This research investigated travel time estimation by utilizing vehicle detectors as a lesser interval than have been previously used by ODOT and the focus of this study is the area covered by the ARTIMIS program in Cincinnati. By processing simulated freeway loop detector data, travel time estimates have been compared with travel times reported from VISSIM model. An improved methodology was proposed to estimate freeway corridor travel time under congested traffic. Field data were also collected using the floating car method and comparison of the field measured with the estimated travel times was made to show the effectiveness of the improved methodology.
