Abstract
A barrier for the control of access of vehicles through a roadway, which uses stored mechanical energy to place the barrier in one of three states, one a blocking position and two non-blocking positions. The mechanical energy is derived from the weight of the vehicle as it passes over the apparatus. The activation of the barrier can be controlled by remote control at will, time-independent from the passing of the vehicle over the apparatus.
