Method and system for simulating calculation of transport capacity of urban rail transit network

Abstract

The invention discloses a method and a system for simulating calculation of transport capacity of an urban rail transit network. The method includes the following steps: setting a simulation scene which includes network features, passenger flow features and a running chart; loading initial passenger flow generation quantity into a network; starting to simulate; calculating and outputting service levels of all lines and all stations; judging whether the service levels meet conditions for calculation stopping or not, if yes, displaying current total passenger flow quantity; and if not, adding added passenger flow into the network, then repeatedly executing simulation starting. The system comprises a scene setting module, an initializing module, a service level calculating module, a stopping condition judging module, a pressure adding module, a displaying module and a simulating module. By adopting the idea of pressure testing, using computer simulation as a means and taking the network service level into consideration, calculation quantity is reduced, and reliability of calculation results is improved.

Description

technical field [0001] The invention relates to a simulation calculation method for urban rail traffic. More specifically, the present invention relates to a simulation calculation method and system for urban rail transit network transportation capacity. Background technique [0002] At present, there are few methods for calculating the transport capacity of urban rail transit network at home and abroad, mainly based on the calculation of line capacity, without considering the overall perspective of the road network. [0003] Among the existing calculation methods, the calculation of road network transportation capacity is mainly based on graphical method and analytical calculation method. The graphical method is a method to determine the road network transportation capacity by drawing train diagrams through computer or manual simulation of the actual situation of transportation production. This method is more intuitive, but the amount of calculation is large, the calculati...

Problems solved by technology

Because only from an objective point of view, the road network system can increase the number of passengers transported, but from the subjective point of view of passengers, the degree of congestion has reached the limit of its tolerance, and other passengers can no longer enter the system

However, other methods have not considered the service level requirements when calculating the road network transport capacity, so the reliability of the calculation results is low
