Innovative Research Into Road Restraint Systems

Key to understanding the needs and building road infrastructure management tools to prevent and mitigate run-off-road accidents is to identify hazards and their sources which are a result of wrong design, construction, installation and maintenance of road restraint systems [1]. Building such tools requires advanced studies with field tests, simulations and models to demonstrate the effects of selected parameters on road user safety [2]. Delivered under the Road Innovation programme, two research projects (ROSE and LifeROSE) are designed to help with that. The main aim of the pro-jects is to develop a method to help with an optimal choice of road restraint systems depending on the type and level of hazard, road class, size and structure of vehicle streams and driving condi-tions (vehicle speed) on the road. To that end a number of field tests were carried out designed to identify hazards and build a database of road elements. The article presents a general characteris-tics of the study, fieldwork and simulation and analytical tests required to meet the objectives. It also gives a detailed description of the crash tests conducted in the field for the two projects. A series of crash tests involving vehicles and barriers was carried out to assess how the selected restraint systems behaved and, as a result, to identify how selected barrier design factors and dy-namic vehicle factors affect the functional features of safety barriers under investigation.
