A4−2: Guide to Establishing Speed Limits in Highway Work Zones

DESCRIPTION:

The Minnesota Department of Transportation (Mn/DOT) has produced a document entitled, "A Guide to Establishing Speed Limits in Highway Work Zones." This document outlines the guidelines, proper layouts, and procedures for implementing work zone speed limits. Mn/DOT used the guide in a training class that they presented throughout the State of Minnesota in 1997−98. Through this training class Mn/DOT has trained over 500 people.

REASON(S) FOR ADOPTING:

Mn/DOT 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 now being implemented and signed more uniformly. This should be effective in making work zones safer for the highway worker 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 UTILIZED:

Minnesota
