SPOTTING SKID-PRONE SITES ON WEST VIRGINIA HIGHWAYS
THIS PAPER DESCRIBES THE SYSTEM DEVELOPED BY THE WEST VIRGINIA DEPARTMENT OF HIGHWAYS FOR IDENTIFYING SKID-PRONE SITES, DETERMINING FOR EACH THE DIFFERENTIAL BETWEEN THE ACTUAL SKID NUMBER AND THE REQUIRED SKID NUMBER, PROGRAMMING FOR REMEDIAL MEASURES IN SKID RESISTANCE (INCLUDING RESURFACING, CHANGES IN SUPERELEVATION, AND DRAINAGE), AND EVALUATING OTHER FEATURES RELATED TO CAUSE OF SKID, SUCH AS ALIGNMENT, SIGHT DISTANCE, AND CONDITION OF PAVEMENT AND SHOULDER. RELATIONSHIPS BETWEEN RATES OF ACCIDENTS IN WEST VIRGINIA ON WET AND DRY PAVEMENTS AND VARIOUS GEOMETRICS WERE DETERMINED. SIX PAGES OF APPENDIX ARE DEVOTED TO FORMULAS FOR CALCULATING SKID NUMBER AND THE SKID NUMBER NEEDED AT AN INTERSECTION IN TERMS OF DECELERATION RATES AND CENTRIFUGAL FORCE. IT IS ASSUMED THAT, BECAUSE OF ANNUAL FLUCTUATION IN SMALL SAMPLES, A REPORTED NUMBER OF THREE ACCIDENTS AT A SITE PER YEAR CAN BE REDUCED BY AT LEAST ONE OR MORE PER YEAR, THUS MAKING A $2,000 INVESTMENT IN ANTI-SKID MEASURES FOR SUCH A SITE (THE APPROXIMATE COST OF TREATING INTERSECTION APPROACHES) A WORTHWHILE INVESTMENT.
