  • The Northern Road Upgrade is part of the Australian and NSW governments’ commitment to foster positive growth in western Sydney through the development of growth centres, employment areas and integrated road transport solutions.  The Northern Road is a key north-south arterial link between Richmond Road, Bligh Park and Camden Valley Way, Narellan, and connects the North West Growth Area, Western Sydney Airport Growth Area and South West Growth Area.

    PDC Consultants was engaged to undertake SIDRA Intersection traffic modelling of the M4 Motorway On / Off ramps at The Northern Road.  The traffic modelling was undertaken to assess the impact of various lane reconfigurations to facilitate construction of the intersection upgrade.  This study included collection and analysis of traffic turn count, queue length and Automatic Traffic Counter (ATC) data.
