Preventive Maintenance and Inspection for Traffic Signals, Roadway Lighting and Overhead Sign Structures

The Minnesota Department of Transportation (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 signals, roadway lighting and overhead sign 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 and inspection strategies, and the criteria used to determine asset replacement. This Transportation Research Synthesis presents findings from a survey of select transportation agencies and a literature search of relevant national and state practices, research and guidance.
