An access control module 10 for preventing access of a first moving object to an area located behind the access control module, for allowing access of a second moving object to the area, and for allowing exit of the second moving object from the area, the access control module configured to be used with a selected barrier system 56, the access control module 10 including: a substantially planar base 12, having opposing sides 18, a front 14 facing away from the area and a rear 16 facing towards the area, the base for placing on a ground surface; at least one portal 20 for use by the second moving object when accessing or exiting; at least one link connector 22 having a notional vertical axis, the link connector 22 located at, or near one side 18 of the base 12, and at, or near the front 14 of the base 12, the link connect 22 or configured to accept at least one link 54 for linking the access control module 10 with the barrier system 56, and configured to enable hinged movement between the link 54 and the link connector 22 about the vertical axis; and, at least one interface 96 located at a predetermined height above the base 12 and extending between or within the opposing sides 18 of the base 12, the interface 96 configured to meet with a part of the first object moving in a direction toward the front 14 of the base 12 in a collision, and configured to cause the collided first object and the access control module 10 to become substantially locked together during at least a part of a post-collision time, such that the first object is substantially prevented from pitching post-collision movement and upward post-collision movement, wherein the access control module 10 allows part of the first object pre-collision energy to be partially dispersed as post-collision energy via frictional sliding movement of the access control module 10 with respect to the surface, and, wherein the access control module 10, through the linking of the access control module 10 and the barrier system 56, allows part of the first object pre-collision energy to be partially dispersed as post-collision energy via frictional sliding movement of the barrier system 56 with respect to the surface.
