About the project
Run-Off-Road (ROR) crashes are extremely severe road accidents that often result in severe injuries or fatalities. The accident analysis conducted within the RISER Project, funded by the EU, concluded in 2005, highlighted that even though only 10% of the total accidents are single vehicle accidents (SVA, typically associated to the run-off-road type accidents) the rate of SVA events increases to 45% when only fatal accidents are considered. To reduce the severity of ROR crashes, “forgiving roadsides” need to be designed and this includes identifying where there is a need for a Vehicle Restraint System (VRS) and what appropriate VRS should be selected for specific location and traffic condition.
At present time, whilst there are standards covering the testing, evaluation and classification of VRS within Europe (EN1317, EN12767 etc), their selection, location and installation are based upon national guidelines, often produced by National Road Authorities (NRA) and/or overseeing organisations. Due to local conditions, these national guidelines vary across Europe.
Objective and expected results
The aim of the project is to produce a practical and easily understandable VRS guidance document and a web-based user-friendly tool that will allow the selection of the most appropriate solution for all types of VRS: safety barriers including parapets; crash cushions, including Truck-Mounted Attenuators, terminals and transitions; motorcycle protection devices. The guidance document and the web-based tool will have with the following aims:
- ensuring the safety of road users, road workers and third parties;
- optimising performance in use;
- maximising serviceable life;
- minimising whole life costs.
To ensure that the SAVeRS project output will be a useable, robust and realistic guidance tool to aid designers in their choice and selection of VRS, a specific evaluation Task will be performed to test the effectiveness of the guidelines and of the tool developed in the project. The guideline and tool will be tested for application to new and current designs and against sites where VRS have been in use for some years and performance information is available.
