Travel Time Messaging on Dynamic Message Signs - Portland, OR

Federal Highway Administration

Overview

The Oregon Department of Transportation (ODOT) Region 1 office is responsible for the operation and maintenance of Dynamic Message Signs (DMS) and the posting of travel time information to those signs on Portland area freeways. Supervision of such activities is conducted from its Regional Traffic Management and Operations Center (TMOC) located in downtown Portland.

ODOT began supplying travel time information to drivers via DMS in order to provide supplemental "customer service" benefits including: a) helping drivers make more educated decisions concerning route choice, b) reducing trip time related anxiety, and c) improving the public's perception of the usefulness of the DMS (e.g., the public is now provided with accurate travel time data instead of just a message stating "Congestion Ahead," or a blank sign).
