THIS PAPER DEVELOPS PROCEDURES TO EVALUATE ACCIDENT POTENTIALS AND TO SPECIFY MINIMUM PROTECTIVE DEVICES FOR RURAL GRADE CROSSINGS. FOUR VARIABLES--RELATIVE EXPOSURE TO POTENTIAL COLLISIONS, DRIVER DISTRACTION, TYPE OF PROTECTIVE DEVICE, MINIMUM SIGHT RATIO--ARE BASED ON READILY OBTAINABLE FIELD DATA. A GRAPH IS PROVIDED TO AID JUDGEMENT IN SELECTING A MAXIMUM TOLERABLE ACCIDENT PRONE PROBABILITY (PROBABILITY OF UNDERPROTECTION). WITH THE USE OF THE NOMOGRAPH AND DESIGN CHARTS THE POTENTIAL HAZARD AND MINIMUM PROTECTIVE DEVICE MAY BE DETERMINED FOR EACH CROSSING. A RANK ORDERING OF POTENTIAL HAZARDS PROVIDES PRIORITY RATINGS FOR SCHEDULING IMPROVEMENTS. AN EXAMPLE IS PROVIDED, USING FIVE RURAL GRADE CROSSINGS.
