Summary
This report evaluates the progress of Michigan’s Traffic Incident Management (TIM) program, specifically assessing the effectiveness of safe, quick clearance strategies implemented since a 2012 baseline study. Conducted by Gannett Fleming for the Michigan Department of Transportation (MDOT) and the Federal Highway Administration, the research aimed to measure improvements in driver awareness of safety laws, assess responder training and coordination, and identify necessary investments for future program sustainability. The study was motivated by the need to enhance roadway safety, reduce secondary crashes, and ensure efficient incident clearance through better public compliance and responder preparedness. The methodology combined qualitative and quantitative approaches. Researchers conducted eight regional workshops with emergency responders, law enforcement, and MDOT personnel, alongside a statewide executive visioning session. These sessions utilized the FHWA TIM Self-Assessment framework to identify strengths, obstacles, and strategic goals. Additionally, the team performed a comprehensive literature review of national TIM best practices and administered a survey to 1,200 Michigan motorists to gauge awareness of the "Steer It, Clear It" driver removal law and the "Move Over, Slow Down" law. This data was compared against results from a 2012 survey of 800 respondents to track changes in public knowledge and behavior. Key findings indicated that TIM training is robust and widely accepted, with strong cooperative attitudes among multi-disciplinary responders. However, significant gaps remain in resource availability and communication infrastructure. The motorist survey revealed increased awareness of safe clearance laws compared to 2012, though regional disparities in compliance and knowledge persisted. Responders identified five overarching goals for the future: improving partnerships, maintaining training focus, leveraging technology, ensuring resource availability, and enhancing program sustainability. Specific needs included better radio interoperability, standardized high-visibility apparel policies, and formalized TIM teams. The study also highlighted the need for improved public outreach regarding detour routing and incident information. The report concludes with a strategic business case for expanding the Mi-TIME program, recommending an annual investment of $14.2 million. This funding allocation covers personnel costs, regional operations, training, and performance bonuses. The authors propose formalizing TIM structures through written agreements and institutionalizing the program to ensure long-term viability. By addressing identified gaps in equipment, communication, and public education, Michigan aims to further reduce incident-related delays and enhance safety for both responders and motorists. The findings provide a roadmap for transitioning from ad-hoc incident management to a coordinated, statewide system supported by dedicated resources and continuous stakeholder engagement.
Key finding
Public awareness of safe, quick clearance laws increased between the 2012 and 2017 surveys, and regional workshops identified five key goals for future TIM program development.
