To estimate the steel guardrail’s protective function in real-time experimental approaches, freight vehicles clash with steel guardrails on expressways, resulting in the steel guardrail collapsing and the freight car rushing off the road. The dynamic simulation results were predicted using the LS-Dyna FE simulator at a speed of 90 km/h and impact angles of 10°, 15°, 20°, 25°, and 30°. A two-wave beam steel guardrail has been compared to the simulation results. In this study, finite element (FE) simulation is carried out on the collision between freight cars and an expressway three-wave steel guardrail. As a result, the steel guardrail’s guiding ability, anti-collision performance and safety behaviour are crucial indices to measure expressway steel safety in collision accidents between freight vehicles and the steel guardrails. Because it may prevent the freight vehicle from speeding off the road, a steel guardrail can help keep the driver safe. Unexpected events, such as accidents, might cause a freight vehicle travelling on the road to lose control. The experience gained from over 50 years of testing and research programs at Exponent gives us unique technical knowledge and insight to provide rigorous scientific analyses to evaluate vehicle dynamics, impacts, and occupant kinematics.Steel guardrails on expressways are a vital piece of traffic safety infrastructure. These methodologies include computer simulation, animation, and full-scale crash testing.
