The literature seems to indicate that the use of ASE systems does not appear to violate any constitutional rights of drivers when implemented in accordance with state and local ordinances. Operational experience with ASE equipment to photographically enforce traffic laws is presented in this synthesis. Areas of discussion include the range of enforcement strategies used with ASE equipment, the trends in enforcement strategies, some operational constraints associated with the use of ASE and red-light equipment, and several reliability and maintainability issues originating from pilot tests and operational experience with the equipment. Various issues arise with regard to processing citations emanating from the use of photographic enforcement of traffic laws. There are also legal and acceptability issues that surround the use of photographic enforcement of traffic laws.
Limitations imposed by law are obvious.
However, the opinions expressed widely by citizens, public interest groups, and governmental authorities such as prosecutors, judges, and police strongly affect the acceptability of ASE programs. These opinions result in policy and strategy requirements that limit the ways in which ASE is carried out. The success of long-running ASE programs in several U.S. cities is due, in large part, to widespread acceptance by the public and various community agencies. A number of attempts have been made to assess the impact of ASE enforcement on speed limit compliance and traffic safety. The data presented in the literature indicate that the use of ASE devices to enforce speed limits will reduce the incidence of speeding to a certain extent.
