Urban railway choice behavior model based on RP data and SP data

The inconsistence of SP data between behavior and behavior intention is a serious problem. The article introduces the method of revises the SP data using the RP data. Then take Beijing as the example, establishes the RP data models, the SP data model and the fusion data model, it carries on the analysis of model sensitivity. The results indicate: the mark of expense parameter is not logical in the RP data mode; The precision of SP data model is high, but the effects of some parameters are not remarkable; The fusion data model parameters' test are remarkable, the model elasticity is small, and its' sensitivity is deactivated.
