PennDOT is Rolling Out the Next Phase of its $125 Million Congestion-easing Project

This spring, PennDOT will light up 73 "digital variable speed" signs along I-76 between the Pennsylvania Turnpike in King of Prussia and Route 1 on the border of Montgomery County and Philadelphia.

After an initial testing period during which the signs will be static, PennDOT will begin to use an algorithm that monitors weather and other traffic conditions to adjust speeds on the signs in real time to warn motorists. The idea is to reduce speeds to prevent fender benders and keep traffic moving, even if it’s moving more slowly.
