EFFECT OF AVERAGE SPEED AND VOLUME ON MOTOR-VEHICLE ACCIDENTS ON TWO-LANE TANGENTS
THE EFFECTS OF SPEED AND VOLUME ON THE ACCIDENT RATE NEED TO BE ANALYZED IN DETAIL. THIS SHOULD PROBABLY BE UNDERTAKEN SEPARATELY FOR TANGENT SECTIONS, CURVES, AND INTERSECTIONS, AND FOR ROADS OF VARIOUS NUMBERS OF LANES. THE PRESENT STUDY IS LIMITED TO TWO-LANE TANGENTS, BUT THE METHODS USED SHOULD BE APPLICABLE ALSO TO ACCIDENT ANALYSIS UNDER BROADER CONDITIONS. ACCIDENTS ARE DIVIDED INTO THREE TYPES: SINGLE- CAR, REAR-END, AND HEAD-ON. FOR EACH TYPE, A THEORY IS DEVELOPED RELATING ACCIDENT OCCURRENCE TO SPEED AND VOLUME OF TRAFFIC. THE THEORY IS THEN COMPARED WITH ACCIDENT EXPERIENCE ON A GROUP OF CALIFORNIA ROADS SELECTED FOR UNIFORMITY IN IMPORTANT FEATURES OF HIGHWAY CONDITION AND DESIGN. /AUTHOR/
