Passenger Train Emergency Systems: Single-Level Commuter Rail Car Egress Experiments

Under Federal Railroad Administration (FRA) sponsorship, a series of three experimental egress trials was conducted in 2005 and 2006 to obtain human factors data relating to the amount of time necessary for individuals to exit from a passenger rail car. This final report describes the results of all these emergency egress experiment trials. To FRA’s knowledge, the 2005 commuter rail car egress experiment was the first time that U.S. passenger rail car egress time trials were conducted with commuter rail passengers as test participants. Controlled variables included egress from the commuter rail car using side door(s) to a high-platform, low-platform, or right-of-way location, or using an end door to an adjacent car; as well as lighting conditions. Participant egress times varied significantly by the number of passenger rail car exits used and the exit route taken. The collected exit-time data are intended for use in establishing passenger rail car egress time estimates/norms and evaluating various aspects of car design that may promote or impede prompt occupant egress. The experiment data will also be used as input for the development of a passenger rail car emergency egress simulation computer model that can predict emergency evacuation time for a variety of passenger rail car configurations.
