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.
Innovative Contracting Provides Flexibility to Customize Project Results
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, @MichiganDOT is constantly on the lookout for ways to improve the state’s infrastructure with nonmotorists’ needs in mind. This #MDOTResearch 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 #MDOTResearch 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.
MDOT Research Contributes To Driverless Cars
March 02, 2022
A recent BBC article, How Driverless Cars Will Change Our World, highlights the research being completed at Mcity to help further develop the Autonomous Vehicles, or driverless cars. Did you know, MDOT has contributed $3 million in research funding to the facility? Learn more about the research project behind the funding by visiting the link below.
Measuring the Effect and Value of Intermediate Diaphragms on Bridges
February 10, 2022
A new Research Spotlight highlights MDOT’s efforts to determine when intermediate diaphragms should be used for stability in certain precast concrete beam bridges. Modeling data will help MDOT’s bridge designers decide when and what types of beams require extra lateral support.
MDOT Prepares its Workforce for Emerging Transportation Technologies
February 03, 2022
A highly trained and specialized transportation workforce will help MDOT make the most of emerging technologies for years to come. A new MDOT Research report forecasts the skills that will be needed and recommends strategies to retrain current staff and recruit new workers to meet the demands of the future.
New Standards Foster Success Roadside Planting
January 06, 2022
Grassy slopes along Michigan’s urban freeways once posed safety hazards and logistical challenges for MDOT maintenance crews. But thanks to new MDOT Research that shows just what to plant and how to achieve great results, these areas can become useful green spaces that reduce erosion, keep pollutants out of Michigan’s waterways and practically eliminate the need for maintenance.
