Samenvatting
Full-scale dynamic tests were made of 15 proposed designs of traffic barriers for use in median areas. Of these, two proved to be worthy of trial installations. This report describes the procedure used in testing median barriers by oblique, high-speed collisions with passenger vehicles and a 17,000-lb bus, and outlines the extensive instrumentation used in this test series. Specific recommendations are made for use of a flexible-type barrier in wide medians and a semi-rigid type in narrow medians. /author/.
