CORRELATES OF 30-MPH INTERSECTION COLLISIONS

TWO AUTOMOBILE INTERSECTION COLLISION EXPERIMENTS WERE CONDUCTED UNDER IDENTICAL CRASH CONDITIONS TO EVALUATE DATA REPRODUCIBILITY AND PROVIDE A BASIS FOR STUDYING PERFORMANCE DIFFERENCES ACCOMPANYING CHANGES IN IMPORTANT SUBVARIABLES. STUDIES WERE MADE OF COLLISION PERFORMANCE AS A FUNCTION OF WHETHER THE CARS HAD BEEN INVOLVED IN A PREVIOUS, MORE SEVERE IMPACT. COMPARISON OF VEHICLE DYNAMICS, SKID AND DEBRIS PATTERNS, DAMAGE PATTERNS, AND COST TO REPAIR IS PROVIDED. AVERAGE COEFFICIENTS OF FRICTION OPERATING DURING SPECIFIC POSTCONTACT SPIN-OUT TRAJECTORIES OF VEHICLES WERE CALCULATED, AND RELATED FINDINGS DISCUSSED. IN ADDITION, THE DIFFERENCE BETWEEN LAMINATED AND TEMPERED SIDE-WINDOW GLASS FOR THE STRUCK CAR WAS EVALUATED FOR THIS PARTICULAR COLLISION EXPOSURE. TRIAXIAL ACCELEROMETERS, MOUNTED IN THE HEADS AND CHESTS OF ANTHROPOMETRIC DUMMIES, SAFETY BELT TENSIOMETERS AND HIGH -SPEED PHOTOGRAPHY PROVIDED THE PRINCIPAL SOURCE OF RECORDED DATA. AN IBM 7090 COMPUTER FACILITATED DATA REDUCTION. THE RELATIVE PERFORMANCES OF LAP BELT VS COMBINATION SHOULDER AND LAP BELTS WERE STUDIED FOR SIMULATED ADULT MOTORISTS; CHILD AND INFANT DUMMIES WERE USED TO EVALUATE SPECIAL RESTRAINING DEVICES.
