  2. Cross-border funded Transnational Research Programme funded by Belgium/Flanders, Germany, Ireland, Norway, Sweden, United Kingdom

  4. Objectivesof SAVeRS The objective of the SAVeRS project is to produce a practical and readily understandable Vehicle Restraint System (VRS) guidance document and a user-friendly web-based tool that will allow the selection of the most appropriate solution in different road and traffic configurations for all types of VRS: safety barriers including parapets, crash cushions (including truck-mounted attenuators), terminals and transitions, motorcycle protection devices.

  5. Workplanof SAVeRS WP1 – DefinitionofParameters Gavin Williams (TRL) WP2 – InfluenceofParameters Robert Thomson (VTI) TK 1.1 Analysisof NRA methodologies (TRL) [withTCD, UNIFI, VTI, AIT, ZAG, BRRC] TK 1.2 LiteratureReview (TCD) [withTRL, UNIFI, VTI, AIT, ZAG, BRRC] TK 2.1 Analysisofseverityofincidents (AIT) [with UNIFI, TRL, VTI, TCD, ZAG] TK 2.2 Whole life costanalysis (VTI) [with UNIFI, TRL, AIT, TCD, ZAG] WP0 – Project Management Francesca La Torre (UNIFI) WP4 – Dissemination and Workshops BinePengal (ZAG) [withall] WP3 – Creationof the GuidanceDocument Francesca La Torre (UNIFI) TK 3.1 – Preparationof the Guideline (UNIFI) [with TRL, VTI, ZAG, AIT, BB] TK 3.2 – Validationof the VRS placementguidance (UNIFI) [with TRL, AIT, BB] TK 3.3 – Pilotapplicationto a project (BB)

  6. Timetableof SAVeRS December 31, 2014 January 1, 2013 Total Budget of 525 k€ (approx. 700 k US$)

  7. The expectedoutcome The Guideline will be structured in 5 sections: • Identification of the need for a VRS (barrier placement guidance):allow the user to identify if there is a need for a VRS and the LON; • Safety barriers (including parapets): provide guidance for selecting the most appropriate VRS, which is tested according to EN1317-2 will be provided in different road section configurations. • Crash cushions (including TMAs), terminals and transitions: this section of the guide allow to select the attenuators according to EN1317-3 and the Truck Mounted Attenuators (TMAs) for which a European Technical Specification is still under development and that are currently tested according to the US NCHRP350 or the UK Highways Agency’s TD49/07. • Motorcycle restraint systems (MRS): this section of the guideline will provide a tool to identify where an MRS tested according to EN Technical Specification CEN/TS 1317-8 (“Road restraint systems Motorcycle road restraint systems which reduce the impact severity of motorcyclist collisions with safety barriers”) is required and the criteria to select the most appropriate MRS; • Recommendation for the implementation of the guideline by National Road Administrations.

  8. The expectedoutcome The selectioncriteria in the Guide willbebasedalso on life cycleprinciples The applicabilityof the Guide willbetested in a Pilot Project byBalfour Beatty Major Civil Engineering The Guide willbeimplemented in a user-friendlyweb-basedtool

  9. National standards ….. • Collect: • National standards • National guidelines • Available database from Road Authorities, police, research institutes, etc… • Categorize: • Which parameters are used for assessing the need and the type of VRS • Which approach are used for assessing the need and the type of VRS • Produce: • Data Matrix: which essential parameters will be analyzed in WP2 • Report part 1.1

  10. Data matrix Example of data matrix (not the actual matrix) One for the need identification and one for the VRS performance selection (for each VRS)
