EFFECT OF SHOULDER WIDTH ON ACCIDENTS ON TWO-LANE TANGENTS

CALIFORNIA ACCIDENT RECORDS FOR 1948 WERE EXAMINED FOR THE RELATION BETWEEN SHOULDER WIDTH AND ACCIDENT OCCURRENCE ON TWO-LANE TANGENTS. FOR SIMILAR TRAFFIC VOLUMES, SHOULDERS 6 FEET WIDE WERE SAFER THAN NARROWER SHOULDERS AND, ALSO, (AT VOLUMES OVER 5,000 VEHICLES PER DAY) SAFER THAN WIDER SHOULDERS. /AUTHOR/
