广州金融城有轨电车与无轨电车的系统运能分析

现代有轨电车和储能式无轨电车都属于节能环保的新型城市公共交通。以广州都会区规划的金融城线为例,对半专用路权下有轨电车和无轨电车的运营组织和运能进行了分析。其中,着重分析了二者的路口通行能力和车站通行能力。分析结果表明:在半专用路权条件下,路口通行能力是系统运能的瓶颈;在提供同样运能服务水平的条件下,无轨电车所占用的路口通行相位时长比例低于有轨电车,无轨电车在车站段占用的道路宽度大于有轨电车。二者各有优劣,应根据实际情况选择。

Capacity Analysis of Financial Center Tramway and Trolleybus in Guangzhou City

Tramway and trolleybus with energy storage system are new types of urban public transport featuring energysaving and environmental protection.Taking the planned transit lines in Guangzhou Financial Center as an example,the traffic organization and capacities of tramway and trolleybus in semi-exclusive right-of-way are analyzed and compared,including their intersection capacities and station capacities.The results show that in semi-exclusive right-of-way condition,the intersection capacity is the bottleneck of two systems.Providing a condition of same capacity,the occupying ratio of trolleybus in the intersection traffic light is lower than that of tramway system,while the trolleybus occupied road width in the range of the station is greater than that of the tramway system.So,the selection of traffic model shall fully consider their advantages and disadvantages.
