摘　　要：带状城市具有纵向长、横向窄的特点,易形成城市“瓶颈”从而造成交通拥堵。为进一步明确轨道交通对带状城市交通瓶颈的优化效果,采用交通现状调查数据分析及未来交通预测相结合的方法,得到构建轨道交通前后的交通出行特征值。研究表明,沿带状城市轴线构建的骨干轨道交通不仅可承担主要交通输送,还对未来交通具有优化作用,主要表现在:(1)轨道交通可优化居民的出行结构,引导居民绿色公交出行;(2)在出行距离增加,客流量剧增的情况下,为居民出行提供更好可达性,缩短出行时间。The longitudinal traffic corridor in belt-shape cities is long and the transverse width is narrow which may cause traffic congestion.In this paper,using the method of combining data analysis of traffic status survey and future traffic forecast,the characteristic values of traffic trips before and after the construction of rail transit were compared.The result shows that,the linear rail transit along the axis for belt-shape cities could undertake major transportation,and optimize future transportation.It is mainly manifested in strengthening and guiding green bus travel,improving residents travel accessibility,and significantly improving the congestion of major urban roads.
