The document summarizes changes to speed limits in Western Australia over the past decade and examples of recent speed limit demonstration projects. Some key points: - Speed limits have generally been reduced, with area-wide 70km/h and 40km/h limits introduced in fringe urban and CBD areas respectively. - Demonstration projects in Fitzgerald Street, Beaufort Street, and Leederville reduced speeds and received little public backlash. Before and after studies are planned. - A speed limit reduction on Old Coast Road from 110km/h to 100km/h achieved lower 85th percentile speeds with police presence and variable message signs. - Key issues for the future include whether 110km/h is suitable for all

- 1. Speed Zoning Presentation Craig Wooldridge Manager Traffic Operations and Services November 2009
- 3. Most changes have been reductions.
- 4. Area wide 70km/h limits introduced in fringe urban areas.
- 5. Area wide 40km/hlimits introduced in limited CBD areas.
- 7. Fitzgerald StreetSpeed Reduction Demonstration
- 8. Fitzgerald StreetSpeed Reduction Demonstration (cont) Speed cushions installed in June 2008 over 400m in main pedestrian area in North Perth. 25,000 vehicles per day. 1400 pedestrian crossings per day. Before treatment 85th percentile speed 55km/h. After treatment 85th percentile speed 40km/h. Less than 50 complaints. 2 year before/after crash review committed. Revised regulatory speed limit to be decided at the end of the review.
- 9. Beaufort Street Variable Speed Limit Demonstration
- 10. Beaufort Street Variable Speed Limit Demonstration (cont) Installed in August 2009. Electronic speed signs. 40km/h limit from 9am to 10pm Sunday to Thursday. 40km/h limit from 9am to 1am Friday and Saturday. Times of operation by agreement with local working group. 60km/h limit at other times. Two year before/after study.
- 12. Leederville 30km/h Demonstration Installed in September 2009. Previously posted at 50km/h. 85% speed before change was 36.5km/h. Positive community and business feedback. Only 1complaint. 2 year before/after study to be completed.
- 13. Old Coast Road – Single Carriageway Section Speed limit reduced from 110 to 100km/h in February 2009. Strong planning and co-operation between Main Roads and Police. Before and after VMS presence. After Police presence. Before 85% speeds - 109 to 115km/h After 85% speeds - 101 to 107 km/h Speeds just after overtaking lanes around 120km/h. Only 1 public complaint. No before/after crash study due the impacts of Forrest Hwy.
- 14. Key Issues for the Future Is the 110km/h blanket limit suitable for gravel roads? Is the 110km/h limit suitable for lower quality country roads? Do we need to remove some speed limits eg. 20km/h increments instead of 10km/h? Political support for speed limit changes.
- 15. Moving Forward Further demonstration projects required with before and after studies to gain political/community support. The use of speed cameras will be required at high risk/high crash locations to achieve lower speeds.
