SAFETY BARRIERS FOR MOTORWAYS: SHOULDER AND BRIDGE BARRIERS AND IMPACT ATTENUATORS SURVEYED AND ASSESSED

The various types and practical qualities of deformable and non-deformable safety barriers are listed. The main conclusions drawn from tests based on several safety criteria are: various types of deformable barriers (steel guide rails) perform well when hit by cars; various types of these barriers perform satisfactorily when hit by rather heavy vehicles; non-deformable (concrete) barriers give reasonable protection to cars only when the impact conditions are not too severe; rigid barriers perform better than easy deformable ones when hit by heavy vehicles; the way non-deformable barriers perform seems to be more dependent on weather conditions than is the case with deformable barriers.
