基于多源数据的无锡轨道交通客流特征分析

无锡轨道交通线网已经初步形成，但整体线网负荷强度偏低。为提高轨道交通规划管理水平，有必要对轨道交通客流特征进行研究。基于居民出行调查、地铁乘客出行特征调查、轨道交通 AFC 数据等多源数据，分析无锡市轨道交通客流特征、轨道交通与土地利用的协调关系、轨道交通与其他交通方式一体化水平等，并与上海、广州、深圳、成都等城市进行对比分析。结果表明，轨道交通线网的平均乘距为 8.4 km，可较好地服务于核心区与外围组团间的中长距离出行；沿线开发强度、居住和岗位覆盖率偏低，影响轨道可服务人群数量；与常规公交等交通方式衔接不足，降低轨道交通快速出行竞争优势。研究建议无锡市应重点加强轨道交通与城市空间的耦合，提高沿线开发强度，协调轨道交通与其他交通方式的衔接，充分发挥轨道交通效能。

Passenger Flow Characteristics of Wuxi Urban Railway Based on Multi-Source Data

The urban railway in Wuxi is currently in a start-up stage. To better explain the low load intensity of the urban railway network and improve the level of planning and operation management, it is necessary to study its passenger flow characteristics. Based on household and passenger surveys and automatic fare collection (AFC) data, the passenger flow characteristics, relationship between the urban railway and land use, and transfer characteristics were all analyzed in this study. The results were compared with the characteristics of urban railways in Shanghai, Guangzhou, Shenzhen, and Chengdu. The results showed that: a) the average riding distance was 8.9 km, and Wuxi urban railway mainly served medium and long distances between central and peripheral areas; b) the lower level of land development, population density and job density along the urban railway routes, the lower was the number of potential passengers; c) the greater convenience and integrity of the transfer facilities in rail stations had compromised the competitive advantage of the urban railway. Finally, the study provides suggestions for enhancements to the urban railway, including improving the coordinated development of urban transportation and land use, promoting land use development along the rail transit lines, and improving the convergence between the urban railway and a variety of other transport modes.
