If the concern is that an open exit gate will not slow down departing traffic, put small speedbumps there. I have worked at a number of locations with large numbers of entrance and exit gates (like huge seaports). When they can, the gates are left up to reduce the number of cycles and prolong the life of the mechanisms. Entrance gates are almost always left down but these are highly restricted areas.

You can't just put speed bumps on any public road you wish...
