1.01 Purpose

The Work Zone Safety and Mobility (WZSM) Rule outlined in federal regulation, 23 CFR 630 Subpart J, requires a policy for the systematic consideration and management of work zone impacts on all federal aid highway projects across all stages of project planning, development, construction and operations.

The WZSM Policy (Michigan Department of Transportation (MDOT) Guidance Document 10177, dated August 24, 2007) was established in accordance with the WZSM Rule outlined in 23 CFR 630 Subpart J, to improve safety and mobility in work zones by reducing congestion and traffic incidents. The policy is in agreement with, and does not supersede, State Transportation Commission Policy 10015, dated September 25, 1996.

The primary goals of the WZSM Rule and WZSM Policy are to reduce crashes and manage congestion due to work zones.

To accomplish these goals, a Transportation Management Plan (TMP) is necessary for consistent consideration of the safety and mobility impacts of work zones, and the development of strategies and plans to reduce work zone impacts on all projects.

A TMP is a dynamic document that provides strategies, elements, and details for managing WZSM impacts during construction, maintenance, permits, and local agency work zones. The TMP is updated and revised throughout the life of the project.

MDOT is committed to providing work zones with the highest level of safety and mobility possible, beginning with project planning and extending through construction and operations. Management and staff are responsible for ensuring the policy is implemented and sustained for safe and efficient travel throughout the State of Michigan.

The specific processes, procedures, and guidelines to support the implementation of the policy are developed and communicated herein. This manual also includes methods for the analysis of crash data, mobility analysis, and work zone process review procedures.

Variations from the policy and this manual may be considered, evaluated, and incorporated into specific projects on a case-by-case basis. Contact the Work Zone Delivery Engineer (WZDE) to determine if a variation may be acceptable
