Report Date:  01/15/2010

Summary:

The 2009 edition of the Manual on Uniform Traffic Control Devices includes requirements for the management and maintenance of all roadway signs. Management of large numbers of signs can pose administrative and financial challenges for local road authorities. The Minnesota Department of Transportation is reviewing whether the removal of ineffective traffic signs may be part of an overall sign management strategy and has asked CH2M Hill to prepare a best practices guide for removing traffic signs. In support of this work, CTC & Associates was tasked by MnDOT with performing a literature search and synthesis of research demonstrating the effectiveness or lack of effectiveness of various types of traffic signs on local roads, including low-volume roads.
