ABSTRACT:
A work zone intrusion alarm system which sounds a siren to warn highway workers in the event a vehicle enters a work zone. Workers may thus react to errant vehicles in time to avoid injury. The work zone intrusion alarm system is composed of a series of pneumatic sensing lines arranged within a highway work zone adjacent a perimeter separating the work zone from oncoming traffic. The sensing lines are connected at junction boxes which include pressure switches. A warning alarm including a siren is activated by the pressure switch upon the compression of a sensing line when driven over by an errant vehicle.
