Abstract: It is the key problem that whether the accessibility of the high-speed railway station in satellite city can be accurately analyzed to evaluate the distribution ability of the public transportation system to the high-speed railway passenger flow and optimize the routes and stations. In order to solve this problem, based on the passenger flow characteristics of high-speed railway in satellite city, a calculation model of public transport accessibility from “spot” and “panel” was proposed, which calculated and analyzed the public transport accessibility of high-speed railway station from “spot” and “panel”, in order to accurately locate the shortage of public transport stations and routes. Finally, the above methods were verified in the case of GIS simulation technology, and the analysis methods and results were given. The results show that the proposed model can accurately locate the local and overall deficiencies of the public transportation system, and provide the optimization direction of the system, which verifies the rationality and practicability of the proposed method.

摘要： 能否准确分析卫星城高铁站的公交可达性，是评判公交系统对高铁客流的集散能力，进行线路和站点优化的关键问题。针对这一问题，基于卫星城高铁客流特性，提出了一种由“点”及“面”的公交可达性计算模型，分别从“点”和“面”两个角度对高铁站公交可达性进行计算分析，以求准确定位公交站点和线路不足。最后结合GIS仿真技术在实例中对上述方法进行验证，给出分析方法和结果。结果表明：该模型可以准确定位公交系统局部与整体的不足，并提供系统的优化方向，验证了该方法的合理性和实用性。
