城市对外枢纽的存在保障了城市内外交通的互联互通，大量乘客选择于城市对外枢纽处接续城轨进入城市，这类乘客通常携带行李较多，相比通勤乘客而言对行程舒适性的要求更高。研究以城轨为主，常规公交为辅的乘客行程路线规划，能够以通过“规避”拥挤路段、调整交通工具的方式提高乘客行程舒适度、降低路网压力并吸引客流。利用网络爬虫从开放数据源获取乘坐城轨由北京大兴国际机场至北京市内各站点的运行时间及费用，与乘车出行对比分析北京市内城轨出行的可达性及优劣势。基于以上结果，设计针对接续城轨出行乘客的考虑拥挤程度等因素的广义费用，在广义费用的基础上设计通过划分子网络求解最短路的乘客行程路线规划算法。在算例分析中通过与已有路径规划系统提供的路线对比，证明本文算法能够为乘客提供更舒适的出行路线。

The existence of an urban external hub ensures the interconnection of urban internal and external transportation, and several passengers choose to transfer to rail transit at the external transport hub to enter the city. Passengers who enter the city usually carry more luggage and, consequently, require higher comfort than commuters do. Analyzing passenger route planning based on rail transit supplemented by other public transport modes can reduce pressure on road networks, improve passenger comfort, and further attract passenger flow by “avoiding” congested sections and adjusting transportation. This study uses the web crawler method to obtain the running time and cost of urban rail transit from Beijing Daxing International Airport to Beijing from open data sources, and it involves an analysis of the accessibility, advantages, and disadvantages of the Beijing rail transit network as compared to car riding. Based on the above results, a generalized cost is arrived at, considering congestion and other factors, for connecting urban rail transit passengers. Based on the generalized cost, a passenger route planning algorithm is designed to solve the shortest path by dividing sub-networks. When compared with the algorithms used to provide routes in the existing route planning system, the algorithm in this study provides a more comfor table travel route for passengers.
