Abstract: A vehicle barrier deployment system comprises a base member, at least two lifting members, at least one barrier member, and an actuation assembly. The lifting members are pivotally secured to the base member, and are operable to be selectively raised and lowered in a vertical direction relative to the base member. The at least one barrier member is in communication with the lifting members, and is configured to stop a moving vehicle when the lifting members are in a raised position. The actuation assembly is in communication with the lifting members, and is operable to selectively raise and lower the lifting members by moving at least a portion of each of the lifting members in a direction transverse to a traffic lane. The barrier member may comprise chains, a guardrail, or other structures. The system may be mobile or may be fixed (e.g., embedded in ground) in a particular location.
