PennDOT activates variable speed limit signs along Schuylkill Expressway to help balance traffic https://6abc.com/traffic/penndot-activates-variable-speed-limit-signs-on-i-76-to-balance-traffic/10498920/ via @6abc #transform76 #511paphilly

Why have VSL signs been installed?
The primary goals of the VSL installation are to better manage stop-and-go traffic conditions and reduce the occurrence of rear-end collisions. #Transform76 #511PAPhilly

Why are the VSL signs currently static?
Signs are in a testing phase to ensure they are operating correctly. Speed limits on the signs will remain at 50 mph in Philadelphia and 55 mph in MontCo. Testing phase is anticipated to be 4 wks & speed limits will begin to move 5/10.
