We used to have something like this. A civil bizjet terminal was opened on a government owned research airfield which up til then operated military aircraft. It was on the airfield but in an 'enclave' separated by a fence and a pair of gates. There was a road running between the bizjet terminal and the airfield proper. ATC had control of traffic lights and half barriers to control road traffic, and the gates were electrically operated on runners also under the control of ATC. There were two CCTV cameras scanning the gates to ensure the road was clear before an aircraft passed through the gates as the terminal was over a Km from ATC.
