一种居住区位和通勤交通方式的组合选择模型

Hybrid selection model for residential location and traffic communication modes

为了研究通勤交通方式对就业者选择居住区位的影响,基于交叉分层的Logit模型建立了居住区位和通勤交通方式的组合选择模型。以不同通勤距离为半径作居住区位选择环域集,以通勤交通方式和居住区位的两两组合为模型选择项集合,以就业者社会经济属性、居住成本、通勤成本为特征变量建立概率选择模型。根据调查数据,采用阶段计算法对特征变量和模型参数进行标定和检验。测试结果表明:通勤时间、通勤费用和居住成本与选择项关系密切;收入较高且拥有小汽车的就业者对于居住区位选择的灵活性较大。

In order to research the effects of communication modes on residential location selection,this paper established a hybrid selection model of communication modes and residential location based on cross-nested Logit model.Taking ring fields with different commuting distance to be radius as residential location selection set,taking combination of two of commuting modes and residential location as model alternative set,taking social-economic attitude,housing costs and commuting costs of employees as characteristic variables,this paper constructed the probability choice model.By the survey data,the model employed stage calculation method to calibrate and test characteristic variables and model parameters.The result shows that commuting time,commuting cost and residential cost are the important factors with the selection model,and employees with higher incomes and cars are more flexible to residential location selection
