ADOT adds travel times along I-17 to Flagstaff

If you’re used to hearing those expressed words again and again while driving on Interstate 17 between Phoenix and Flagstaff, the solution is on the Arizona Department of Transportation&rsquo now;s electronic community forums.

As it can along Phoenix-area freeways, ADOT has started posting estimated travel times via I-17 to Cordes Junction, Prescott, Sedona, Flagstaff along with other points of the Valley north.

The test display of I-17 travel times is really a first for a rural portion of the state’s highway system. For ten years, ADOT’s community forums have provided travel times to Valley drivers. Those posted travel times have already been a favorite feature with commuters. “One reason we’re expanding along I-17 is that the winter season make a difference travel times to or from key destinations in northern Arizona,” said Brent Cain, who leads ADOT’s Transportation Systems Operations and Management division. Estimated times that reflect highway conditions can help drivers making use of their travel plans.

On a recent, without weather-related backups or delays because of traffic incidents, a note board north of Jomax Road estimated 120 minutes to visit 125 miles to Flagstaff and 40 minutes to visit 43 miles to the Highway 69 interchange in Cordes Junction.

A forum including the one on northbound I-17 near Sunset Point Rest Area can tell those going to Sedona whether Highway 260 or Highway 179 may be the most effective route. Southbound I-17 community forums can tell drivers whether Highway 169 or Highway 69 may be the better substitute for Prescott.

While travel times posted in the Valley result from ADOT’s in-pavement traffic-flow sensors, the brand new I-17 travel times draw on real-time traffic data from INRIX, a mobility analytics company that helps transportation agencies monitor, manage and measure traffic information. ADOT designed a software program to process this data for I-17 automatically, something that may be used on other busy routes eventually.

“Using data from industry we can expand our capability to support informed and safe travel round the state,” Cain said.
