TRAVEL TIME: DOT Using Message Boards

dot_sign

Commuters in the metro found something new along I-235 Wednesday morning.

The Iowa Department of Transportation is now posting travel times on its digital message boards during the morning and afternoon rush hours Monday through Friday.

It displays a slow speed message, when traffic speed is 25-percent or more lower than the posted speed limit. Times are calculated every 20-seconds using existing DOT traffic sensors. The program is only for the I-235 corridor for now.

The DOT plans to expand travel-time reporting across the state.
