• 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.
