Pennsylvania Turnpike Commission (PTC) Fog Detection, Traveler Information and Dynamic Traffic Control System PTC Fog Warning System (FWS)

摘要

The Pennsylvania Turnpike Commission (PTC) commissioned a turn-key Fog Warning System (FWS) to eliminate fog-related crashes and to reduce secondary crashes along a 19 km (12 mile) stretch of the Turnpike. The Fog Warning System provides real- time, automated detection as well as appropriate responses to counteract reduced visibility conditions by informing drivers of conditions present and lowering the speed limits to match the reduced visibility conditions.
