Analysis of railroad-highway crossing active advance warning devices
BL Bowman - Transportation research record, 1987 - safetylit.org
The purpose of this study was to determine which one of three candidate active advance
warning devices for use on roadway approaches to rail-highway crossings was the most
effective. Each of the candidate devices, developed during a previous study, consisted of a
primary message sign, a supplementary, WATCH FOR TRAINS message plate, and two 8-
in. amber, alternately flashing beacons. The devices differed only in the configuration and
message of the primary sign. The study was conducted at four sites where sight restrictions …
