1 Framework Traffic Management for Shared Zones in Large Private Estates AITPM 2014 National Conference Presented by : Wayne Johnson Senior Project Manager GTA Consultants Wayne.johnson@gta.com.au

2 Outline of Presentation Project Brief Application Shared Zones Origin and Principles Australian and New Zealand Legislation Framework Traffic Management Plan Site Observations and Recommendations Conclusions 2

New Zealand Legislation Framework Traffic Management

3 Project Brief Internal audit of retirement villages revealed safety concerns and inconsistent shared zone treatments Review the operation and management of the existing road network within a selection of retirement villages throughout Australia Segregation/ traffic management/ signage? Review State and Territory Legislation Prepare a Framework Traffic Management Plan Village Manager to prepare Traffic and Pedestrian Guideline for each Retirement Village 3

villages throughout Australia Segregation/ traffic management/ signage?

4 Application Large Private Estates include: Retirement Villages Industrial Estates Sporting Venues Tourism Precincts Internal Road Networks Estate Shared Zone Users: Pedestrians and Cyclists Mobility Scooters Cars Delivery and Maintenance Vehicles

Internal Road Networks Estate Shared Zone Users: Pedestrians

5 Shared Zone Origin and Principles Origin: Woonerf Living Yard Shared Zone Principles Safe for all road users, particularly pedestrians Reduce the risk of crashes between vehicles and pedestrians Require lower vehicle speeds Enhance the quality of the street environment

pedestrians Reduce the risk of crashes between vehicles and

6 Australian and New Zealand Legislation - Variations 6

7 Framework Traffic Management Plan Purpose: to provide a framework of guidance for the planning, design and management of the traffic and transport environment within private residential, industrial and tourism/recreational precincts.

management of the traffic and transport environment within

8 Site Observations and Recommendation Road Hierarchy - Site Observation Public Road access to and from the external road network Collector Road a central spine or loop road Access Way link to residences

and from the external road network Collector Road

9 Site Observations and Recommendation Road Hierarchy - Recommendation The traffic management plan shall define the road type and each road must be treated differently based on the road hierarchy.

10 Site Observations and Recommendations Non Shared Zones - For locations where traffic > 50 vph: Vehicle priority Traffic calming devices Separated pedestrian routes

11 Site Observations and Recommendation Shared Zone Road Design - Site Observation Established road network (Brownfield) A variety of access arrangements Length of Shared Zone Shared Zone Road Design Recommendation Design such that the speed limit is self enforced Minimum width of 2.8m one-way and 5.6m two-way Single access location No kerb and gutter - No separation of pedestrian paths Different pavement surfacing and texture Good sight lines, particularly at intersections 11

limit is self enforced Minimum width of 2.8m one-way and 5.

12 Good Shared Zone Examples 12

13 Site Observations and Recommendation Entry and Exit Points Site Observation No transition zone Entry and Exit Points Recommendation Change in road surface/ pavement colour: 2-3m Visual cues

Entry and Exit Points Recommendation Change in

14 Site Observations and Recommendation Traffic Calming - Site Observation and Recommendation Pavement colour and texture Speed bumps No linemarkings or kerbs 14

15 Site Observations and Recommendation Pedestrian Facilities - Site Observation Variety of treatments Pedestrian crossings Some crossings direct pedestrians into oncoming traffic flow Pedestrian safe zone Pedestrian Facilities Recommendation Pedestrians have priority within a Shared Zone

direct pedestrians into oncoming traffic flow Pedestrian safe zone

16 Site Observations and Recommendation Signage and linemarking Observation Inconsistent/ non-standard treatment Give Way/ Stop Signage and linemarking Recommendation Remove signs and linemarkings (except parking bays) Intersection treatment Start and end of Shared Zone Vahl The best way to make a street safe is to make it unsafe

Recommendation Remove signs and linemarkings (except parking bays) Intersection

17 Site Observations and Recommendation Speed limit Site Observation Inconsistent speed limits 15 km/hr advisory speed Speed limit Recommendation 10 km/hr walking pace

18 Site Observations and Recommendation Service and Delivery Vehicles Site Observation Insufficient turn-around areas Trucks reversing Service and Delivery Recommendation Pedestrian route Traffic and Pedestrian Management Plan

turn-around areas Trucks reversing Service and Delivery

19 Conclusions Design the shared zone such that the speed limit is self enforcing Raised gateway treatment Provide distinctive pavement colour/ texture to provide visual cues to motorists No separation between pedestrians and vehicles Follow National/State Legislation In general, minimise road markings, signage, intersection controls less is more.

to motorists No separation between pedestrians and vehicles Follow National/State
