Road Safety Audit Brief

The Road Safety Audit Brief defines the scope of the Road Safety Audit to be undertaken. The Project Sponsor has overall responsibility for the Road Safety Audit Brief. However, the Design Team may prepare the Road Safety Audit Brief on their behalf. A copy of the Road Safety Audit Brief must be forwarded to the Project Sponsor for formal approval in advance of the Road Safety Audit. The Project Sponsor may instruct the Design Team to delete unnecessary items or to include additional material, as they consider appropriate. The Project Sponsor must document the reasons for deleting or adding any information to the Road Safety Audit Brief. The Project Sponsor must issue the Road Safety Audit Brief and instruct the Road Safety Audit Team when the scheme is ready to be Road Safety Audited.

To maximise the benefit from the Road Safety Audit, the brief needs careful preparation and must include sufficient information to enable an efficient Audit to be undertaken. An Audit Brief should contain the following:

  • a) A description of the proposed Highway Improvement Scheme clearly identifying its objectives.

  • b) Scheme drawings showing the full geographical extent of the scheme and including the areas beyond the tie-in points.

  • c) Details of determined and pending Departures and Relaxations from Standards, and/or the Design Strategy Record(s) where they have been produced for an improvement to an existing motorway or trunk road.

  • d) Clear identification of the elements of the scheme proposals included within the scope of the Road Safety Audit to be undertaken and also those elements of the scheme that fall outside of the scope, including strategic decisions. The Road Safety Audit Brief should clearly identify where the scope of the Road Safety Audit has been extended to allow consideration of strategic decisions.

  • e) General scheme details, to help give an understanding of the purpose of the scheme and how the layout will operate, including design speeds, speed limits, traffic flows, forecast flows, queue lengths, NMU flows and desire lines (including NMU Context and Audit reports undertaken in accordance with HD 42/05 (DMRB 5.2.5)). Also details of any environmental constraints on the design and how these may have affected any strategic decisions made.

  • f) Details of any safety risk assessments undertaken as part of the design process (on the Strategic Road Network in England these will be undertaken with reference to GD 04/12 “Standard for Safety Risk Assessment on the Strategic Road Network” (DMRB 0.2.3)).

  • g) Any other relevant factors which may affect road safety such as adjacent developments (existing or proposed), proximity of schools or retirement/care homes and access for emergency vehicles.

  • h) The Road Safety Audit Brief should identify if the location of the Highway Improvement Scheme should be visited at a particular time of the day (e.g. peak traffic periods or beginning or end of the school day).

  • i) For on-line schemes and at tie-ins, the previous 36 months personal injury collision data in the form of ‘stick plots’ and interpreted listings. The personal injury collision data should cover both the extent of the scheme and the adjoining sections of highway.

  • j) At Road Safety Audit Stages 2 and 3, details of any changes introduced since the previous Road Safety Audit stage.

  • k) Any changes in the Highway Improvement Scheme that are not shown on the design or As-Built drawings.

  • l) Plans using an appropriate scale for the Road Safety Audit Team to mark up for inclusion in the Road Safety Audit Report.

  • m) Previous Road Safety Audit Reports, Interim Road Safety Audit Reports, Road Safety Audit Response Reports and Exception Report(s)

  • n) Contact details of the Maintaining Agent to whom any identified maintenance defects should be notified (by telephone and immediately confirmed in writing for serious defects) separately from the Road Safety Audit Report.

  • o) Details of the appropriate Police contact.

  • p) Details of any site access arrangements including any specific health & safety requirements such as inductions, Personal Protective Equipment and vehicle livery requirements.

If the Road Safety Audit Team considers the brief to be insufficient for their purpose then requests for further information should be made to the Design Team Leader and copied to the Project Sponsor. Any information requested but not supplied to the Audit Team should be identified in the introduction to the Audit Report.
