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.
