Safer Roads By David Moir

  1. 1. August 2008 Safer Roads Seminar David Moir, Executive Manager, Member Advocacy RACWA
  2. 2. What is AusRAP? Sister program to ANCAP Part of iRAP
  3. 3. What is AusRAP? EuroRAP usRAP Costa Rica Malaysia & Vietnam South Africa AusRAP Chile KiwiRAP
  4. 4. Concept of a Dangerous Road What makes a road dangerous? - Responses to open-ended question - 2004 Poor surface. Uneven. Poor maintenance. 38% 42% Potholes. Large potholes. Not fixed. 32% 36% Inadequate signage 21% 14% As in 2004, the main Narrow roads 17% 21% concept of a dangerous road relates to its Poor visibility 16% condition and 12% maintenance. Inadequate lighting 13% 11% Corners, bends 11% 13% Weather 11% - ANOP, 2007
  5. 5. Here’s how the National Strategy says we could save 700 lives every year Improved Safer Driver New roads vehicles behaviour technology
  6. 6. A safe system: Safer drivers in safer cars on safer roads
  7. 7. How safe are our roads? Rate has increased
  8. 8. WA’s contribution is nothing to be proud of 12.0 11.5 Western Australia 11.0 10.5 Deaths per 100,000 population 10.0 9.5 9.0 8.5 8.0 Australia 7.5 7.0 6.5 6.0 National target 5.5 5.0 Dec-00 Dec-01 Dec-02 Dec-03 Dec-04 Dec-05 Dec-06 Dec-07 Dec-08 Dec-09 Dec-10
  9. 9. Where AusRAP fits in Communication AusRAP and funding ARRB NetRisk Road network Uses safety triggers to identify screening high risk parts of a road network for investigation ARRB RSRM Site treatment Assess, prioritise and track particular site treatments
  10. 10. Who will benefit? Road users: Community pressure Awareness of risk Adapt road user behaviour Governments, authorities, planners and engineers: Business case for road improvements Tracking of road improvements Decision-making about road investments Compare performance of roads Discussion on technical standards
  11. 11. How does AusRAP star-rate roads? Star-ratings measure safety built-in to the road Identifies risky sections of road before a crash occurs In NZ in 2004, 54% of fatal crashes occurred where there had been no other injury crashes in the previous 4 years Measures likelihood and severity Method developed with ARRB Consulting
  12. 12. How is the data collected?
  13. 13. What elements are inspected? For run-off road and head-on crashes: divided or undivided lane width sealed shoulder width alignment terrain line marking roadsides traffic speeds overtaking provision
  14. 14. What elements are inspected? For intersection crashes: type of intersection volume of traffic on side road (or railway) traffic speeds alignment of side roads (or railway) sight distances right and left turn provision
  15. 15. Road Protection Score (RPS) Star-ratings are based on a RPS Crash risk ‘score’ can be assigned to each of the road’s design elements Eg: crash risk on road with narrow lanes (<2.8m) 50% higher than wide lanes (3.6m) RPS combines these scores to form a star-rating
  16. 16. Bruce Highway, QLD Severe roadside Narrow shoulders Bad overtaking Curves Undivided
  17. 17. Great Eastern Hwy, WA Straight Moderate roadside Moderate shoulders Good overtaking Good lines Undivided
  18. 18. Pacific Hwy, NSW Straight Severe roadside Good overtaking Good lines Wide shoulders Wide lanes Divided – innovative use of barriers
  19. 19. ‘Risk Worm’
  20. 20. AusRAP Star Ratings AusLink National Network ***** 0% **** 42% *** 55% ** 3% * 0%
  21. 21. AusRAP Star Ratings AusLink National Network in NSW ***** 0% **** 24% *** 68% ** 8% * 0% Before After
  22. 22. Crash costs by star rating (cents per kilometre travelled) 10 Crash costs halved Crash costs halved again 5 3 2 3 4 Star rating
  23. 23. Lifting the Network to 4 stars Research question: What is the least-cost way of lifting a significant proportion of the national network to 4 stars?
  24. 24. Preliminary Results for NSW Total investment: $14 billion (no time period set) ($ million)
  25. 25. Preliminary results for NSW Improvements in Star Ratings as a result of investment (% of network by star rating) 80% 68% 70% After Before 61% 60% 50% 39% 40% 30% 24% 20% 8% 10% 0% 0% 0% 0% 0% 0% 1 2 3 4 5 Star rating
