Drivers traveling the Schuylkill Expressway (Interstate 76) through Montgomery County, Pennsylvania, may notice their commute is getting better, and PennDOT claims for a lot of people, it should be.

The Pennsylvania Department of Transportation says it’s seeing a reduction in both the number of crashes and travel time after launching a pilot program to change speeds along I-76 from King of Prussia to the U.S. Route 1 Interchange in Philadelphia.

The variable speed limit signs were installed along the 14-mile stretch of the Expressway in the spring of last year to help drivers get back and forth faster and safer.

The electronic signs change the speed limit based on live conditions, like weather and congestion. The speed can vary between 35 mph and 55 mph on busy I-76 that serves around 130,000 drivers daily.
