This paper introduces a model to estimate average link travel time of signalized arterials using data obtained from detectors in Sydney Co-Ordinated Adaptive Traffic System (SCATS). The proposed model makes use of detectors at the upstream stop line of a link to capture the arrival of vehicles, and use a platoon dispersion model to project the vehicle arrival times at the downstream stop line. Using the vehicle departure patterns obtained at detectors at the downstream stop line, the average link travel time is then estimated. The accuracy of the proposed model has been tested, by means of microscopic traffic simulations, for link lengths between 300 m to 800 m, and at different urban street level of service. Results indicate that the proposed link travel time estimation model has an average absolute error of 2.26 sec.
