- 3. Canberra as aHealthy and Active City • High cycling participation • 22% ride during a typical week • 40% work less than 10km from home • Canberrans walk an average of 26min per day Transport for Canberra: Transport for a Sustainable City 2012-2031 3

- 7. Australian Shared Zone SharedSpace • No legal definition • Interaction of all users with minimal guidance Australian Road Rules (ARR): • Definition - ‘installation of Shared Zone signage’ • Does not specify speed limit • Pedestrians have legal priority • Adopted in the ACT Road Rules 7
- 8. Other State Guides SpeedZones • Typically 10km/h • 20km/h examples implemented in ACT and QLD Traffic Volumes • Significant variation Design • Typically remove kerbs (single surface level) • Kerbs can be maintained in Brownfield sites or existing streets (NSW) State Max Vehicles per Hour Max Vehicles per Day NSW 100 1,000 VIC 200 1,000 WA - 300 8
- 9. Austroads Guidance Shared Zones: •Reduce vehicle speeds • Reduce traffic volumes • Increase pedestrian and cyclist safety • Improve amenity with no impact to access 9 Consistent with the Bunda Street Vision
- 10. Australian Shared Zone AngelPlace, Sydney, NSW Childers Street, City West, ACT Hunter Street Mall, Newcastle, NSW Hargreaves Street and Bull Street, Bendigo, VIC ‘One Size Fits All’ is not necessarily appropriate for Shared Zones 10
- 11. • 85% vehiclespeed is 30-40km/h • Approximately 500vph – expected to reduce • Pedestrian volumes are 3X vehicle volumes • Lane width = 3.5-4.0m – reduced in design • Undesirable through route • Pedestrian pinch points Bunda Street Context Bunda Street meets most (known) criteria for Shared Zone 11
- 12. Key Design Considerationsand Challenges • Speed limit – safe, practical • Retro-fitting the Woonerf Principle • Parking and loading – requirement of small business • Funding limitations – staged approach • Intersection/ entry treatments – clear visual cues 12 Akuna Street Mort Street
- 13. • Welcoming forpedestrians & cyclists of all levels • 10km/h – not well received by stakeholders • 20 km/h – potentially reduced to 10km/h in the future • Self enforcing speed limit for compliance • Reduced fatality rate Speed Limit 13
- 14. • Horizontal andvertical deflection • Removal of line marking • Strategic tree planting • Urban design features • Reduced lane widths • Paved materials • Kerb build outs Retro-Fitting the Woonerf Principle Constrained Reasonably ambiguous Limited delineation 14 Competing Priorities
- 15. • Reduced parkingspaces • Parallel parking – safer than angled for Bunda Street • Relocation to improve sight lines • Alternate Sides • Short-term – increase efficiency • Consolidated loading Parking 15
- 16. Intersection Treatments Bike Box Raised Threshold Reduced Width Planting Restricts Peds 16 Interaction BetweenShared Zone and Traffic Signals
- 17. Stage One • Intersectionsand desire lines • Consider high priority areas • Raised pavement areas • Horizontal deflection • Maintain major traffic control devices Stage Two (Future) • Raised pavement along the length of Bunda Street • Scramble crossing • Remove further traffic control devices Staged Approach 17
- 18. Additional measures: • Usereducation • Safety campaign • Heavy vehicle access restrictions Future Comparative Measures: • Level of traffic control devices • Number of pedestrians, vehicles and cyclists • Number and type of crashes • Number of key pedestrian crossing locations • User opinion and retail satisfaction Implementation and Evaluation 18
