Traffic flow modelling from Zenith model covering Sydney, the Central Coast, Hunter and Wollongong regions. The model simulates the interaction of every traffic zone to every other traffic zone in a model area, with consideration of where, when, why and how everyone travelled. Most recent publicly available traffic counts from state and local governments are then used to produce Zenith traffic estimates. Estimates may contain aberrations, for instance, due to seasonal variations, weather conditions or public/school holidays. A matrix estimation process is used to fine tune the simulated traffic volumes to that of the traffic counts.
