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
