Possibility of Train Stop Position Errors at Stations by Railway Drivers

: Consideration Based on Driving Performance Data

Abstract

This study focuses on train stop position errors at stations and aims to evaluate the possibility of occurrence of delays in braking manipulations. Driving performance data from 118 drivers over a period of one year were analyzed. Logistic regression analysis was conducted to extract factors causing delays in braking manipulations and to calculate the possibility of occurrence of delays in braking manipulations. The objective variable was the experience of delays in braking manipulations during past two years. The explanatory variables included driving performance data, such as the ratio of using the maximum brake or the standard deviation of train velocity at 200 m before stopping, and driver attributes, including driving experience. The results showed that the experience of delays in braking manipulations were significantly associated with the ratio of using the maximum brake, ratio of using the neutral brake, standard deviation of train velocity at 200 m before stopping, and driving experience. The regression equation using these four explanatory variables was able to classify the experience of delays in braking manipulations by 79.0%.
