Second train coming warning sign demonstration project Khawani, Vijay

By: Khawani, VijayPublication details: Transportation Research Record, 2001Description: nr 1762, s. 32-6Subject(s): USA | Level crossing | Warning | Train | Two | Demonstration project | In situ | Pedestrian | Accident prevention | Campaign | Attention | | Efficiency | Behaviour | Video camera | Comprehension | J06 | 841 | 22Bibl.nr: VTI P8167:1762Location: Abstract: Data collected to date for a demonstration project on the Los Angeles County Metropolitan Transportation Authority's (LACMTA's) Metro Blue Line (MBL) are presented. The project involves the installation of a train-activated sign to warn pedestrians when two or more trains are approaching a highway-rail intersection (HRI). The hazard associated with two trains approaching an HRI is particularly prevalent if the HRI is adjacent to a station. Typically, if pedestrians see a train berthed at a station that has activated warning devices downstream, in a haste to board the train, they fail to notice trains approaching from the opposite direction on adjacent tracks. This scenario has resulted in 14 accidents and 4 fatalities at LACMTA's Vernon Avenue HRI since the start of MBL operations in 1990. A second train approaching the HRI can reasonably be assumed to be a major contributing factor in many of such train-pedestrian collisions. The process for selecting the demonstration site and warning sign is described. Also described are the sign's detail, public information plan to educate and inform pedestrians about the sign, and method to evaluate sign effectiveness. Because the project is under way, final results on sign effectiveness cannot be presented, but data collected and projected final results are discussed.
