Access to Service Indicators

Access to Service Indicators

The Access to Services Indicators project will build and make available, through the AURIN Portal, an eResearch tool that can generate four composite indices capable of using spatial data about infrastructure and population distribution to quantify access to services and infrastructure in relation to population and for comparison over time and between different Local Government Areas.


Project Overview

The project will develop, test and make available indicators of Access to Services in Melbourne and Melton municipalities through the AURIN Portal and the supporting user manual and technical report.

There are three ways that Local or State Governments in Melbourne can use the access to services indicators:

  • benchmark the current state of accessibility for services in LGAs and community connectivity;
  • understand where we want the state of accessibility in our communities to go; and
  • help decide tactics to achieve the desired state, with the community and partners.

Project Outputs

The project will deliver tools that will create the following indices:

  • Index of infrastructure availability uses catchments in relation to population size for each type of facility (for example, school) and takes into account the number/length/area of facilities available within standardised spatial units, relative to a benchmark, gives a number that shows which ‘cells’ are better ‘endowed’ than the others.
  • Index of proximity, which is a measure of accessibility to a given set of facilities/services distributed over a defined area (e.g. an LGA) in terms of physical distance.
  • Index of service accessibility considers the different levels of standards of physical accessibility (disability access provided by Census of Land Use and Employment (CLUE) Data, and topographical/gradient data from the topographical layers on Vicmap Data) of facilities in the municipality and which ones City of Melbourne facilities meet.
  • Unrealised Potential Quotient considers infrastructure availability and compares with the relevant population to return which ‘cells’ are over supplied with facilities and therefore can perhaps accommodate more population; and which ones are undersupplied, thus needing more facilities. The index is based around the SA1 or mesh block population the nearest facility is serving, rather than a geographically based catchment. Planning guidelines can help inform these population catchments.
