基于平均换乘的城市公交线网性能评价

评价公交线网性能的指标有多种,其中交通网络的可达性指标是交通系统能否优质、高效完成运输任务的一项综合性评价指标,而平均换乘次数则能很好地反映这一指标．通过依次计算“公交n次换乘矩阵”的方法求出网络平均换乘次数,并根据平均换乘次数对公交线网的结构性能进行评价．

Public-transit Evaluation Based on Average Transfer Times

Many indexes can be used to evaluate the public-transit performance. Of them, the accessibility of public-transit is a synthetical index which decides whether the transportation system can work with high quality and efficiency, and it can be reflected by average transfer times(ATT) .In this paper,a new way is given which is based on ATT that can be gained by calculating "public transfer matrix n times" in turns to evaluate the performance of public-transit .
