This disclosure describes a vehicle disablement system which includes one or more sensors capable of detecting a vehicle, and one or more vehicle disablement mechanisms. According to embodiments, the one or more sensors are capable of sending a communication to and activating the one or more vehicle disablement mechanisms upon detecting a suspect or target vehicle to disable the suspect or target vehicle. Also described is a method of disabling a suspect or target vehicle, which includes detecting a suspect or target vehicle by way of one or more sensors and sending a communication to and activating one or more vehicle disablement mechanisms to disable the suspect or target vehicle. Further, a vehicle disablement mechanism is also described. The system and method can be used in applications such as counterterrorism, security, and law enforcement.

A vehicle arrestor system includes a ditch box defined by a pair of opposing side walls and a bottom wall extending between the side walls forming a chamber therebetween. A movable plate forms at least a portion of a top wall of the chamber. A mechanical actuator is operably coupled to the movable plate for causing the movable plate to move between a non-actuated position and an actuated position. The movable plate is flush with the road pavement when in the non-actuated position and is not flush with the road pavement when in the actuated position. The vehicle arrestor system serves a dual purpose of arresting movement of a vehicle and providing a notification to a driver of the vehicle to slow down if the vehicle is exceeding the posted speed limit. A plurality of vehicle arrestor systems can be strategically placed in a locked island arrangement.

An arrestor bed for slowing an aircraft overrunning a runway, including an elongated excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio between 1:1.6 to 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.

A support structure, including an excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio of about 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of at least about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.

A method for establishing a runway safety area adjacent a runway, wherein the runway safety area is a cement matrix having a plurality of foamed glass aggregate bodies suspended therein, including mixing cement and foamed glass aggregate bodies to define a composite material, forming the composite material into a runway safety area defining a plurality of foamed glass aggregate bodies suspended in a cement matrix, taxiing an aircraft over the runway safety area and crushing at least a portion of the runway safety area with the aircraft to bleed off the aircraft's kinetic energy, wherein the runway safety area has a crushing failure mode.

A traffic calming device comprising an obstacle which is placed on a road, the obstacle being moveable or deflateable at a predetermined speed or rate so that the obstacle presents a smaller profile to a vehicle driving at or below the speed limit.

A method of slowing an aircraft overrunning a runway, including paving an area immediately beyond the end of a runway with foamed glass bodies to define a bed, covering the bed with a layer of cementitious material to define a composite bed, and crushing at least a portion of the composite bed with an oncoming aircraft, wherein crushing the at least a portion of the composite bed removes kinetic energy from the oncoming aircraft to slow the oncoming aircraft. The composite bed is generally resistant to fire.
