Construction Project Traffic Impact Analysis Methodology and DTA Model Validation

MnDOT has been working toward better understanding of traffic impacts and Road User Costs associated with reduced system capacity during construction activities. In an effort to quantify those impacts, a Dynamic Traffic Assignment (DTA) / Mesoscopic Travel demand model was developed within the DynusT/DynuStudio software platform. This model has been useful for quantifying these impacts among various construction phasing ...more »

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

There is more emphasis and desire for MnDOT to minimize traffic impacts relating to construction projects placed on system users. To effectively doe this, we need to continue to refine and improve the tools the improve our capabilities of analyzing the trade offs made between minimizing Road Users Costs and Construction Costs. This project could help us move us toward improving our effectiveness in balancing these tow competing goals.

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

The loose nuts in over 19% of large anchor bolts of the overhead sign and HMLT support structures has created MnDOT maintenance and inspection problem. AASHTO and FHWA guidelines allow DOTS to inspect OH supports and HMLT at the frequency of 5 years. With so many loose bolt nuts, it will need almost annual inspection for over 2000 OH signs and almost 500 HMLT. This also causes the public safety concerns. The results from the current research project basically has pin-pointed the causes of the loose nut problems and following the proposed guidelines and specifications in construction and maintenance can help in eliminating or minimizing this kind of problems. This will decrease the needs for more inspections and maintenance work and save MnDOT costs in traffic control, bolt inspection and retightening, and all related work. It will also improve the public safety in the loose bolt nut concerns. All state counties and cities can also be trained and benefited from this.

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

Volunteer drivers are an important part of the transportation network, support public transit services and fill a gap for residents in Greater Minnesota by providing trips that are not cost effective for public transit providers. The number of volunteer drivers is declining for multiple reasons. There is no 'back-up' plan for how to deliver these transit trips. This issue is a high priority as it requires time to both understand the potential solutions and work with drivers to implement the new model.

Non-invasive road sensors in RWIS and AVL systems

Implement non-invasive road sensors in RWIS and AVL systems.

Idea Champion - Who at MnDOT/LRRB? : Joe Huneke

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

Current passive road sensors are imbedded in the road surface. Whenever there is a construction or maintenance project that impacts the road surface (mill and overlay, sealcoating, patching, etc.), the imbedded sensor must be replaced. This, and periodic RWIS site and sensor maintenance, requires lane closures and cutting the road surface to install the sensor and cables. The non-invasive sensors are attached to the RWIS tower or a pole near the roadway and uses laser technology to read the road surface temperature and condition; subsequently, future road projects do not impact the sensor and periodic maintenance does not require lane closures.

Integrating Climate Change Vulnerability Metrics into BRIM and TAMS

In 2014, MnDOT conducted a pilot project to better understand the vulnerability of the state’s trunk highway system to flash flood events. MnDOT developed asset vulnerability scores for bridges, large culverts, and pipes in Districts 1 and 6 using a series of weighted metrics. This project will build on the pilot with the goal of integrating key metrics from the 2014 study into decision-making at the agency. To achieve ...more »

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

Minnesota’s climate is changing, including the frequency of larger rainfall events. Understanding how climate change impacts MnDOT’s assets will help identify infrastructure that may be more vulnerable to flooding and other issues that could impact public safety and associated cost to MnDOT.

The FAST Act requires states to consider improving the resiliency and reliability of the transportation system in planning and programming as well as developing risk-based asset management plans. At the state level, the Statewide Multimodal Transportation Plan includes a System Stewardship strategy to proactively identify risks to the transportation system in order to prioritize mitigation and response activities. The SMTP also includes a short term work plan item to identify vulnerabilities and assess risks to the transportation, specifically referencing the changing risks of flooding.

This project will provide staff with new information to help mitigate risks to our statewide infrastructure.

Unmanned Aircraft Systems (UAS) - Metro District Bridge Inspection Implementation

Drones for bridge inspection research has been completed by MnDOT in multiple phases since 2015. As of summer 2017, Phase III of this research began using the senseFly albris and the Flyability Elios, a collision-tolerant drone more suited to confined spaces such as box girders, culverts, or areas that are difficult to access. Due to the success of this research, MnDOT Metro District purchased the Elios drone to supplement ...more »

Access restrictions to bridges for inspection have been a main issue in the Metro District for decades. The implementation of drones for bridge inspection will allow inspectors to gain access to critical bridge components and document current conditions that otherwise have not been thoroughly documented in the past. With this access gained, quality of bridge inspection data will improve and will also improve safety by reducing traffic impacts.

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

Smart parking management is key to any regional travel demand management program. The State Capitol Complex is a job center which generates thousands of trips on Twin Cities roads at peak demand times. Demonstrating the value of data-driven parking management, as opposed to investing millions in additional supply, allows the State and the metropolitan region to promote such strategies to other major regional employers. What is learned from this pilot will inform parking management decisions all of the state.

Priority to allow maintenance to perform all-season work operations and construction to stage within restricted footprint, regardless of equipment type. The benefits are temporary work in wetlands and other soft soils that prevent compaction, allow winter tree removal for endangered bat avoidance, repairs to noise walls and other infrastructure in wet areas. This has statewide benefits for all road authorities for construction and maintenance of the infrastructure, regardless of season and soil type and will enhance financial effectiveness by allowing both work and meeting environmental commitments..

Spatial Analysis of Agriculture Supply Chain to Assess Transportation Impacts

Efficient agriculture movement is critical to Minnesota’s economic health.

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

As rural and urban roads assume a more exaggerated responsibility for connecting agricultural products to the market place, local freight planners are increasingly seeking informed, innovative solutions to address the growing industry’s transportation needs.

Outcomes of this study can inform MnDOT district and strategic freight network investments. Specific potential benefits include:

-identification of trends in specific districts of the state, that can inform local decision making, such as roadway improvement priorities

-identification of statewide trends, that can inform strategic freight investments

-provision of maps than can be used to facilitate a broader understanding of agriculture supply chain and transportation implications, including among the public and policy makers.

The way that slope paving is currently done, the panels are poured in vertical strips and from the top down. With every other one being poured, the material where the contractor is working gets disturbed and never gets recompacted and the rebar doesn't get incorporated into the concrete. With the way that I'm implemting the panels is to place them from the bottom to the top and left to right. Also, you would be able to remove the panels if there is a problem under the panels. It would also take you less time to do a section of slope paving.
