RAILROAD GRADE CROSSING PASSIVE SIGNING STUDY
The study examines the effectiveness of new passive signing configurations in warning drivers of the potential hazards at railroad grade crossings. Experiments were conducted in two phases over a two-year period. The first phase was begun in March 1975 and evaluated seven sign configurations at five test sites in Ohio and one site in Maine. The purpose of Phase I was to determine at a few crossings whether any of the new signs showed promise of being more effective than the existing sign configuration and to evaluate a variety of experimental variables. The results of Phase I were previously reported and indicated improved effectiveness for the new signs tested. The purpose of Phase II was to test and verify at a national level (18 sites in 14 states) the most effective signs as determined from Phase I and to concentrate on and refine, if necessary, the most important variables. In each phase, before-and-after data were collected at each site so that relative improvements provided by the new signs could be determined. The results of Phase II confirmed the findings of Phase I in that drivers showed more awareness (that is, an increased percentage of headmovements or looking for trains) with the new signs at the crossings tested.
