Abstract

The invention provides a data-driven early warning method for sudden large passenger flow at urban rail transit stations. Including: extracting minute-level time-domain signals of station passenger flow from multi-source AFC data, using minute-level time-domain signals to count sliding time window feature parameters that conform to the time-varying characteristics of passenger flow signals; training signal classifiers based on deep belief networks , extract the high-order hidden features of the passenger flow signal, and divide the passenger flow signal into an adaptive mode; calculate the local anomaly factor value of the passenger flow signal in the sliding time window according to the sliding time window characteristic parameters and the adaptive mode division result of the passenger flow signal, when the local anomaly factor When the value is greater than the set large passenger flow detection limit, a large passenger flow risk warning will be issued. The invention is driven by multi-source automatic fare collection data, can adapt to a dynamic incremental data environment, has the technical advantages of strong implementability and stable detection results, and provides scientific method support for urban rail transit passenger flow early warning.

Description

technical field [0001] The invention relates to the technical field of urban rail transit. More specifically, it relates to a data-driven early warning method for sudden large passenger flow at urban rail transit stations. Background technique [0002] With the continuous expansion of urban rail transit networks in major cities in my country, rail transit has become the backbone of urban comprehensive transportation systems, undertaking the task of meeting the diverse travel needs of passengers. The passenger flow demand of the urban rail transit system is significantly affected by external factors of the city, especially when large-scale cultural and sports activities, trade exhibitions, ground traffic control, and severe weather occur. When a sudden large passenger flow occurs, a large number of passengers flood into the station in a short period of time. If the warning is not given in time, it will cause overcrowding in the payment area of ​​the station, a sudden increas...
