Content
A ‘Green, Global and Connected’ City
The ‘Five Big Moves’ to manage the City’s growth and to guide future strategic policies and infrastructure:
A revitalised city centre at the heart of global Sydney
An integrated Inner Sydney transport network
A Liveable Green Network (LGN)
Activity hubs as a focus for the City’s village communities and transport
Transformative development and sustainable renewal
Sustainable Sydney
The Liveable Green Network
What it achieves?.....connections to a more liveable city
City Centre Village to village Parks and leisure
The Liveable Green Network
The Liveable Green Network is made up of LGN Priority Network Citywide Pedestrian Priority
Network City Wide Pedestrian Cycle
Priority and Primary Local Pedestrian Network
Primary Local Pedestrian Network
Prepare a Pedestrian Access and Mobility Plan (PAMP) for the LGN Focus on infrastructure audits
and recommendations Audit the four levels of network
priority for: Facility locations and quality Amenity, access and
compliance issues Missing facilities Intersection and crossing
treatments Path condition and widths
The auditing task
The City of Sydney wanted to audit the Liveable Green Network to identify gaps, issues and areas for improvement of the walking experience.
Proposal-stage decisions Calculate kilometres of network Use hand held devices with GIS
software Project commencement
decisions Agree on audit criteria upfront Recommend improvements on
site Trial and revise GIS data
collection tool Real-time upload of data
The approach to auditing
Three types of data collection1. Identification and recording of
pedestrian infrastructure.2. Assessment of pedestrian
infrastructure.3. Footpath width
measurements against existing GIS footpath segment layer.
The audit criteria
The location of every non-footpath pedestrian facility was recorded by the site auditors, whether it had any associated issues or not.
Provided Council with an up to date inventory of all pedestrian infrastructure.
1. Identification and recording of pedestrian infrastructure
Every issue associated with pedestrian facilities was recorded by the site auditors. Crossings: dimensions, alignment, condition,
clear zones, signage, missing Path condition: Cracked, uneven (severity:
slight, moderate or severe) Path obstructions: Street furniture,
vegetation, bins, other (degree of impact on the Pedestrian Through Zone)
Sight lines: Conflict at driveways Shared paths: signage, line-marking, pinch
points Shared zones: signage, presence of kerbs,
pavement markings Bus stops: clear space, tactile ground surface
indicators Accessible parking: lack of kerb ramps,
adjacent path width
2. Assessment of pedestrian infrastructure
Footpaths and shared paths Update Council’s footpath segment GIS
layer with the measured width Different widths for paths on the priority
networks Specific measurements were noted as:
below minimum, compliant and preferred Also noted where paths were missing on
the networks
3. Path width measurements
Collecting the data – GIS tool
Collector for ArcGIS IPad application
PAMP data was recorded for the LGN two ways: Placing a point or line to indicate
the presence of a pedestrian facility, record the issue if there were any and to recommend an improvement and;
Updating the footpath segments in the City of Sydney footpath layer to include a value for the measured width of each footpath segment.

Collecting the data
The site audits were undertaken between December 2014 – February 2015.
A team of up to five people a day audited the LGN, focusing on one area of the City at a time.
Each team member had a measuring tape and used the tablet’s in built camera.
Each auditor required two tablets each day due to battery drainage.
Collecting the data
Eight weeks of audits
Works were prioritised based on their location within high, medium or low priority areas throughout the CBD
New works were prioritised higher than upgrade works

The complete data collection was presented in a geodatabase for the City of Sydney. The geodatabase includes: Unique point or line ID. Location of pedestrian facilities. Type and severity of pedestrian facility issues (if any). Photo. Recommended improvement (if required). Cost estimate. Priority. Updated widths for the City of Sydney footpath segment layer
