## Dynamic Message Signs

- Valuable pieces of “real estate”
- Nationwide -4081
- Urban-3300, Rural-781

## A Resource Underutilized

- Non-Incident/Non Roadwork Periods
- Signs are often blank
-     or
- Provide vague information

## FHWA Recommended Practice for DMS

- Travel Time Messages Should Be the Goal as the Default Information Provided to Motorists
- “Blank” DMS are Transportation Investments that are Not Being Fully Utilized
- No New DMS Should be Installed in Major Metropolitan Areas or Heavily Traveled Corridors Unless the Capability to Display Travel Times Exists

## Survey Results

- Percent of TMCs that Display Travel Time by Time of Day
- 23% Both in Peak and Off-Peak Period
- 7% in Peak Period
- 70% does not Display

## Survey Results

- Relative Number of DMS on Which Travel Time Messages are Displayed

## Survey Results

- Reported Public Response to Travel Time Messages
