The Dutch road administration often prefers a flexible design for guardrail construction. The design seems to give more protection in the case of an accident than does a stiff guardrail. A study of the differences between the types of rails indicated that the stiff steel design is most likely to decelerate the colliding vehicle and to throw the colliding vehicle back into the traffic lane at the greatest angle. The extra deceleration is unlikely to lead to a more severe injury for occupants, but will increase the chance of a second collision. Application of the VEDAYC computer model to simulate various collisions and construction designs provided a reasonable means of comparing responses to collisions. Nevertheless, it was found that the model needs improvement.
