ACQUISITION OF INFORMATION ON EXPOSURE AND NON-FATAL CRASHES (PHASE I). SECOND INTERIM REPORT
THE PRIMARY MEASURE OF EXPOSURE IS THE QUANTITY "VEHICLE- MILES TRAVELLED" BY VARIOUS DRIVER-VEHICLE COMBINATIONS IN VARIOUS ROADWAY-ENVIRONMENT COMBINATIONS. OTHER METHODS PROVIDE A DIRECT INDICATION OF THE QUANTITY AND/OR INTENSITY OF HIGHWAY DRIVING PATTERNS, E.G., DRIVING TIME, TRAFFIC VOLUME, NUMBERS OF REGISTERED VEHICLES OR LICENSED DRIVERS, GASOLINE CONSUMPTION BY MOTOR VEHICLES. ALL OF THESE MEASURES ARE INTENDED TO REPRESENT DRIVING EXPOSURE AS EXPOSURE TO THE RISK OF TRAFFIC ACCIDENTS. DIFFERENT TYPES OF DRIVERS TEND TO DRIVE NOTICEABLY DIFFERENT DISTANCES ON THE AVERAGE, CERTAIN KINDS OF VEHICLES TRAVEL MORE THAN OTHERS, CERTAIN KINDS OF ROADS CARRY MORE TRAFFIC THAN OTHERS, AND CERTAIN ENVIRONMENTS PRODUCE MORE MILEAGE THAN OTHERS. THEREFORE, IT IS APPROPRIATE TO CONSIDER THE DIFFERENCES IN EXPOSURE (VEHICLE MILES) AMONG DIFFERENT CLASSES OF DRIVERS, VEHICLES, ROADS, AND ENVIRONMENTS. /HSRI/
