Abstract
A vehicle barrier system that prevents “tailgating”. The system may include a control system in communication with a sensor system for detecting a vehicle seeking passage through a gateway, as well as a first and second gate system. The control system receives data from the sensor system indicating the presence of the vehicle and, in response, determines whether the second gate system is closed. When the second gate is determined to be closed, the control system opens the first gate system to allow the vehicle to pass the first gate system and attempts to close the first gate system behind the vehicle after the vehicle passes the first gate system. In response to successfully closing the first gate system behind the vehicle, the second gate system is opened to allow the vehicle to proceed through the gateway. Otherwise, an alarm is sounded.
