| − | 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 ([https://www.michigan.gov/mdot/Business/work-zone-mobility WZDE]) to
| |
| − | determine if a variation may be acceptable
