Problems solved by technology

In recent years, video recognition technology has developed rapidly, and the recognition of large passenger flow based on video recognition technology has become a major development direction. Although the current video recognition technology has matured to recognize the number of people, how to complete the operation analysis of large passenger flow in subway stations based on the number of people obtained in real time Rapid assessment remains a current pain point

Embodiment 1

[0031] A risk assessment method for large passenger flow operations in subway stations, the steps of which are as follows figure 1 As shown (this example takes Xujingdong subway station passenger flow data as an example):

[0032] (1) Confirmation of passenger flow bottleneck points, characteristic day types, and characteristic time period types in subway stations, as follows:

[0033] Divide the bottleneck points of East Xujing Subway Station into 8 types: security inspection machines, gates, escalators, passages, platforms, station halls, entrances and exits, and ticket offices. Among them, escalators are the third type of bottleneck points, which are divided according to the passenger flow characteristics of the station On characteristic days (such as normal working days, normal weekends and major holidays), combined with the calculation of the traffic capacity of various facilities on the pedestrian traffic flow in the station and on-site observation results, determine the...

Embodiment 2

[0074] An electronic device, including one or more processors, one or more memories, one or more programs and real-time monitoring and identification video equipment for real-time monitoring of passenger flow density at various bottleneck points in a subway station;

[0075] One or more programs are stored in the memory, and when the one or more programs are executed by the processor, the electronic device executes the risk assessment method for large passenger flow operation of a subway station as described in Embodiment 1.

Abstract

The invention discloses a subway station large passenger flow operation risk evaluation method and application thereof. The method comprises the steps of monitoring and identifying passenger flow density of various bottleneck points in a subway station in real time, and determining a passenger flow density grade and an operation risk occurrence severity index Si according to the passenger flow density of the ith type of bottleneck points at the moment; and counting the duration of the ith bottleneck point at the passenger flow density level, determining the level of the ith bottleneck point and an operation risk occurrence possibility index Li, then solving an operation risk level index Ri of the ith bottleneck point based on Ri = Si * Li, and finally, considering the weight coefficient alpha i of each bottleneck point and solving an overall operation risk level index R of the station according to R = sigma iRi * alpha i. Quantitative evaluation of the large passenger flow operation risk of the subway station is achieved, and the method has certain self-evolutionary property, has the characteristics of low cost, fast evaluation process and good adaptability, and has great application prospect.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit intelligent passenger transport management, and relates to a method for evaluating the operation risk of a large passenger flow in a subway station and its application, in particular to a method for evaluating the risk of operating a large passenger flow in a subway station based on video recognition technology and its application. Background technique [0002] With the rapid development of the economy, the scale of the urban rail transit network continues to expand, and the subway plays an increasing proportion in the means of transportation that people travel, and the passenger volume it carries is also increasing. However, with the rapid development of urban rail transit, there are also problems such as unsmooth passenger flow organization at stations and mismatched line traffic plans. Especially during peak hours, the large passenger flow not only reduces the travel efficiency and c...
