A METHOD OF RATING GRADE CROSSINGS IN TERMS OF SIGHT DISTANCE HAZARDS WAS DEVELOPED. THIS SIGHT DISTANCE RATING WAS COMBINED WITH THE P.R.A. FORMULA IN A "SPECIAL RATING" WHICH GAVE SLIGHTLY MORE SIGNIFICANT RESULTS WHEN APPLIED TO THE CROSSING RECORD. ALTHOUGH NOT SATISFACTORY THE LIST OF CROSSINGS HAS BEEN RATED FOR AID IN PLANNING A PROGRAM OF CROSSING PROTECTION AND ELIMINATION. LACKING IS ANY INFORMATION ON THE TYPE OF PROTECTIVE INSTALLATION THAT COULD BE CONSIDERED MOST EFFECTIVE FOR THE DIFFERENT RATINGS. NO SIGNIFICANT CORRELATION WAS FOUND BETWEEN ACCIDENT RECORDS AND NUMBER OF TRAIN MOVEMENTS, VOLUME OF HIGHWAY TRAFFIC, NUMBER OF RAILROAD TRACKS OR CLEAR VIEW DISTANCE. /AUTHOR/
