摘　　要：针对出行生成预测中变量众多以及多重相关性问题,以常州调查数据为样本,分别采用逐步回归分析方法和偏最小二乘回归(PLSR)方法,建立基于土地利用形态的交通发生量模型。并对两者建模方法进行分析比较,结果表明PLSR能有效地解决变量多重相关性问题,模型意义清晰,效果显著。There are serious multiple correlations of the urban land-use parameters which are the independent variables in the study of the relationships between land-use and traffic generation. The problem of multiple correlations of parameters is difficult to be solved by ordinary regression analysis methods. Taking the investigated parameters of traffic generation and land-use form of Changzhou city as a sample, this paper used partial least square regression （PLSR） and stepwise regression methods to establish the traffic generation model in combination with land-use form. Comparison between the two methods shows that the PLSR method is effective and reliable to solve the problem of multiple correlations of parameters and has clear physical meaning.
