The best plan I have seen is here in Georgia and Florida. The DOT puts up 6 small signs at almost every exit. They are for food, gas, and lodging. About 1 mile before the exit is one sign for food, one for gas, and one for lodging. All they show is the logo of the available business. The most I have seen is 6 logos on each sign and one occassion there were two signs for food. Once you are on the exit there is another sign for each category with distance to each business. I love them and use them all of the time. I don't even pay attention to billboards any more. Many are out of data so I just ignore them.
