Work Zone Safety & Mobility Solutions


The Truck Entry Warning System alerts motorists of trucks that are about to merge into traffic. This automated system will detect, through a non-intrusive sensor, trucks that are off road and that are leaving the work zone to enter the roadway. The sensor transmits the information to a Portable Changeable Message Sign (PCMS) or a truck entry trailer with a static sign and flashing beacons, so that the message can be displayed to the motorists downstream.
