Abstract

The design and verification of the new types of road safety barriers suffers from several deficiencies including a lack of prescriptive models for impact forces caused by various types of road vehicles. For specification of the load-bearing members of barriers, alternative procedures including dynamic, non-linear and probabilistic analyses may be applied. Detailed analysis is based on crash test simulations using models of vehicles based on the finite element method.
