Embodiment Construction

[0040] figure 1 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 1 As shown, 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. Afterwards, combined with the distribution of passenger flow in the same period of history, the full state of passenger flow is obtained through the deduction of passenger flow in the road network, and the affected passenger flow is screened out based on the information of emergencies. After the affected passenger flow is processed according to the redistribution rules, the passenger flow index is counted to obtain the final calculation result.

[0041] The method by which the system operates includes the steps of:

Abstract

The invention provides a passenger flow estimation system under the condition of urban rail road network emergency. A multi-factor influence impedance calculating method and an effective path calculating method are designed, so that a road network inter-OD multipath distribution ratio is acquired by a system; the passenger flow is loaded according to the distribution ratio; the full state of the passenger flow is acquired through the deduction of the passenger flow in the road network according to a historical passenger flow distribution law at the corresponding period; the influenced passenger flow is selected according to the information about the emergency; after the influenced passenger flow is processed according to a redistribution rule, a passenger flow index is counted and recorded, so that a final calculating result is acquired. According to the invention, the rail transit road network emergency processing capability is increased and the safety of the rail transit is ensured, so that the service level and quality of Chinese urban rail transit are greatly increased and the passenger flow estimation system is a beneficial measure for the life of people.

Description

technical field [0001] The invention relates to a passenger flow estimation system under the emergency condition of the urban rail network, in particular to a passenger flow impact analysis technology under the emergency condition of the 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 mor...
