This paper presents a pilot study of conducting an online implementation of DynaMIT, one of traffic estimation and prediction(TrEP) programs developed by an MIT research team with the support from the U.S. Federal Highway Administration, in HamptonRoads, VA, U.S.A. As a first step, a test-bed network was cbefore evaluating the performance of the online implementation of DynaMIT. Based on the online implementation of DynaMIT forthree days, it was found that DynaMIT showed fairly good performance on the estimation and prediction of the sensor counts withthe root mean square normalized (RMSN) error ranges betwen 0.15 and 0.25 for estimations, and 0.25 and 0.4 for predictions. Eventhough speed and travel times showed some discrepancies, further investigations indicated that the performance of DynaMIT can besignificantly improved with adequately calibrated supply parameters.
