here's an idea to make it a bit safer.
"The mayor of Berlin's central Mitte district has proposed installing "Verichtungsboxen" -- booths where prostitutes can meet clients -- in the airport site, a bid to improve the safety of the city's sex workers. These include drive-in booths, where customers can meet sex workers in their own vehicles."

sounds good to me, tho a bit more public than a red light district.
