CONSTRUCTION ZONE, DETOUR AND TEMPORARY CONNECTION ACCIDENTS

CONSTRUCTION ZONES, DETOURS, AND TEMPORARY CONNECTIONS USUALLY INCLUDE GEOMETRIC FEATURES AND ROADWAY ENVIRONMENTS WHICH REQUIRE MORE CAUTION ON THE PART OF THE MOTORIST THAN NORMAL HIGHWAY TRAVEL. SPECIAL CARE IN THE DESIGN OF CONSTRUCTION ZONES, IN THE USE OF DELINEATION AND WARNING DEVICES, AND IN THE CONTROL OF CONTRACTOR'S OPERATIONS IS NECESSARY TO MINIMIZE THE IMPACT OF THE CONSTRUCTION OPERATION ON SAFETY. TWO STUDIES WERE MADE OF CONSTRUCTION ZONES TO COMPARE THE ACCIDENT RATE DURING CONSTRUCTION WITH THE RATE FOR THE SAME PORTION OF HIGHWAY PRIOR TO CONSTRUCTION. THE FIRST STUDY IN 1965 SHOWED THAT THERE WAS A SIGNIFICANT INCREASE IN ACCIDENTS DUE TO THE CONSTRUCTION ZONE. THE SECOND STUDY IN 1970 DEMONSTRATED THAT THE IMPROVED STANDARDS AND PRACTICES NOW IN EFFECT HAVE REDUCED THE CONSTRUCTION ZONE ACCIDENT RATE TO A RATE COMPARABLE WITH THE RATE PRIOR TO THE BEGINNING OF CONSTRUCTION. APPENDIX I IS A SECTION FROM THE CALIFORNIA CONSTRUCTION MANUAL REGARDING TRAFFIC HANDLING DURING CONSTRUCTION. /AUTHOR/
