一个公交主导型交通枢纽的现场调查分析

北京市国贸桥交通枢纽拥有庞大的公交运输车队，但难以应付过于集中的晚高 峰期出行需求.本文对国贸桥周边 1.1 平方公里内停车场、地铁、公交车站及周边大厦交通 需求展开广泛细致的交通调查，重点分析了 10 个公交车站的 116 条公交线路的公交运行 情况.通过对公交出行客运量、公交车辆到站时间间隔、乘客候车人数及候车时间等运行 指标进行深入分析，找出国贸桥交通枢纽运行过程中存在的问题并提出建议.本研究对公 交主导型大城市交通系统的建设和运营管理具有一定的借鉴意义.

Investigating a Transit-oriented Transport Hub in Beijing

A fleet of buses which is serving passengers around the Beijing’s World Trade Bridge is facing such a problem that the evening peak demands cannot be well digested. This paper presents a case study asso- ciated with this transit-oriented transport hub, through collecting demand and supply data of parking lots, sub- way station, bus stops and main buildings located in the area of 1.1 kilometer squares. Operations of 116 bus lines passing 10 stations, like the passenger arrival rates, bus arrival intervals, passengers for waiting and the waiting times, are particularly analyzed. Suggestions for well developing the transit-oriented transport hubs in big cities are provided.
