济南市BRT-1号线行车速度特性分析及改善建议

摘要

As an emerging public transport mode,Bus Rapid Transit (BRT) is an effective way to solve the traffic congestion problem in the city area because of its less investment,short construction period,effectiveness and other advantages.The BRT-1 in Jinan City uses closed station and dedicated lanes,which usually has higher operational efficiency compared with conventional public transport.However,there are many operation problems of BRT-1 vehicles,including relatively low travel speed.By using the manual investigation and portable GPS to collect the field data,this paper analyzes the speed characteristics curve and the time-varying as well as space characteristics of travel speed between stations and operating speed of the entire route.Finally,the paper proposes some improvement measures regarding the operation plan of the BRT-1.%快速公共交通作为1种新型的公交模式,因其投资少、建设周期短、见效快等特点已被作为解决城市交通拥堵问题的有效方式.济南中央岛封闭站台式BRT-1采用封闭式站台,具有BRT专用车道,相比常规公交具有较高的运输效率,然而BRT-1车辆在运行中也存在诸如运行速度相对低下等问题,采用人工调查及便携式GPS调查数据,从行车速度特性曲线,站间行程速度与全程行程速度以及时变特性,空间特性方面对行车速度进行了分析,并对济南市中央岛封闭站台式BRT-1车辆运行方案提出了几条建议.
