近几年来世界上许多城市正在逐步推广另一种快速公共交通方式,称为城市快速公共汽车运营系统(简称快速公交系统)。快速公交系统是利用改良型的公交车辆,运营在公共交通专用道路空间上,保持轨道交通特性且具备普通公交灵活性的一种便利,快速的公共交通方式。快速公交在城市公共交通系统中的运用的形式可以根据各个城市的交通需求,城市土地规划,以及城市的财政状况来决定。根据北京具体情况,针对“前门——天坛”典型狭窄路况的BRT线路运行分析,为北京的BRT系统覆盖提出有意义的借鉴。 In recent years, many cities in the world are gradually promoting another type of rapid public transport called the Urban Rapid Transit System (BRT). The BRT system is a convenient and rapid mode of public transport that uses improved buses, operates on dedicated road spaces for public transport, maintains the characteristics of rail transit and has the flexibility of ordinary public transport. The use of BRT in urban public transport systems can be determined by the transport needs of each city, urban land planning, and the financial status of the city. According to Beijing’s specific conditions, the operation analysis of BRT line in the typical narrow road of “Qianmen-Tiantan” presents a meaningful reference for Beijing’s BRT system coverage.
