Mainline Automatic Train Horn and Brake Performance Metric
Rustam Tagiew
This paper argues for the introduction of a mainline rail-oriented
performance metric for driver-replacing on-board perception systems. Perception
at the head of a train is divided into several subfunctions. This article
presents a preliminary submetric for the obstacle detection subfunction. To the
best of the author's knowledge, no other such proposal for obstacle detection
exists. A set of submetrics for the subfunctions should facilitate the
comparison of perception systems among each other and guide the measurement of
human driver performance. It should also be useful for a standardized
prediction of the number of accidents for a given perception system in a given
operational design domain. In particular, for the proposal of the obstacle
detection submetric, the professional readership is invited to provide their
feedback and quantitative information to the author. The analysis results of
the feedback will be published separately later.
