基于低碳导向的多模式公交网络鲁棒性优化建模

On the background of low-carbon transportation，taking multi-modal public transport systems as the research object and the robustness of the system as the key factor, this project will study on the optimization modeling approach of multimodal public transport, including the transit network design and operation system. Firstly, multi-modal transit network is abstracted as complex networks in order to analyze the mechanism of network topology impacts on carbon emissions and the robustness of the bus system. Then with emulation and characteristic parameters, determine the best network topology and its characteristic parameter values with minimum carbon emissions and the optimal robustness under different bus demand conditions. Within the framework of the optimal network topology, complex network theory is applied to establish optimization and generation model for multi-modal transit network considering low carbon and robustness. Based on the operation robustness research on single transit model, systems engineering principles is applied to establish multi-modal transit network operation robust optimization mode with low-carbon constraints. This study can enrich urban public transit planning theory system, and provides a set of targeted models and methods which can build a diversified public transport mode. Therefore it has high theoretical value and practical significances.
