The intent of this report is to provide a multi criteria analysis of several route options for the AdeLINK Tram network, including the routes as per the Integrated Transport and Land Use Plan (ITLUP), 2015. MCA processes are often applied by State Government Departments and Treasuries to assess project options. This report does not contain any modelling, or engineering data and as such the AdeLINK routes are only stated as potential options. AdeLINK has the potential to attract investment, boost economic growth and encourage urban renewal and jobs, and bring residents and visitors to the city centre. Providing high quality public transport services will also help drive market demand for residential development in the CBD, inner and middle metropolitan Adelaide. In 2013, the development of the Integrated Transport and Land Use Plan (ITLUP) involving 2,500 participants stated they support trams as a first priority (83% of inner and 78% of middle suburban residents). Planning for AdeLINK forms part of the overall electrification of public transport in Adelaide. The study comprises several key steps before concluding with a detailed business case for delivering the AdeLINK tram network (as shown in the diagram below). This is an essential process for establishing the rationale for funding options. The first step, an extensive multi-criteria assessment (MCA) process to assess route options, is now complete and contained in this report. It involved the testing of the original AdeLINK tram network against other potential routes identified in conjunction with Council officers through consultation and workshops. The MCA Summary Report summarises the routes assessed in the MCA, providing guidance as to the route options to be taken forward to the Design Labs and Community Open Days. The results are also presented as standalone studies for each corridor. Criteria are unweighted to comply with Infrastructure Australia requirements. It is important to note that the MCA is one step in the process, and will assist in determining the final preferred routes for AdeLINK. The next phase of the study involves Design Labs, which will explore the integration opportunities between land use, street attributes and tram corridor planning (e.g. station locations) with Council staff and the community. This will provide a framework for more detail planning of the tram lines including stop locations, and identifying constraints and opportunities that will inform the design of each corridor. Following the Design Labs, a number of studies will commence in February 2017 to model the urban development outcomes (patronage demand); develop the operation framework of the tram system, including potential stabling options; assessment of road traffic operations and integration with bus and train services; and potential road and track layouts, including the location and style of tram stops within an urban design framework. 1 AdeLINK Multi-Criteria Analysis Summary Report This ‘Summary Report’ provides an overview of the AdeLINK light rail project, outlines the Multi- Criteria Analysis (MCA) process, a summary of MCA results, as well as some of the project’s contextual framework. Multi-criteria decision making processes have become increasingly prominent in strategic decision making for investment opportunities across a broad range of projects, from environmental preservation, development, infrastructure delivery and so on. It involves a multi-stage process of specifying options to be assessed, defining key objectives/themes and criteria, choosing measures to be scored and choosing the best option to move forward with. For the AdeLINK light rail project: 5 themes, up to 19 criteria and up to 45 measures made up the MCA, dependent on the context (suburban link or CityLINK). This process is outlined in Figure 1 (below) and Figure 2 (overleaf). The original routes identified for the AdeLINK light rail network were prescribed in 2015 by the State Government in their ‘Integrated Transport and Land Use Plan’ (ITLUP) and have been public knowledge since. As a result, these corridors may have already formed a basis for local and state government policy reviews and changes, infrastructure investment and development. Therefore, these routes were each considered as options for their respective AdeLINK corridor MCA. To ascertain additional route options, planning officers and managers from each local government Council through which the ITLUP corridors passed were invited to attend an interactive workshop on 29 June 2016. Facilitated by the Project Team (InfraPlan and SA Government), the goal of the workshop was to come up with route alternatives in addition to the ITLUP route for the MCA. The details of the routes discussed at this workshop are provided in Appendix B of this report. MCA Criteria and Measures were also presented to Council officers for input and refinement. Figure 1: Overview of the suburban AdeLINK MCA process. 2 AdeLINK Multi-Criteria Analysis Summary Report The MCA criteria and measures were refined for analysis of the CityLINK options, due to several factors, including: The ‘loop’ configurations all within close proximity meant that theoretical walking catchments significantly overlapped, encompassing much of the City centre and would yield the same results for some spatially assessed measures making the MCA less effective. This was overcome by reducing the common walking catchment to 300m to allow for variance in the comparative analysis. Since ITLUP, Frome Street has been designated as a bicycle corridor through the City. It is unlikely a tram would be a suitable addition to the street. Many measures not being applicable in the same way as for the suburban links, i.e. as commuter corridors to the City centre. This refinement was undertaken on the 12 January 2017 during a workshop with the Project Team (InfraPlan and SA Government), along with transport and planning staff from the Adelaide City Council. Outcomes of this workshop included determining final CityLINK route options and appropriately revised criteria and measures. Figure 2: Overview of the CityLINK MCA process. Subsequent analysis
