作好城市轨道交通线网规划提高其社会经济效益

Proper Planning of Urban Rail Transit Network for Increasing Its Social and Economic Benefits

城市轨道交通已成为大城市解决交通拥堵,优化城市布局的主要手段,但轨道交通投资过高,造价昂贵,城市财力难以承受。如何降低轨道交通造价已成为急待解决的重大问题。本文分析了轨道交通线网规划对城市轨道交通造价、轨道交通运营效益和社会效益的影响,探讨了轨道交通的模式组合问题、轨道交通与其他方式的衔接与匹配、客流预测、轨道交通的线网规模、轨道交通线网空间结构形态等关键问题。

Urban rail transit has become a main means to release metropolis' traffic congestions and optimize the city layout, but the urban rail transit lines need huge investment. Its construction cost is too high for the city's finance to afford. How to reduce the construction costs of urban rail transit lines has been an urgent important problem.This paper analyzed the influence of urban rail transit network planning in its construction costs, operating benefits and social benefits. This paper also studied some key problems of urban rail transit network planning, which include the combination of urban rail transit modes, the matching with feeder lines of other traffic modes, passenger forecasting, the relation between urban rail transit network scale and its performance, the spatial shape of urban rail transit network, etc.
