The department decided to move ahead after a measure that would have required cities and counties to get department permits before installing new traffic cameras died for this legislative session.
Department Director Paul Trombino says the rules would help as more cities consider using the cameras. The guidelines would require that cities provide data showing that cameras are the best tool to improve safety on the highways.
The department will hold community meetings to get reactions from Iowa drivers. It also will consider legislation as part of the process.
