INVESTIGATION OF THE DYNAMIC IMPACT ON ROADSIDE OBSTACLES

EXPERIMENTAL AND THEORETICAL INVESTIGATIONS OF SINGLE-POST BASE-BENDING SIGNPOSTS ARE DISCUSSED. PREVIOUS ANALYTICAL WORK ON SIGNPOST COLLISION MECHANICS IS REVIEWED AND FOUND WANTING, AND APPROPRIATE EXTENSIONS AND REVISIONS ARE RECOMMENDED. PRELIMINARY FINDINGS FROM SIXTEEN FULL-SCALE SIGNPOST CRASH TESTS ARE PRESENTED, AND SPECIFIC DESIGN MODIFICATIONS INTENDED TO IMPROVE IMPACT PERFORMANCE ARE SUGGESTED. HIGH-SPEED CRASH TESTS TO EXAMINE THE FEASIBILITY OF FOAMED SODIUM SILICATE AS AN ENERGY ABSORPTION BARRIER MATERIAL ARE REPORTED. COMPUTER SIMULATIONS OF THE DYNAMIC RESPONSE OF VEHICLES IN TRAJECTORIES OVER EARTH MEDIAN DIKES ARE PRESENTED, AND CONCLUSIONS ARE DRAWN RELATIVE TO THEIR SENSITIVITY OF RESPONSE TO IMPORTANT DESIGN AND OPERATIONAL VARIABLES. /AUTHOR/
