Motorists get travel times on new Pa. road signs

November 17, 2008 5:41:14 AM PST
Lighted message boards are now giving motorists travel times to the next exit on three southeastern Pennsylvania highways. The pilot program by the Pennsylvania Department of Transportation began Monday morning on sections of Routes 202, 30 and 100 in Chester County, about 20 miles west of Philadelphia.

The signs display the distance in miles to the next exit and the average travel time in minutes, updated every 20 seconds. Information is fed from sensors along the road measuring traffic volume and speed. That data is sent to computers that control the signs.

PennDOT plans to follow up on the Chester County program by posting travel time information on nearby Interstate 76, the Schuylkill Expressway, in the months to come.
