Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS)

Research Team: Prof Carey Curtis (leader), Dr Jan Scheurer, Kristen Bell, Oscar Thomson, Dave Robertson, Sevilla Furness-Holland.

SNAMUTS is an accessibility planning and decision-making support tool developed in a collaboration between Urbanet (Curtin University) and the Centre for Urban Research (RMIT University) since 2007. It is GIS-based and assesses the performance of public transport networks in their urban or regional settlement context. Since 2011, facilitated by an ARC Discovery grant, it has been applied to a total of 26 developed cities across four continents.

The tool enables researchers, transport agencies, consultancies and interested members of the public to assess the interplay between public transport network configurations, performance and service standards and the geographical distribution or clustering of land use activities across a metropolitan area. SNAMUTS determines the level of metropolitan accessibility performance from a user perspective and accepts that different users value different aspects of accessibility according to their specific movement and utility needs. Accessibility thus becomes a multi-faceted inquiry, reflecting a multitude of overlapping challenges concerning the integration of land use and transport planning. The SNAMUTS analysis is based on a set of tasks and measurements that highlight the contribution of public transport network and service levels towards these goals from a range of perspectives:

Research around SNAMUTS has been used to support government decision making on sustainable transport systems and re-structuring of urban form to support public transport systems. To date the tool has been used by state and local government planning agencies in Perth and Melbourne, and during interactive stakeholder workshops in Adelaide, Göteborg, Hamburg and Helsinki. In these practical applications, the focus is on the elaboration of future scenarios for public transport network development and urban growth, whose effects on accessibility can be quantified and visualised through a set of 10 SNAMUTS indicators.

SNAMUTS Applications in Planning Practice

City of Port Phillip, Melbourne, Victoria - September 2015
This research explores the implications on public transport network performance and land use-transport integration of a range of proposed tram service and infrastructure improvements within and affecting the City of Port Phillip. These improvements are currently under consideration by local and state government agencies. Their appraisal in this report is intended to assist the City of Port Phillip in effective advocacy and Public Transport Victoria in prioritising actions. Using the Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS) tool co-developed at RMIT University and Curtin University, the current level of public transport accessibility in metropolitan Melbourne and the City of Port Phillip is examined, based on the existing network and services (correct at February 2015). The ‘Status Quo’ or baseline case is also based on the mix of land uses derived from the 2011 census.

City of Perth, Western Australia – July 2015
The City of Perth (the City) is currently developing and Integrated Transport Strategy (ITS) which will establish Council’s long term transport goals and provide a strategic, informed platform for future decision making. In developing this long term strategy the City wish to develop a research evidence-based understanding of the accessibility provided by the public transport network in Perth. The purpose of this research is to apply the Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS) interactive decision tool to assist in examining the performance of the land use and public transport network in order to inform the development of the City of Perth’s Integrated Transport Strategy. Accessibility is measured at 2015 and for three scenarios: 2031 no action; 2031 public transport committed projects; 2050 accessibility optimisation.

City of Gotebörg, Sweden – October 2014
The purpose of this pilot project is to test the application of the Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS) interactive accessibility tool to assist in examining the performance of the current and future public transport network and land use structure in Göteborg. This research was conducted as part of an Australian Research Council (ARC) Discovery project (DP110104884) and the COST TU1002 project – Accessibility Instruments in Planning Practice. One of the primary objectives of the ARC research is to develop the interactive decision tool (SNAMUTS) in order to assist in examining current and future scenarios for land use and public transport framed around the accessibility of the transport network and the accessibility of place. A second objective is to expand the relevance of SNAMUTS in planning practice and decision support by testing the tool in practice situations. The Göteborg project served these purposes.

Adelaide, South Australia - May 2013
The research team conducted a two day workshop in Adelaide as part of the EU COST Action TU1002 . The objective of the workshop was twofold:

Day one of the workshop comprised a presentation on the current accessibility of Adelaide followed by the generation of planning questions to test. Day one presentation [PDF 4.5 MB]

Day two comprised the response to these questions focussing on a scenario for 2040 for urban development and transport infrastructure.
Day two presentation [PDF 5.1 MB]

Our thanks to Prof. Michael Taylor for hosting this event. The workshop was attended by representatives from practice (state and local government, local consultancies) and local researchers - we thank them for their enthusiastic participation and feedback.

Greater Metropolitan Perth, Western Australia – December 2009
The purpose of this research is to apply the Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS) interactive decision tool to assist in examining the performance of the Greater Perth Metropolitan region's current public transport network framed around the accessibility of the transport network and accessibility of place and the implications for accessibility resulting future development scenarios to 2029.

Greater Metropolitan Perth – Network City Activity Centres, Western Australia – April 2008
The primary objective of the research project was to develop an interactive decision tool (SNAMUTS) to assist in examining scenarios for the future growth of the Perth metropolitan area in activity centres framed around the accessibility of the transport network and the accessibility of place. The SNAMUTS tool enables the quantification of the effect of transport infrastructure improvements and modifications, and of land use intensification, on the accessibility of activity centres and corridors by different modes of transport. The SNAMUTS tool provides an in-depth examination of the potential accessibility by public transport to all centres across the metropolitan area.
