| Abstract: | An impact between vehicles and roadside sign posts is an extremely dangerous event. In the paper, the damage accidents of vehicles impacting sign posts on highways are investigated, and there roadside sign posts tested by finite element simulation. According to the results got previously, the improvements for roadside sign post design in structure are right, so as to reduce injury severity to vehicles and occupants in impact accidents. |
