ABSTRACT:
A movable barricade for use in controlling vehicle travel through a traffic control locus of a security perimeter, such as the fenced-in boundary often found around a building, a plant, an industrial area, or other infrastructure. Barricades structured according to certain aspects of the invention are capable of disabling forward progress of even large cargo-carrying vehicles, such as 18-wheeled trucks and trailers, or large-capacity tanker trucks. Preferred embodiments of the invention include a high-mass barrier element, such as a concrete Jersey Barricade, adapted to be rolled into a blocking position to obstruct the flow of traffic, and rolled into an open position to permit unobstructed flow of traffic though an access control point. Certain embodiments of the invention also provide control of pedestrian traffic through the locus.
