土地利用与居民出行生成模型及其参数标定

Land use and resident trip generation model and its parameter calibration

基于城市交通与土地利用的相互关系,建立了土地利用与居民出行生成模型,并对模型中的参数进行了标定。由于不同的土地利用类型,居民出行生成量有很大的差异,选用建筑容积率并利用MATLAB软件计算其对土地利用类型赋予的不同的权重系数,并以长春市为例对模型的参数进行标定并加以验证。

Based on the interaction between the land utilization and the urban traffic, a land utilization and resident trip generation model was established and its parameters were calibrated. Different types of the land utilization make different trip volumes generated by the residents, in order to take this difference into account, all types of the land utilization were characterized by the land area to floor area ratios which were endowed with corresponding weight factors and calibrated by the software MATLAB. The parameters of the established model were verified with the field data and their statistical analysis from Changchun city and the result was positire.
