总结笔者承担的现代有轨电车设计工作，建立对现代有轨电车四个方面的认识：现代有轨电车是填补介于地铁与公交之间的运输需求，是与道路一体化的地面公交系统，是地面公交的升级，在运能、用地、通行量和运营成本方面具有比普通有轨电车更大的优势。借鉴世界大城市的应用经验，分析现代有轨电车在我国应用面临的挑战。从功能定位、交通条件、建设时机三个方面论述现代有轨电车的适应性；并提出现代有轨电车应用须研究的路权、车道布设方式、站台型式、进、出道口设站、路口信号优先和路口交通组织等六大交通要素。

With the tram design work, this paper summarizes the understandings of the modern tram design from four aspects，i.e., the modern trams satisfy the transportation demands between the subway and bus transportation; it is an integrated ground transportation system; it is the ground transportation upgrade; it is better than ordinary BRT in terms of the transport capacity, land usage, traffic volume and operating cost. By referring to the experiences of modern tram applications in large cities in the world, this paper analyzed the challenges facing modern tram’s in China, and then illustrated adaptability of modern tram from three aspects: the function, the condition of traffic and the opportunity of the construction; The paper in the end puts forward six traffic elements, i.e., way right, lane layout method, platform type, inlet and outlet station on the flat crossing, traffic signal priority and traffic organization, which should be investigated in the applications of modern tram.
