Southern Link Road Corridor Concept Design
Transport Modelling
Client: Transport for New South Wales (TfNSW)
Ason Group was engaged by TfNSW to investigate the Southern Link Road (SLR) design and upgrade options to carry out the concept design, environmental assessment, detailed design and staging for SLR. The concept design has been divided into three stages.
- Stage 1 connects Mamre Road to Compass Drive
- Stage 2 connects Compass Drive to Old Wallgrove Road
- Stage 3 connects Old Wallgrove Road to Wallgrove
Southern Link Road is a proposed new east-west corridor that would provide an additional link between Mamre Road, Kemps Creek and Wallgrove Road, Horsley Park.
Southern Link Road is expected to be around 7.5 kilometres long and provides access to the future industrial development that would create employment and economic growth in the surrounding Western Sydney area.
Our work included:
- A review of historical traffic survey data is used to develop base model and validate with the latest SCATS data.
- Develop, calibrate and validate the mesoscopic- microscopic ‘Hybrid’ model in Aimsun of the SLR and surrounding WSEA.
- Develop a base model to assess existing traffic patterns within the study area and identify congestion locations in the study precinct.
- Conduct multi-criteria assessment for the options and construction staging analysis.
- Develop future year scenarios 2031 and 2036 to access SLR options against the ‘do nothing’ road network configuration.
- Develop travel demand management (TDM) strategy to reduce travel demand and redistribute the traffic in horizon years.
- The model provide the inputs and measures required for the Business cases economics, pavement design and environmental assessments.
- The model output informs the SLR development staging and defines road infrastructure upgrades required to mitigate traffic growth.
