They are designed to redirect vehicles, reduce the severity of run-off-road crashes, and protect motorists from roadside hazards such as steep slopes, fixed objects, bridges, and opposing traffic. However, not all highway guardrails are manufactured or evaluated according to the same requirements. Different markets use different standards and testing systems to determine whether a road safety barrier is suitable for a particular application. Among the most widely referenced standards are EN 1317 in Europe, AASHTO M180 in the United States, and AS\/NZS standards in Australia and New Zealand. EN 1317: European Standard for Road Restraint Systems EN 1317 is the European standard series covering road restraint systems. It provides a framework for evaluating and classifying roadside safety barriers, vehicle parapets, terminals, transitions, and other restraint systems. Unlike a material specification that focuses primarily on steel composition or dimensions, EN 1317 places significant emphasis on the performance of the complete ..."}
