Idea Champion - Who at MnDOT/LRRB? : Tim Andersen, Pavement Design Engineer

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

Research has demonstrated that geogrids may save money by extending pavement life, reducing the required pavement thickness, or eliminating the need for extensive subgrade excavations. The ability to simulate these improvements in our pavement design procedures will enable designers to quantify the benefits of using geogrid in pavement designs and select the most economical design.

Modulus and Dynamic Cone Penetrometer Data Collection for Full-Depth Reclamation Projects

Obtain backcalculated moduli and dynamic cone penetrometer (DCP) results on existing full-depth reclamation (FDR) projects for implementation in MnPAVE-Flexible pavement designs. Determine average modulus values and standard deviation for FDR materials. Evaluate the relationship between DCP and modulus for FDR materials. A predictive model for FDR modulus will provide another tool for pavement designers.

Idea Champion - Who at MnDOT/LRRB? : Tim Andersen, Pavement Design Engineer

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

The current FDR modulus in MnPAVE is based on very limited data and appears to be overly conservative. We need more data to better represent the current FDR materials in use. Higher confidence in modulus values enables more economical pavement designs.

Idea Champion - Who at MnDOT/LRRB? : Kevin Western

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

Asset management and maintenance of bridges requires knowledge of not only up front repair cost, but the expected life. This project will give direct feedback on different repair and preservation techniques implemented 20 years ago on a heavily traveled bridge that remains in service. This project is important because when repair techniques are developed the big uncertainty is the predicted life estimate. There is very little long term data to substantiate repair life estimates. This study will show the effectiveness of different repair strategies from actual bridge repairs performed 20 years ago, where the repairs performed comprise both state of the art techniques and traditional techniques.

Idea Champion - Who at MnDOT/LRRB? : Richard D. Davis, PECS Director

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

This project fits MnDOT's "engagement, communications and education" focus area within the Statewide Multimodal Transportation Plan (SMTP), MnDOT's WIG 2.0 efforts to build customer trust, the State of Minnesota's Statewide Civic Engagement efforts, and the Federal Highway Administration's (FHWA) efforts to improve public engagement during the scoping phase of projects. The primary benefit is making MnDOT's public engagement efforts more accessible and understandable, which should lead to better and more engagement. By having better engagement, MnDOT can improve the ways in which it includes the public's perspective into its work.

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.

In light of the many issues surfacing in society today, implementing a 24/7 employee hotline/case management system, constructed by a third party vendor is necessary to meet our employee’s needs. Outlined below are the details pertaining to the reasons why this would be important.

 

This is important to meet current challenges of:

* Addressing complaints that do not surface because of the fear of retaliation. The primary benefit of a hotline is to address anonymous callers, especially in this environment where people like to remain anonymous, are leery about surfacing issues, and also have personal concerns about retaliation (even if the organization would not retaliate).

* To ensure we are held accountable to complainants regarding investigation timelines.

* Being transparent and timely as a government agency. Implementing a hotline would be timely, considering the fact
