4 Objective of this Standard is to ensure thatthe road safety implications of all HighwayImprovement Schemes are fully considered for all usersof the highway including those working on the Overseeing Organisations attach greatimportance to the improvement of road safety. The useof Standards that are based on road safetyconsiderations helps to ensure that this objective is elements of a Highway ImprovementScheme design are based on the use of DesignStandards and Advice Notes. Whilst these Standardsand Advice Notes provide a basis for safe design, carehas to be taken when combining them to avoid thecreation of hazards.

5 However, it is important to notethat road Safety Audit is not exclusively concernedwith those aspects that are associated with theinteraction of Design Standards. The objective of RoadSafety Audit is to identify any aspects of a HighwayImprovement Scheme that give rise to road safetyconcerns and, where possible, to suggest modificationsthat would improve the road safety of the road safety has always been consideredduring scheme preparation, there have been instanceswhere details of the design have contributed toaccidents on newly opened schemes. Design Teams donot necessarily contain staff with Accident Investigationor road Safety Engineering experience andconsequently they may not adequately understand thenature of accident Safety Audits are intended to ensure thatoperational road safety experience is applied during thedesign and construction process in order that thenumber and severity of accidents is kept to a identify and address problem areas using theexperience gained from accident reduction schemes,accident investigation and research work.

6 TheOverseeing Organisations aim is that the monitoring ofaudited schemes will result in better informed designs,leading to schemes that rarely require road safetyrelated changes after is recommended that Design Teams includestaff with road Safety Engineering experience toensure that safety issues are considered during , road safety engineers included within theDesign Team will not be permitted to be part of theRoad Safety Audit Teams due to their lack ofindependence from the scheme design as their viewsmay be influenced by familiarity and a natural pride ofauthorship.

7 The involvement of a road SafetyEngineer within the Design Team should not beconsidered to be a satisfactory or acceptable substitutefor undertaking a road Safety of this Standard sets out the procedures required toimplement road Safety Audits on HighwayImprovement Schemes on trunk roads includingmotorways. It defines the relevant schemes and stagesin the design and construction process at which auditsshall be undertaken and sets out the requirements forpost-implementation accident Standard is commended to other document includes several significantchanges from the previous Standard HD 19/94 ( ) and Advice Note HA 42/94 (DMRB )namely: the introduction of Interim road Safety Audit; additional guidance on the suitable training, skillsand experience recommended for Audit Teams; guidance on the relationship between RoadSafety Audit and Health and Safety Legislation.

8 The requirement for the accident monitoring ofcompleted Highway Improvement Schemes in theform of a Stage 4 Mandatory sections of this document arecontained in boxes. The Design Organisation mustcomply with these sections or obtain agreement toa Departure from Standard from the OverseeingOrganisation. The remainder of the documentcontains advice and explanation, which iscommended to users for 5 SECTION 2 part 2 HD 19/03 November 20031/2 Chapter 1 IntroductionApplication in Northern This Standard will apply to those roadsdesignated by the Overseeing This Standard supersedes HD 19/94 ( ) and HA 42/94 (DMRB )

9 , which are This Standard shall be used forthwith for allRoad Safety Audits on all Highway ImprovementSchemes with the exception of audits for which abrief in accordance with HD 19/94 and HA 42/94has been issued before the publication date of HD19/03. Those audits may be completed inaccordance with HD 19/94 and HA 42 Exemptions granted (under paragraph ofHD 19/94) for Highway Improvement Schemesthat are incomplete at the publication date of HD19/03 are not valid from that date and all suchschemes shall be audited at the end of the currentdesign or construction stage, and at Stage Safety Audit.

10 The evaluation of HighwayImprovement Schemes during design and at the end ofconstruction (preferably before the scheme is open totraffic) to identify potential road safety problems thatmay affect any users of the highway and to suggestmeasures to eliminate or mitigate those problems. Theaudit process includes the accident monitoring ofHighway Improvement Schemes to identify any roadsafety problems that may occur after opening. ThisStage 4 Audit will include the analysis and reporting of12 and 36 months of completed personal injury accidentdata from when the scheme became road Safety Audit: The application ofRoad Safety Audit to the whole or part of a HighwayImprovement Scheme at any time during thepreliminary and detailed design stages.
