本文建立了湘潭市公交系统评价模型和评价指标体系,借助GIS技术对现状评价指标进行计算、分析和比较。结论表明:湘潭市现有的地面公交线路网存在线路过长、重复系数过大、非直线系数超标准等问题,这些结论为湘潭市公交线路网的后优化工作提供量化依据。 This paper establishes the evaluation model and evaluation index system of public transport system in Xiangtan City, and calculates, analyzes and compares the current status evaluation index with GIS technology. The conclusion shows that existing ground bus lines in Xiangtan have some problems such as long lines, excessive repetition coefficients and exceeding of non-linear coefficients. These conclusions provide the quantitative basis for the post-optimization work of the bus lines in Xiangtan.
