Walk21 Charter

Our vision is to maximise the value of location intelligence in decision making, planning and service delivery for the benefit of NSW Government, industry and communities.

Supportive land-use and spatial planningCommunities have the right to expect land-use and spatial planning policies which allow them to walk to the majority of everyday services and facilities, maximising the opportunities for walking, reducing car-dependency and contributing to community life.

NSW Spatial Strategy

Walking and Public Transport

In the TfNSW Integrated Public Transport Service Planning guidelines walking is a mode and is measured as criteria of access to services and facilities.

Increase the percentage of the population living within 30 minutes by public transport of a city or major centre in metropolitan Sydney– Walking is assumed

Walking catchment is generally within 800 metres (as the crow flies) of the stop/wharf for bus and ferry services.

The measurement of walk catchments as an indicator of accessibility to services has been used by transport planners since the 40’s

State Plan Measures: Planning policy to encourage job growth in centres close to where people live and to provide access by public transport.


Technology changing the game

The 70’s with compass, pencils, roadometre and dot grids..

The 80’s spatial software – distances as the crow fly's from routes with population estimates base on geography.

• the 90’s spatial software – network distances to access points and population based on land use.

Now – real time data via from smart devices, ticketing, GPS infra red detectors, laser scanners, ?

• the 00’s spatial software – network distances, walk times and to access points and population estimated on address points


There are commercial products such as WalkScore ® that will provide a single location, suburb or city a walkablity score based on the built environment and distance measures.

The AURIN Portal walkability tools and guidance on the use and then describes some of the methods of measuring walkability

The Regional Municipality of Halton, Ontario, Canada using ArcGIS model builder have automated the analysis so it is easily repeated

Advances is spatial software and data allow not just catchments but the walkabilty to be assessed


Walkability Rating

The TfNSW requires a strategic tool is to provide a consistent and accurate to measure of walk to assist in identify where infrastructure funding for walking may be spent.

In the Metropolitan Sydney the BTS will use Household Travel Survey data to investigate measures and the correlation with minutes walked per respondent from the HTS.

The rating tool is a strategic tool for use at the local area. It is a coarse sieve of locations.

The tool at this point is Sydney Metropolitan centric.

The majority of the datasets have Australian coverage and are OpenSource


The foundation of all of the spatial tools is the ability analyse proximity, length and associated

attributes.

The spatial data listed is focus on the built environment and demographics. The suggested data have been complied from a literature review on spatial data and walkablity

The data freely available and in multiple formats

Ideally the application would be built and delivered using OpenSource software

Most importantly outputs will be consistent and the evidence transparent

Providing the tools

The NSW government facilitates web services like Spatial Information Exchange and the NSW Globe.

The availability of OpenSource spatial software like GRASS and QGIS allow access to tools and analytics.

Providing the data and or tools through Cloud services such a ArcGIS Online.

Providing the data and or tools through Government agencies such as the E-planning tool.
