Measuring Train Driver Performance as Key to Approval of Driverless Trains
It provides a dataset for research, standardization, and regulation in the domain of autonomous train safety, but is incremental as it focuses on data collection rather than novel methods.
This paper addresses the challenge of quantifying train driver performance in obstacle detection for safety approval of driverless trains by summarizing existing data and providing a new public dataset of 711 measurements from controlled experiments, including reaction times and distances under various conditions.
Points 2.1.4(b), 2.4.2(b) and 2.4.3(b) in Annex I of Implementing Regulation (EU) No. 402/2013 allow a simplified approach for the safety approval of computer vision systems for driverless trains, if they have 'similar' functions and interfaces as the replaced human driver. The human driver is not replaced one-to-one by a technical system - only a limited set of cognitive functions are replaced. However, performance in the most challenging function, obstacle detection, is difficult to quantify due to the deficiency of published measurement results. This article summarizes the data published so far. This article also goes a long way to remedy this situation by providing a new public and anonymized dataset of 711 train driver performance measurements from controlled experiments. The measurements are made for different speeds, obstacle sizes, train protection systems and obstacle color contrasts respectively. The measured values are reaction time and distance to the obstacle. The goal of this paper is an unbiased and exhaustive description of the presented dataset for research, standardization and regulation. The dataset with supplementing information and literature is published on https://data.fid-move.de/de/dataset/atosensedata
