PCT No. PCT/AU96/00532 Sec. 371 Date Feb. 25, 1998 Sec. 102(e) Date Feb. 25, 1998 PCT Filed Aug. 23, 1996 PCT Pub. No. WO97/08392 PCT Pub. Date Mar. 6, 1997A secure vehicle parking space is provided with an adjustable barrier comprising a post that is located on the floor of the car space at the entry end. The post is movable from a prostrate position to an erect position and then is movable longitudinally of the car space toward the vehicle. A sensor in the post senses the distance of the post from the vehicle to locate the post a predetermined distance from the vehicle. The advantage is that a vehicle of any length can be securely restrained using a single erect post. The system is adapted for use with coin operated or other secure locking mechanisms.
