This paper describes select results of a pilot test of automated speed enforcement devices (ASEDs) in Michigan. A mail response survey of drivers (1,209 respondents) showed the general public favors use of ASEDs in select situations, particularly in school zones, in areas where traffic enforcement is dangerous for police, for heavy trucks, and in construction zones. The survey also showed opposition to ASED use on freeways, on bridges, and on "all roads." In general, observed speeders and persons who reported having multiple citations in the previous two years were in greater opposition to the use of ASEDs than the general population.
