Dade County, by a master plan adopted under authority of the so-called Home Rule Amendment to the Florida Constitution, has undertaken total control of traffic both in the unincorporated and incorporated areas of the county, thereby relieving the municipalities of responsibility for damages resulting from faulty or defective traffic control devices. See A.L. Lewis Elementary School v. Metropolitan Dade County, 376 So.2d 32 (Fla. 3d DCA 1979).
