Embodiment Construction

[0098] figure 1 It is the flow chart of passenger flow estimation method for the whole road network. By designing the impedance calculation method affected by multiple factors and the effective path calculation method, the multi-path distribution ratio between ODs in the road network is obtained, and the passenger flow is loaded according to the ratio. Then, combined with the passenger flow distribution law in the same period of history, the full state of passenger flow is obtained through the deduction of passenger flow in the road network.

[0099] figure 2 It is a flow chart of the passenger flow impact analysis method based on the historical passenger flow law when some sections of the road network are interrupted. Such as figure 2 shown, according to figure 1 The deduced passenger flow status is combined with the information of emergencies to screen out the affected passenger flow. After the affected passenger flow is processed according to the redistribution rules...

Abstract

The invention provides a passenger flow estimation method for an urban rail road network. By designing a multi-factor affected impedance calculation method and an effective path calculation method, a multi-path distribution ratio between OD (origin-destination) of the road network is obtained, and the passenger flow is loaded according to the ratio. By combining the historical corresponding period passenger flow distribution rule, the total state of the passenger flow is obtained by the deduction of the passenger flow in the road network. By accurately estimating the passenger flow volume of the road network, the safety of urban rail transit is ensured, so that the service level and quality of Chinese urban public transport are substantially improved, and the passenger flow estimation method is a useful measure in favor of people's livelihood.

Description

technical field [0001] The invention relates to a method for estimating the passenger flow of an urban rail network. Background technique [0002] With the growth of my country's urban rail transit mileage, the importance of its safe operation and emergency dispatch has become increasingly prominent. As the main undertaker of urban public transportation, the urban rail network system will cause large-scale accumulation of passenger flow in the event of section interruption and other emergencies, which will have a great impact on passenger transportation safety and service levels. Road network emergencies occur frequently. In order to rationally allocate transportation capacity and implement effective passenger transportation organization measures, it is necessary to grasp quantitative data such as the scope and impact of emergencies more quickly and accurately. [0003] At present, there is still a lack of a complete and systematic urban rail network passenger flow estimati...
