An Introduction to the Provision of Road Restraint Systems on Local Authority Roads (PRRSLA)

• To gain an appreciation of the need to assess highways for the use of Road Restraint Systems (RRS)
• To provide the candidate with an understanding of the processes and limitations of PRRSLA
• To understand the decision making processes required when selecting the assessment pathway within PRRSLA
• To apply the assessment output(s) in the highway environment
• To have knowledge of the available data sources that may influence the decision making processes

• PRRSLA Limitations and Exclusions

Understanding usage and application
PRRSLA as a tool, including the selection process
RRS types excluded from assessment
Interpretation of withdrawn documentation

• Headline Data usage
• The PRRSLA Methodology:

Method A – Incident Driven Assessment
Method B – TAL 6/03
Method C – Risk Based Assessment

• Output considerations & Appendix 4/1
• Use of data for justification (Cost Benefit)
• Other considerations

Increased understanding of the PRRSLA process and its use within a risk based decision making assessment of need for road restraint systems.

• Those undertaking risk-based assessments of need (RRS)
• Those managing highway engineers undertaking risk-based assessments of need (RRS)
• Inspectors (RRS and Structures) and Road Safety Engineers who wish to understand how the PRRSLA toolkit assists with the decision making process and the implications of RRS installation

Candidates are to indicate prior to the training if they:

a: have used PRRSLA and if so, which models
b: have access to PRRSLA, or
c: have no understanding of PRRSLA
