摘要：AbstractThis paper reveals the disadvantages in the current urban transportation models in China and proposes an integrated region- urban multimodal transportation model based on the traditional four step method. The model introduces a time allocation step, suggests better approaches in steps such as trip distribution and mode choice, and improves the connections among each model. This model framework incorporates the land use and transportation system, and is capable to evaluate the impact of land use and facility construction. Disaggregate travel behavior analysis is applied in the model for various steps to improve the accuracy in forecasting. The framework is suggested as a reference to improve the urban transportation model and integrate the urban planning and transportation planning closely.
