SNAMUTS - Indicators by Areas (SA1) 2021

This dataset presents the footprint of Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS) indicators by area. The data spans the year of 2021 and is aggregated to Statistical Area Level 1 (SA1) geographic areas from the 2021 Australian Statistical Geography Standard (ASGS). SNAMUTS Australia is a multiple indicator tool to assess public transport network performance and land use-transport integration in Australia's five largest metropolitan areas (Adelaide, Brisbane, Melbourne, Perth, Sydney), at SA1 level and for specified activity nodes in the census years 2011, 2016 and 2021. SNAMUTS is a decision-making support tool designed to inform strategies for public transport infrastructure and service improvements, land use intensification and overall metropolitan strategic planning. It also allows for timeline and city-to-city comparisons on public transport performance and accessibility indicators between about 30 cities on four continents. SNAMUTS has been developed and refined with funding from the Australian Research Council (DP110104884), the European Science Foundation (COST TU1002), the Cities of Melbourne, Manningham and Perth, internal support through RMIT University, Curtin University and University of Melbourne, the Sustainable Built Environment National Research Centre (SBENRC), AURIN and in-kind support by the University of Porto, Goudappel Coffeng, University of Amsterdam, University of Gothenburg, Norwegian University of Life Sciences, Western Norway University of Applied Sciences, Concordia University and University of Westminster. These are known as the eight key SNAMUTS indicators, they include: - Transfer intensity (degree centrality) - Ease of movement (closeness centrality), - Geographical reach of public transport journeys (30-minute contour catchment) - Spatial concentration of public transport journey paths (betweenness centrality and transfer propensity) - Flexibility of movement (nodal connectivity) - Future-proofness of the network (nodal resilience) - A composite index for overall public transport accessibility. It is based on public transport network and timetable information available publicly through transport agencies (Adelaide Metro, Translink, PTV, Transperth, TfNSW) and ABS census data (usual residential population and journey-to-work destinations) for the three years (2011, 2016, 2021). This data can be viewed in conjunction with the corresponding routes dataset: "SNAMUTS - Route Segment (Polyline) 2021". For more information, please refer to the SNAMUTS website.
