CRASH TESTS AND EVALUATION OF SINGLE POST HIGHWAY SIGNS

SEVENTEEN FULL-SCALE VEHICLE CRASH TESTS WERE CONDUCTED TO EVALUATE SINGLE POST ROADSIDE SIGNS SUCH AS MILE MARKERS, ROUTE MARKERS, DESTINATION, STOP, AND ONE WAY SIGNS. SOME OF THE SIGNS WERE EQUIPPED WITH BREADAWAY DEVICES SUCH AS THREADED PIPE COUPLINGS AND MULTI-DIRECTIONAL SLIP BASES. OTHER SIGNS WERE MOUNTED ON DELINEATOR POSTS AND SMALL DIAMETER PIPE WHICH BENT DOWN ON VEHICLE IMPACT. THE TEST VEHICLES WERE TOWED INTO THE SIGNS AT NOMINAL IMPACT SPEEDS OF 30, 45 AND 60 MPH. RECOMMENDATIONS ARE MADE TO MINIMIZE OR ELIMINATE SOME POTENTIALLY HAZARDOUS SECONDARY COLLISIONS OF THE SIGNS WITH THE VEHICLE'S WINDSHIELD AND ROOF.
