Problems solved by technology
[0002] At present, large-scale passenger transport hubs only carry out optimization research on capacity matching between a single mode of transportation or two modes of transport, and there is almost no research on capacity matching between three or more modes of transport
Moreover, most of the studies on the matching optimization of distribution transportation capacity in large-scale passenger transport hubs focus on railway passenger transport hubs. However, different passenger transport hubs have differences in passenger composition, travel characteristics, and travel demand. very scarce
[0003] Large-scale passenger transport hubs are nodes connected by multiple modes of transportation. Existing researches often seldom consider the competition and cooperation among various modes of transportation, and ignore the interaction among multiple modes of transportation. Therefore, it is urgent to develop a The method of unifying the transportation subsystem as a whole to optimize the allocation of transportation resources

The invention provides a transport capacity matching method for multiple transport modes of a passenger transport hub based on double-layer planning. The method comprises the following steps: establishing a specific expression of a generalized cost function of each traffic mode of the passenger transport hub; constructing a double-layer planning model of passenger transport hub multi-traffic-modetransport capacity matching, the double-layer planning model comprising an upper-layer sub-model and a lower-layer sub-model, the upper-layer sub-model adjusting departure intervals of buses and railtransit lines and the serviceable number of taxies in unit time, and the lower-layer sub-model providing passenger flow distribution results for the upper-layer sub-model; and solving the double-layerplanning model based on a genetic algorithm and an MSA algorithm, and outputting an individual with the maximum fitness function value as a solving result of the double-layer planning model. The transport capacities of rail transit, buses and taxies are accurately matched according to passenger demands of the passenger transport hub, the transport capacity utilization rate of all transport modesof the passenger transport hub is increased, the overall collecting and distributing efficiency of a land side transport system is improved, and the passenger transfer experience is improved.
Description
technical field [0001] The invention relates to the technical field of traffic operation management, in particular to a capacity matching method for multi-traffic modes of passenger transport hubs based on bi-level planning. Background technique [0002] At present, large-scale passenger transport hubs only carry out optimization research on capacity matching between a single mode of transportation or two modes of transport, and there is almost no research on capacity matching between three or more modes of transport. Moreover, most of the studies on the matching optimization of distribution transportation capacity in large-scale passenger transport hubs focus on railway passenger transport hubs. However, different passenger transport hubs have differences in passenger composition, travel characteristics, and travel demand. very scarce. [0003] Large-scale passenger transport hubs are nodes connected by multiple modes of transportation. Existing researches often seldom con...
