Research in Progress Update

August 02, 2022

The newly constructed Network Arch Bridge for Second Avenue in Detroit made its move to its permanent location over I-94 starting July 22nd and ending on July 29th. Research Administration worked with Western Michigan University to install a monitoring system studying the stresses on this structure during construction, the move, and after construction is complete. Our research project, Operational Baseline and Structural Health Monitoring for the 2nd Avenue Network Arch Bridge, will help answer questions about how this one of a kind structure performs.

Tools to Protect Coastal Roadways from High Water

July 28, 2022

As water levels in the Great Lakes rise, coastal roads and other infrastructure in Michigan are at risk of damage from flooding and erosion. MDOT has a range of options at its disposal for mitigating the impacts of these hazards, from temporary strategies such as sandbagging to long-term solutions like redesigning the roadway. New research produced a decision guide and other tools to help the agency identify where intervention is most needed and which investment will produce the greatest benefits.

Risk Management Tools Help MDOT Deliver Projects on Time and on Budget

May 26, 2022

Thoroughly assessing and managing risk is critical for keeping construction projects on time and within budget. To make sure the risk management process goes as smoothly and efficiently as possible, Michigan DOT initiated new MDOT Research to discover the tools and techniques used by risk managers across the country. The insight guided researchers as they developed a new and improved set of customized tools, documents and guidance to ensure MDOT’s construction projects are on track to save time and money.

Benefits of Dynamic Message Signs on Driver Behavior and Traffic Flow

May 19, 2022

Dynamic message signs can be updated frequently to give drivers real-time updates about crashes, lane closures, inclement weather, and other relevant information. New MDOT research provides insight into the length, display duration and wording of effective messages so that drivers receive the info they need to make safe decisions in real-time. With greater understanding of how dynamic message signs should be used to get drivers’ attention, MDOT can maximize its budget and keep traffic moving safely.

Evaluation of Dynamic Speed Feedback Signs on Freeway Interchange Ramps

May 05, 2022

Slowing down and adhering to posted speed limits are keys to reducing deadly crashes, especially at freeway exit ramps. New MDOT research shows that targeting custom messages from dynamic speed feedback signs can be a powerful life-saving tool, alerting drivers when they’re going too fast and reminding them to lower their vehicle’s speed around curves.

Updating Best Practices to Keep Pedestrians and Bicyclists Safe

April 28, 2022

Bicyclists and pedestrians made up about 20% of all traffic fatalities in Michigan in 2020. To make roadways safer for these vulnerable users, Michigan DOT is constantly on the lookout for ways to improve the state’s infrastructure with nonmotorists’ needs in mind. This MDOT Research project identified and documented a variety of design strategies and technologies that have worked well in other communities across the country. That info, combined with input from stakeholder groups across the state, will ensure all road users are considered in decisions involving Michigan’s transportation system.

Evaluating Safety and Traffic Improvements Along Michigan’s First Flex Route

April 14, 2022

The 9-mile stretch of US-23 north of Ann Arbor is Michigan’s first flex route, but given its success it likely won’t be the last. With nearly 70% of users reporting their satisfaction with the route’s technologically advanced traffic mitigation strategies, MDOT now has a prototype for adding flex routes to other congestion-prone roadways in the state.

Innovative Contracting Provides Flexibility to Customize Project Results

April 07, 2022

MDOT’s innovative contracting program provides incentives for contractors to meet certain objectives – from completing projects more quickly to getting jobs done with less travel disruption – and rewards professionals who come up with thoughtful, creative solutions. New MDOT Research shows which strategies work best to achieve the desired results, leading to greater innovation and increasing efficiency on projects across the state. 


Restoring Sloped Areas Along Michigan's Urban Freeways

March 24, 2022

High winds, poor soil, pollution and steep terrain all contribute to a harsh and hard-to-grow environment along Michigan’s urban highways. Turf grass has traditionally been the go-to greenery solution, but its high-maintenance needs and short root system make it less ideal for these sloped areas. Determined to create green spaces that can prevent erosion with less upkeep, MDOT conducted a multi-year study that identified a variety of plants and installation practices that can result in beautiful and beneficial landscapes in even the toughest environments.
