Welcome to the MN Transportation Research Collaboration Site

MnDOT Research Services wants your ideas for the Local Road Research Board, MnDOT Research Program and Research Implementation Program, and this is where we gather them. Scroll down to see what's new. Register or log in to submit a new idea or vote on the ideas to show your support. (To enter a new idea, click the "Submit New Idea" button, choose your idea's topic area, fill in the online form and click "Submit" at the bottom of the form when you are done.)

The deadline for new research ideas for this year's research RFP was May 11, 2018. Research ideas will be prioritized by TRIG and LRRB in June, and high priority research needs will be developed into research need statements and posted for university proposals in August. The proposals will be prioritized and selected for funding in December.

In December 2017, 27 research projects were funded by TRIG and LRRB. Those project funding awards were posted on the research RFP web site: http://www.dot.state.mn.us/research/rfp.html.

Note that new MnDOT implementation ideas can be submitted at any time for development into an implementation plan and funding request. Your implementation plan will be considered by TRIG at their next scheduled meeting (TRIG is a panel of MnDOT office directors and district engineers.)

Evaluation of Metro Freeway System for Reliability and Resilience

Developing and operating a reliable and resilient freeway network, which can absorb, recover and adapt to actual and potential adverse events, is of critical importance in sustaining the way of life and economic vitality of the metro area. Through the TeTRES tool developed in previous, research could be completed to study freeway network reliability and resiliency which could help MnDOT develop TSMO strategies or corridor ...more »

Evaluation of Curing Effects on Cold In-Place Recycled (CIR) Materials

Cold In-Place Recycling is a rapidly growing rehabilitation and maintenance technology that offers multiple environmental and economic advantages. For these reasons, more and more states and local agencies are applying it for rehabilitation of low-volume roads and highway interstates (i.e., TH110 in the Metro district, 2017). Despite this, there is lack of efficient tools for measuring the uniformity and the as-constructed ...more »

Using Technology to Accurately Count Airport Operations

Many technologies have been deployed to attempt to count the number of aircraft operations at General Aviation airports. Among these are acoustic counters, radio monitors, pneumatic tube, game trail cameras, and manual counts. Each of these technologies has limitations that do not allow truly accurate accounting of airport operations at reasonable cost. This project would develop technology to deploy video cameras ...more »

Impact of Transitway Parking Infrastructure on Mode Choice and Traffic Flow/Volume on Neighboring Roadway Network

What impact does the transitway parking infrastructure have on mode choice and traffic flow/volume on the neighboring roadway network? The term transitway refers to corridors served by fast, reliable, and high-quality passenger transit service such as light rail, commuter rail, and bus rapid transit. Transitways serve high-demand corridors with facility and route improvements that may include dedicated stations and right-of-way. ...more »

Impact of Transitways on Vehicle Use/Travel on Parallel and Adjacent Route Highways and Major Roads

How do transitways impact vehicle use/travel on parallel and adjacent route highways and major roads? The term transitway refers to corridors served by fast, reliable, and high-quality passenger transit service such as light rail, commuter rail, and bus rapid transit. Transitways serve high-demand corridors with facility and route improvements that may include dedicated stations and right-of-way. (Definition provided ...more »

Impacts of Airport Zoning on Land/Home Values

Airport Safety Zoning is required by statute (Chapter 360) in Minnesota for the safety of people on the ground and in the air by preventing incompatible development around airports. Despite this requirement, by one measure only about 50% of the state's airport communities have enacted ordinances that are fully compliant with Minnesota's somewhat stringent airport zoning standards as articulated in Minnesota Administrative ...more »

GNSS Evaluation Toolkit

Advancements in connected and automated vehicles have fueled the demand for technologies that enable high accuracy positioning and navigation such as Global Navigation Satellite Systems (GNSS). One method for using GNSS to generate position solutions accurate to the centimeter-level is called Real Time Kinematic (RTK) positioning which relies on corrections data provided by a network of reference stations. MnDOT plays ...more »

High Density Asphalt Mixtures: Fine Aggregate Mixture Properties for Asphalt Mixtures with RAP

Investigation of Fine Aggregate Mixture Properties for Asphalt Mixtures with RAP Proposal for Idea Scale Program Current research is investigating the compaction of asphalt mixtures using experimental and computational tools, with the goal of increasing the density of newly constructed asphalt pavements. Preliminary laboratory results and numerical simulations using discrete element model indicate that the fine portion ...more »

Assessment of Pedestrian Safety near Metro Transit Stops

Pedestrian fatalities and injuries represent a growing percentage of all traffic fatalities and injuries. These fatalities comprised 10.9% of all traffic deaths nationwide in 2004, but 14.5% in 2013 and 15% in 2015 (NHTSA, 2017). A recent MnDOT analysis found a significant correlation between bus stops and severe pedestrian and bicycle crashes. The metro transitway may influence the interaction between the automobile ...more »

Environmental Field Evaluation of Potassium Acetate

Salts, primarily sodium chloride have been used as a winter snow and ice control chemical for over 50 years in Minnesota. MnDOT alone used 197,417 tons of salt during the 2016-17 winter season, along with widespread use by local governments and private applicators. Due to corrosion issues and environmental impacts to soil and water quality, alternatives to chloride based chemicals have been explored and utilized. Potassium ...more »

Assessing HMA Layer Thickness and Quality using Dispersion Analysis of Lamb wave

MnDOT used FWD to assess pavement stiffness. FWD only gives pavement stiffness at a location, not continuous. However, Lamb wave technology has a potential to obtain continuous HMA stiffness. This is a proof of concept project. The objectives are 1. Demonstrating the robustness of Lamb wave measurement to estimate HMA layer stiffness and thickness using lasers and high frequency data acquisition system; 2.comparing the ...more »

Benefits and considerations of fracture energy-based design approaches

Experimental fracture test methods such as the Disc-Compact Tension (DCT) have proved to be effective tools for discriminating between asphalt mixtures with different resistance to cracking. MnDOT has implemented DCT test on several projects. However, a method is needed to quantify the benefit of fracture energy. The project will advance our understanding of the various mechanisms governing the crack initiation and propagation ...more »
