摘要：	In recent years, some cities in South Dakota have experienced an increased frequency of legal inquiries involving accidents at signalized intersections. Currently, the South Dakota Department of Transportation (SDDOT) does not have a qualitative means to systematically track work that occurs on traffic signal systems or a reliable means to retain records of such work. SDDOT recognized the need to develop a reliable means to verify, track, review, and record an inventory of traffic signal maintenance along state routes, and to produce a set of improved signal maintenance and management procedures. SDDOT through its Office of Research initiated a research study to formulate new policies, agreements, and procedural standards for effective management and maintenance of state highway traffic signals. The research project involved a workshop to provide local and national insight; a review of SDDOT's existing policies, agreements, and procedures; and surveys of maintenance and management practices, as well as computer system needs at other state departments of transportation with similar operational needs to South Dakota. Using the information compiled in the research effort, the study team identified fourteen issues and formulated seven specific recommendations that include development of a maintenance inspection checklist, a final acceptance punch list, revised maintenance agreements, a comprehensive policy and set of procedures for traffic signals on state highways, a traffic signal inventory and maintenance database, and updates to the existing standard specifications. The study team also defined the system requirements, opinions of costs and system benefits, and implementation for a Traffic Signal Management and Maintenance System.
