Objectives of 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 truckmounted attenuators), terminals and transitions, motorcycle
protection devices.

Timetable of SAVeRS
Total Budget of 525 k€ (approx. 700 k US$)
TRB-ERF, 11 April2013
The expected outcome
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.
TRB-ERF, 11 April2013
The expected outcome
The selection criteria in the Guide will be
based also on life cycle principles
The applicability of the Guide will be
tested in a Pilot Project by Balfour
Beatty Major Civil Engineering
The Guide will be implemented in a
user-friendly web-based tool

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
