A Simulation-Based Concept for Assessing The Effectiveness of Forgiving Roadside Treatments
This article introduces a new way to analyze roadside treatments, notably those that are considered “forgiving” which are defined as those roadsides that aim to ensure that vehicles leaving the travel lane regain control or at least reduce the likelihood of collisions with roadside obstacles. The authors note that run-off-road accidents are responsible for nearly half of all road accident fatalities in the European Union. The authors conducted simulations of various run-off-road accident scenarios at rea-world, high-risk sites, including the analysis of vehicle dynamics. Their concept is based on an accurate replication of a three-dimensional road model. In simulation, various roadside designs are implemented to obtain information about their effect on safety. Indicators used to rate effectiveness of the roadside treatment are head injury criterion (HIC) and the abbreviated injury scale (AIS), both of which describe the injuries to occupants. The authors’ simulations demonstrate that the risk of fatal injuries strongly declines with highway designs that include forgiving roadsides. They propose that, in the future, the concept could be utilized for road safety inspections and road safety audits.
