摘    要:如何正确判定城市客运交通走廊是进行城市大运量客运交通方式规划首先需要解决的问题。通过分析城市客运交通走廊对交通源和交通方式的集聚效应特点,提出采用效应场和场中介质的概念来模拟交通走廊对交通流和交通源的吸引作用。应用衰减函数或磁感函数作为效应场函数模拟分析城市客运交通走廊对附近范围产生的集聚效应,采用人口密度、出行生成密度或潜力密度作为介质函数来表现走廊附近范围的土地利用形态,提出了一种直接根据用地来确定城市客运交通走廊的方法。

关 键 词:城市客运交通走廊  集聚效应  衰减函数  磁感函数

Abstract:How to identify urban passenger corridor is the principal issue in urban rail transportation lines planning.Based on analyzing the characteristics of clustering effect caused by urban passenger corridor,the concepts of effect field and medium are applied to simulate the attractive effect of the corridor on travel origins and modes.The attenuation function or magnetic induction function is used as field function,which reflects clustering effect around the corridor.The population density,trip generation density or potential density is served as medium function,reflecting the land use around the corridor.According to the field function and medium function,a method to identify urban passenger traffic corridor is brought forward,which is directly based on land use.
Keywords:urban passenger corridor  clustering effect  attenuation function  magnetic induction function
