Abstract:

The MnDOT Asset Management Program and Office of Traffic Engineering are seeking information about the state of the practice in preventive maintenance and inspection strategies designed to extend the service life of traffic signal, roadway lighting and overhead sign support structures. MnDOT is particularly interested in the expected service lives of these roadway assets, preventive maintenance and inspection activities and schedules, cost–benefits associated with preventive maintenance strategies, and criteria used to determine asset replacement. This investigation surveyed state departments of transportation (DOTs) and other transportation agencies that share similar climatic and environmental challenges that are faced in Minnesota, and transportation agencies that emerged as leaders during a preliminary literature review. This Transportation Research Synthesis presents the results from the survey and review of documents shared by survey participants. Results from the limited literature review of state and national research on these practices and the quantification of the benefits of such practices have augmented some of the information gleaned from survey respondents.
