In some cities, most notably New York, homeless people can get free transportation out. Usually it's just bus fare, which is admirably cheap by the standards of government social programs.

Hawaii also. The state of Hawaii has started a program that gives free one-way airline tickets to homeless people who decide they want to leave.

Now if only New York will offer airline tickets instead of bus tickets, the homeless can commute back and forth between New York and Hawaii forever. :)
