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. Register or log in to submit a new idea or vote on the ideas.

New research ideas were prioritized in June by TRIG and LRRB for their annual university research request for proposals. (TRIG is a panel of MnDOT office directors and district engineers.) The list of research need statements for the RFP was finalized in July, and the RFP was posted on August 1, 2016, ( http://www.dot.state.mn.us/research/RFP/FY2018/index.html ) with proposals due September 14. Funding decisions will be made by TRIG and LRRB in December.

New implementation ideas can be submitted at any time for development into an implementation plan and funding request. MnDOT TRIG selected 16 research implementation plans for $1.6 million in funding at meetings in March and September, 2016. (Click here to read the implementation project guidelines PDF.)

Use TomTom trip data to improve accuracy of LRS data

As people drive with a TomTom (or similar device) they generate location data. Using big data analytics this trip data could be analyzed to find lane centerlines which in turn could be used to supply updated centerlines for the Linear Referencing System (LRS) - the replacement for the GIS BaseMap. The result should be a much more accurate GIS road network than the current +/-40 feet. This method of determining a more ...more »

Evaluation of Central Traffic Signal System and Best Practices for Implementation

This summer MnDOT is exploring and implementing a new central traffic signal system for controlling all traffic signals in its jurisdiction. Currently most of MnDOT’s files are stored within Synchro files. While Synchro is good for analyzing delay and coordinating signals, it is not suitable for large scale traffic simulations and travel demand models that are becoming more common place as we attempt to analyze congestion ...more »

Why is this a priority and what are the benefits for the State/County/City? :

Traffic signal information is a precious commodity simply because they require effort saving and maintaining the information. Few commercially available systems exist and most are dedicated to specific brand of controllers. The system MnDOT is implementing is a combination of commercial software and open source applications developed by Texas DOT and Utah DOT. Transferring the current signal information and setting up a system that will serve efficiently all stakeholders is essential for gaining the most from this investment.

Examining the efficacy of bulbouts/curb extensions for pedestrian safety

Curb extensions or bulbouts are becoming increasingly popular in pedestrian dense areas and pedestrian safety and countermeasure guides. They limit the distance by which pedestrians must cross the street, reducing their exposure to vehicles. Moreover, they calm traffic and place the pedestrian closer into the driver's line of sight without requiring them to enter the roadway. Their implementation numbers, however, are ...more »

Why is this a priority and what are the benefits for the State/County/City? :

The increased implementation of curb extensions/bulbouts may have the potential to reduce pedestrian involved crashes and calm traffic at non-signalized intersections. Defining the optimal curb extension size may allow more efficient use of funds by avoiding over-building curb extensions beyond their minimal required size for efficacy. Curb extensions may also limit conflict points at intersections where wide lane widths encourage drivers to pass left-turning vehicles on the right which place pedestrians at even greater risk.

Regulatory requirements are being put in place for evaluation of soil vapor intrusion as part of the environmental due diligence investigation process. These requirements (pertaining to risks associated with potential release of volatile and semi-volatile organic compounds to soil and groundwater) can pose significant new challenges in the development and delivery of transportation projects. The research, as proposed (using soil vapor monitoring results), will evaluate the association between soil and groundwater contamination by release of volatile and semi-volatile organic compounds . This research will help inform guidance for transportation projects in development pertaining to risk management for potential releases of volatile and semi-volatile organic compounds via soil vapor intrusion and with input from the MPCA.

MnDOT has deployed the Rural Intersection Conflict Warning Signs (RICWS) to reduce the fatal and serious injury crashes at rural non-signalized intersections. RICWS provide supplemental warning to motorists approaching some high crash risk intersections. Considering the reports received on the excessive excitation and even blow over of the existing RICWS due to wind, there is an urgent need to evaluate the structural vulnerability of them and identify the required modifications. This will not only improve the public safety, but also help the districts' maintenance groups to save a tremendous amount of resources. Furthermore, the ultimate success of the RICWS deployment program will be ensured throughout Greater Minnesota.

With its data driven approach, various numbers representing, facility condition, operational deficiencies and site condition will be placed before the committee. A consolidation of these numbers into one, two or three values will assist the committee in choosing priority projects. Without these numbers, prioritization will most likely be based less on data and more on other mitigating factors. A Fuzzy Logic approach could be formally implemented and, if proven successful, could be used much like the Monte Carlo scenarios are used in project management.

This is important whether it is dealing with district headquarters, truck stations, salt sheds, cold storage or warm storage. If we cannot clearly explain this element as described, we will have an imbalance and an increasingly difficult time explaining to our constituency the various site issues.
