” two typical types of layout, and to explore the determination of the scope of rail transit to provide an important basis for the layout of the line. Finally, combined with Suzhou Rail Transit Line 1 after the opening of bus network optimization program for example application and verification.
