Correlation analysis of platform intelligent electric screen doors and accidents in urban rail transit

Abstract

In order to determine the main factors affecting the accident of passenger falling off the track, 223 cases of subway station passengers falling off the track in mainland China from 2000 to 2020 (up to September) were collected as the research object. Among them, 13% of the samples had platform screen doors, and 87% had no platform screen doors. Considering the limitations of the statistical sample data, in order to accurately and scientifically study and judge the effectiveness of PSD in reducing the accident of passengers falling off the track, this paper uses the knowledge of advanced mathematics and statistics, combined with the passenger volume information of the station, to analyse and verify the relationship between the existence of PSD and the occurrence of the accident. The statistical results of the case show that the installation of platform screen doors in the station can reduce the occurrence of passenger falling off the rail to a certain extent. The mathematical analysis shows that the correlation between the installation of platform screen doors in the station and the passenger falling off the rail in the operation process of Urban Rail Transit reaches 0.99, which is consistent with the statistical results of this case.
