Abstract:
ODOT’s policy for Dynamic Message Sign utilization requires travel time(s) to be displayed as a default message. The current method of calculating travel time involves a workstation operator estimating the travel time based upon observation of high-density vehicle detectors. With the proliferation of cell phone usage and the advent of computer-aided dispatch links from 911 call centers, incident detection no longer requires a high density of vehicle detectors along the highway. Therefore, ODOT’s future freeway management system deployments (Cleveland, Akron-Canton, Dayton-Springfield, and Toledo) will only have a limited set of vehicle detectors for data sampling. ODOT currently utilizes two different algorithms to estimate travel time in its Freeway Management Systems for display on Dynamic Message Signs. These methods may no longer be accurate with limited vehicle detector data. Therefore, innovative methods for accurately calculating travel times are needed to maintain the message sign policy.
