Townsville City Council maintains a traffic model for the entire city.
The following limitations apply to the Traffic Forecast Models:
The Townsville Aimsun Integrated Model (TAIM) is an imperfect representation of traffic information on the road network in the calibration year. The traffic model has been developed using Aimsun traffic modelling software and provides an interpretation of the traffic conditions limited by the modelling processes.
The model has been calibrated against traffic flow data recorded by vehicle detection equipment at approximately 150 signalised intersections comprising over 2175 detection counts, and approximately 150 traffic count sites located across the city.
Model accuracy at any particular location is relative to how close the location is to a calibration point in the model. At a calibration point the model replicates the traffic flows at that location, e.g., at a signalised intersection the model flows and the data recorded by the signals will match in the calibration year. Between calibration points the model becomes less accurate and a process called Dynamic User Equilibrium (DUE) is used to estimate traffic flows based on travel time algorithms.
Future year forecast models assume various structural changes to the road network consistent with Townsville City Councils’ review of the Local Government Infrastructure Plan (LGIP) and the Townsville Growth Model.
Timing of LGIP projects is indicative only and are subject to funding. There is no commitment by Council to implement any infrastructure changes indicated in the traffic forecast models.
Townsville City Council accepts no responsibility for damages, if any, suffered by any party because of decisions or actions made based on data extracted from the model.
