  1. Safey Audits.Explanation of Audits and the Requirements at each Stage of the Audit Process. Presented by Harry Cullen Senior Project Manager, Road Safety & Research, NRA Prepared by Stephen Lambert & Lucy Curtis, Regional Road Safety Engineers, National Roads Authority, Ireland CEDR SG Road Safety Meeting April 6th 2005

  2. Introduction • What is a Safety Audit • Requirements & Guidelines • At what stages are they done • What to look for • Who should do them • Cost CEDR SG Road Safety Meeting April 6th 2005

  3. What is a Road Safety Audit? • Process for checking the safety of new schemes on roads • Systematic • Based on safety principles – experience / research • Ensures that new schemes will not become the accident sites of the future. • Looks at schemes from ALL road users’ point of view CEDR SG Road Safety Meeting April 6th 2005

  4. About Safety Audits • Road Safety Audits • Identifies potential safety hazards within a scheme and formulates recommendations for dealing with the identified hazards. • Applies the experience gained from accident remedial work to prevent future accidents. • Not there to stop developments, there to make developments safer. • Not a check of compliance with design standards. CEDR SG Road Safety Meeting April 6th 2005

  5. Road Safety Audit is not • An opportunity to redesign the scheme • A technical check • A design standards check CEDR SG Road Safety Meeting April 6th 2005

  6. Requirements & Guidelines • The Design Manual for Roads & Bridges (DMRB) produced by the National Roads Authority, contains the following standards for Road Safety Audits: • 2001- NRA DMRB HD 19/01 • NRA DMRB HA 42/01 CEDR SG Road Safety Meeting April 6th 2005

  7. DMRB Design Manual for Roads & Bridges • It is the Irish Standard for National Roads • It has specific Requirements as to when and how Safety Audits should be carried out. CEDR SG Road Safety Meeting April 6th 2005

  8. WHEN! • Road Scheme :- all work that involves a permanent change to the existing road layout. • The standard defines the relevant road schemes which are to have a Safety Audit:- • All National Road schemes currently being prepared. • All work carried out under agreement with the NRA resulting from developments alongside or affecting National Roads. • (Sec 2.1 NRA HD/01) • Major Temporary Traffic Management Schemes (at discretion of Design Office PM) CEDR SG Road Safety Meeting April 6th 2005

  9. When to do Road Safety Audit • For large schemes • Stage F - Feasibility - Route Selection • Stage 1 - Preliminary design - Land Acquisition • Stage 2 - Detailed design - Tender • Stage 3 - Prior to opening to traffic • Monitoring after 1 and 3 years CEDR SG Road Safety Meeting April 6th 2005

  10. When to do Road Safety Audit • For smaller schemes • Stage 1/2 – Completion of design • Stage 3 – Prior to opening to traffic • Monitoring after 1 and 3 years CEDR SG Road Safety Meeting April 6th 2005

  11. When to do Road Safety Audit • For developments • Stage F - If major development • Stage 1 – Preliminary design • Stage 2 – Detailed design • Stage 3 – Prior to opening to traffic • Monitoring after 1 and 3 years CEDR SG Road Safety Meeting April 6th 2005

  12. The safety audit task • Examination of scheme detail • Check lists • Control data • Role play as different users • Report • Monitoring CEDR SG Road Safety Meeting April 6th 2005

  13. What to look for • At all stages: • Mistakes • Opportunities to include accident-reducing elements • How all road users will cope at all times • Interaction between design elements • Departure from standards CEDR SG Road Safety Meeting April 6th 2005

  14. What to look for • At Stage 1 • Road Alignment • Junction Layout • Accesses • Possible detailed design problems • At Stage 2 • Design changes since stage 1 • Design details • At Stage 3 • Design changes since stage 2 • Has the scheme been built as designed ? CEDR SG Road Safety Meeting April 6th 2005

  15. Who should do Audits • Must be independent of the design team • At least two people, three on large schemes • Safety engineering “experts” • Approved by NRA, if on national road • Road Safety Officers, Specialists, Police (stage 3 only) CEDR SG Road Safety Meeting April 6th 2005

  16. To Get NRA Approval Team Member • 2 yrs experience as roads or traffic engineer • 3-5 day approved course in Road Safety Audit • 5 “practice” audits as a trainee Team Leader • Either 2 years experience in Accident Investigation and Prevention or 2-week approved course in Road Safety Engineering • 10 “practice” audits as trainee. CEDR SG Road Safety Meeting April 6th 2005

  17. In Design-and-Build or PPP (once PPP process has started) the RSA team must be from a completely separate organisation from the design team. NOT from the same firm or any part of the consortium at all. • For D&B and PPP contracts the road safety auditor is more likely to be continually checking the scheme as the design progresses. There may be a number of pre stage 2 and stage 3 road safety audits. CEDR SG Road Safety Meeting April 6th 2005

  18. Skills required • Road safety engineering experience • Knowledge of design standards • Knowledge of current road safety research • Diplomacy • Teaching / Learning CEDR SG Road Safety Meeting April 6th 2005

  19. Cost • Costs small in relation to over all scheme costs. • 1500 to 6000 Euro per stage • 3500 to 20,000 Euro for a full scheme • DMRB estimates a FYRR of 600% for SA’s • Findings show schemes audited on average have one casuality per year less than non audited schemes.
