From what I have always understood, the roads in TV were built with public money, hence, they have to have public access, regardless if the gate is "manned" or not. Many of the gates in TV are "manned" during certain hours and not at night. Visitors are stopped when entering so a picture of the license tag is recorded, then allowed to enter. But if the gate is unattedned, there is a button you can push to gain access either directly or by a remote control from a security station.
