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

It is suggested that candidates attend An Introduction to Road Restraint Systems & Assessment of Need (RRS) before attending this course.

Aims & Objectives:

  • 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

Course Outline:

  • 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Interpretation of withdrawn documentation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

Benefits of Attending:

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

Intended For:

  • 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

Pre-Course Requirements:

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
