Abstract

The University of Virginia Center for Rail Safety-Critical Excellence (CRSCE) has developed a questionnaire for measuring railroad engineers’ beliefs regarding the frequency of unusual action decisions based upon scenarios encountered during a daily work schedule. The questionnaire is designed to collect responses via a secure web-based interface. Scenarios describe railroad conditions such as work zones, temporary speed restricted zones, control point signal aspects, and emergency braking. Engineers are given the correct response according to rulebook regulations. Given these conditions, engineers are asked to rate the frequency of unusual action decisions of a hypothetical crew, based upon performance-shaping factors of fatigue, broad and specific ex
