The Kosciuszko Road Toll Booths Relocation project involved upgrading the National Park entry toll collection facility to relieve traffic queues up to 8km long. Using AIMSUN microsimulation model, Brown Consulting developed a concept for the new facility at a disused service station at Sawpit Creek, as well as the detail design. The whole process from the start of microsimulation to the opening of the facility, including all approvals and the construction, took only five months.
