A5−1: Guide to Establishing Speed Limits in Highway Work Zones

DESCRIPTION:

The Minnesota Department of Transportation (MnDOT) developed a document entitled, "A Guide to Establishing Speed Limits in Highway Work Zones" that outlines guidelines, proper layouts, and procedures for implementing work zone speed limits. MnDOT uses this document in the teaching of its Traffic Control Overview and Supervisor classes. The document is available at: http://www.dot.state.mn.us/speed/pdf/WZSpeedLimitGuideline.pdf.

REASON(S) FOR ADOPTING:

MnDOT developed this document to provide uniform guidelines for the proper application of speed limits in highway work zones. Work zone safety is enhanced with proper use of speed limits throughout the length of a work zone. Proper practice also aids in speed limit enforcement efforts.

PRIMARY BENEFIT(S):

Work zone speed limits in Minnesota are implemented and signed more uniformly. This practice is considered effective in making work zones safer for highway workers and the traveling public.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

The use of this guide is applicable to all highway work zones.

STATE(S) WHERE USED:

Minnesota
