Abstract:With the urban renewal and the introduction of new line into high-speed railway hub, the railway hubs are also under pressure and demand for urban renewal. On the one hand, the traffic hubs are confronted with increasingly prominent traffic problems; on the other hand, the hubs also have more demands for the connection of new lines and urban renewal. Therefore, under the premise of existing supply-demand mismatch, the further conception and discussion are needed in terms of how to fully tap the potential within the existing space, such as restructuring the space of traffic facilities that are prone to congestion, like drop-off platforms, car parking garages, online car-hailing services, and taxi services, how to provide good services to attract passenger flow for public transportation facilities, and how to optimize the problems such as insufficient road scale and mismatch of grades in the distribution and convergence of road network.Taking North Xiamen Railway Station as the research object, based on the optimization framework of "spatial restructuring - process reengineering - mechanism innovation", the multiple traffic improvement measures are proposed to cover the individualized transportation, non-individualized transportation, and road network optimization. These schemes aim to alleviate the hub congestion and enhance the urban competitiveness at the lowest possible cost and with the greatest possible efficiency improvement within a limited space in the context of urban renewal, which is of great significance for solving the traffic problems at North Xiamen Railway Station and also provides a reference example for the optimization of transportation hubs in other cities.
