In order to support a roadway surveillance system for drivers' aggressions under different road conditions, the research demonstrated in this paper focuses on developing a heuristic methodology on calibrating traffic flow models in real-time. Objectives for this development are high accuracy, high efficiency and high robustness. Techniques like data aggregation and bisection analysis are applied in our approach to ensure achieving these goals and further requirements. Two traffic flow simulation models, Longitudinal Control Model (LCM) and Newell's Model are calibrated by applying our approach using traffic data collected at Georgia 400 highway in July, 2003. Running time for calibrating these two models are less than a second, respectively, and eight different field data samples are opted for experiments to prove this method's accuracy and robustness.
