STATUS OF NCHRP RESEARCH ON THE SAFETY ASPECT OF STUDDED TIRES

THE NCHRP PROJECT 1-13(2), SCHEDULED FOR COMPLETION IN NOVEMBER 1972 WILL FORMULATE A PLAN FOR DETERMINING THE MAGNITUDE OF THE EFFECTS ON HIGHWAY SAFETY OF PAVEMENT WEAR AND LANE-MARKING WEAR BY STUDDED TIRES. THIS WILL BE AN INITIAL STEP IN EFFORTS TO QUANTIFY THE NONWINTER EFFECTS OF STUDDED TIRES. THE PROJECT WILL INCLUDE THE SYNTHESIZING OF ALL AVAILABLE KNOWLEDGE, QUALITATIVE MODELING OF THE EFFECTS AND THE PREPARATION OF EXPERIMENTAL QUANTITATIVE INFORMATION REQUIRED IN ASSESSING THE EFFECT OF STUDDED TIRES ON ACCIDENT FREQUENCY AND SEVERITY. ONE OF THE CONSIDERATIONS OF THIS PROJECT, WHICH IS SCHEDULED FOR COMPLETION IN LATE 1973, IS THE EXPOSURE OF VEHICLES WITH AND WITHOUT STUDDED TIRES TO ACCIDENT OCCURRENCE. MINNESOTA AND MICHIGAN HAVE MADE AVAILABLE DATA WHICH AS OBTAINED FROM VARIOUS SOURCES INCLUDING ACCIDENT RECORDS. MAGNETIC TAPE STORAGE, LICENSE AND VEHICLE REGISTRATION FILES AND QUESTIONNAIRE RETURNS. A BEFORE AND AFTER INVESTIGATION WAS POSSIBLE IN THE STUDIES WITH MINNESOTA DATA (WHICH WILL ADD MEASURABLY TO ITS VALUE). THE QUANTITY OF DATA AVAILABLE FOR ANALYSIS FAVORS AN EXPECTATION THAT MAJOR RESULTS CAN BE PRESENTED AT LEVELS NO LOWER THAN PERCENTAGE OF CHANGE. RESULTS THAT ARE REPORTED AT THE PERCENTAGE-OF-CHANGE LEVEL CAN BE USED IN ESTIMATING THE PROBABLE CHANGE IN ACCIDENT COST THAT CAN BE EXPECTED TO RESULT FROM THE BANNING OF STUDDED TIRES. STUDY OF MICHIGAN DATA INDICATE THAT THE FINAL RESULTS WILL SHOW A MINOR SAFETY ADVANTAGE FOR STUDDED TIRES.
