Validation of the TRITRAM traffic network simulation model

The traffic network simulation model, TRITRAM (Traveller Information and Traffic Management), has been developed jointly by the CSIRO Division of Information Technology and the Roads and Traffic Authority of New South Wales in a project conducted by the Advanced Computational Systems Cooperative Research Centre. The model has been designed to communicate with the SCATS (Sydney Coordinated Adaptive Traffic System) control software allowing simulation of adaptive traffic control in real time. The system is particularly aimed at large urban road networks with signalised intersections. This paper describes the procedures for model validation and the results obtained to date. The base data is drawn from real traffic data collected during the commissioning of the SCATS system in Hong Kong. The system is compared on the basis of predictions of queue length and average travel time. The results show a very good match for the prediction of queue length. Further investigation of travel time is indicated.
