• Consultation with Council and the wider project team to inform project goals and design intent
• Undertaking extensive traffic/ parking surveys and audit of data
• Undertaking detailed analysis of existing off-street public parking provision
• Assessing future parking demand/ supply in the context of existing parking behaviour and future development
• Recalibration and validation of the 2016 Picton Town Centre Aimsun traffic model based on new surveys undertaken in 2019
• Base Aimsun model considered 7.5km of local road network, including one signalised intersection, 13 priority intersections and one roundabout
• Minimum Aimsun model coded to reflect infrastructure changes at four intersections, as recommended in Council’s 2026 Transport Plan
• Processing of traffic data from the MacArthur Regional Transportation
• Model to understand future traffic demands in Picton town centre
• The proposed CCCP development was then assessed at the 2036 design horizon using the DM Aimsun model
• Results from the Aimsun model were presented in a Traffic and Transport
• Report which was submitted in support of the planning proposal for the town centre redevelopment.
