Comprehensive analysis of the influence of door width on the passenger flow time on Korean urban railways

Abstract

This paper deals with the effect of door width on the passenger flow time on Korean urban railways using analysis of covariance (ANCOVA) and regression analysis. All regression coefficients are statistically significant in both analyses. The ANCOVA results show that increasing the door width can be quite useful in reducing passenger flow time. Regression analysis, which controls for other independent variables, also shows a clear relationship between door width and passenger flow time. In an additional regression model, we consider the interaction between door width and the number of boarding passengers. This paper also compares flow times estimated through two different methods: laboratory experiments and live railway observation, and finds no significant difference between the two approaches.
