Abstract In this project, the researchers implemented and evaluated the TTR models using data from arterials in Jacksonville, Florida. Field travel time data was collected using BlueTOAD (Bluetooth Travel-time Origination and Destination), which integrates vehicle detection and tracking with data logging and data processing. Comparison of model-estimated travel times with field data showed that previous modeling had greatly overestimated arterial travel times. This discrepancy resulted from overestimating the impact of flashing yellow lights during early morning hours and the use of pre-timed signal control, when in fact, all the intersections in the study area used actuated control.
