MnDOT Synthesis Report: Maintenance and Inspection for Signals, Lighting and Sign Structures

Client: Minnesota Department of Transportation
Audience: MnDOT managers and staff

In this Transportation Research Synthesis, CTC & Associates helped MnDOT’s Asset Management Program and Office of Traffic Engineering gather information from state departments of transportation and other agencies about preventive maintenance and inspection strategies designed to extend the service life of traffic signal, roadway lighting and overhead sign support structures. This quick-turnaround Transportation Research Synthesis presents the findings of that survey along with the results of a limited literature search of relevant national and state practices, research and guidance.
