Up-to-date congestion data are critical for evaluating improvement strategies that focus on mobility and system reliability such as corridor improvements, signal coordination efforts, and deployment of ITS components. This paper describes a tool for measuring travel time and delay along arterial corridors using global positioning system (GPS) and geographic information system (GIS) technologies. The tool is called GPS-Based Evaluation of Travel Time (GETT). GETT uses linearly referenced GPS data and checkpoints along the routes of interest to calculate partial and cumulative travel times, speeds, and delays. The application also measures three elements of intersection delay: control delay, approach delay, and stopped delay. The application produces detailed and summary tabular reports, and output data can be used to generate color-coded maps depicting congestion problems along corridors.
