System Optimization-Based Model and Algorithm of Network Flow Assignment of Transport Hub

Transport hub is the critical node to achieve seamless transfer among different modes of transport, determining the efficiency of the city's passenger transport system. In review of the lack of quantitative basis for transport hub design and transport coordination problems and combined with characteristics of transport hub, the system optimization-based model of network flow assignment of transport hub is set up from the cost perspective to realize system optimization. Then the model is applied to an example, and is solved by genetic algorithm, and the results prove that there are important theoretical meaning and practical value of the study to provide quantitative basis for optimized design of transport hub.
