Interaction Mechanism and Coupling Theory of Transit-oriented Multimodal Urban Traffic Systems

Abstract：Based on the capacity and activity-travel behavior study of transit-oriented traffic network， this project has revealed the interactions among bus network， metro network and road network， and has established the coupling theory among those multimodal networks. In general， those studies can be divided into three levels： transit-oriented multimodal demand and supply， multi-typed interactions between different networks and efficiency evaluation of those networks. Firstly， investigations were conducted based on understandings of activity-travel behavior under transit-oriented traffic network and related database was established. Models like identification model for bus travel behavior， Bayesian network model for bus service level and multimodal utility model were built based on those data to provide comprehensive understanding of multiple and complex travel demand； then， impacts of multimodal networks on traffic flow were studies based on the understanding of operating characteristics and capacity of urban ground transit network. A methodology towards more integrated ground and underground transit and traffic flow transfer models between those networks were established. Furthermore， a deep study on coupling theories between trip distribution and transit-oriented networks as well as coupling theory among different transit network， help to form the utilized mechanisms for level configuration， network layout and ground transportation network transfer facility towards multimodal transit network. Base on that， finally， a differentiated evaluation index system for both macro and micro-level of transit-oriented networks was established， including varies of factors like travel efficiency， public transportation capacity， emissions and energy consumption and construction costs， et al. and a multimodal transportation network performance analysis empirical platform was established， providing bus priority strategy based on vehicle traffic and social efficiency evaluation and feedback mechanism based on the visualized distribution of pollutant concentration based on MATLAB. Those findings can be used as basis to utilize transportation structures as well as saving energy.

Keywords：Transit-oriented；multimodal transportation network；coupling theory
