New Project: Improving and Developing Pavement Design Inputs and Performance Functions for Cold Recycled Pavement Layers

Local agencies in Minnesota use cold recycling technologies for flexible pavement rehabilitation because of their economic and environmental benefits. The three main methods are cold in-place recycling (CIR), cold central plant recycling (CCPR), and stabilized full-depth reclamation (SFDR).

New Project: Development of a System to Report School Bus Stop Arm Violations

When a motorist ignores an extended school bus stop arm, it creates a direct and serious risk to children boarding and exiting a school bus. Capturing information about such incidents is a critical step in better understanding why they occur and how they can be prevented.

New Project: Evaluation of Static and Dynamic No Right Turn on Red Signs at Traffic Signals

Making signalized intersections safer for pedestrians can be achieved by reducing points of conflict between pedestrians and vehicles. One source of conflict occurs when a vehicle makes a right turn on red (RTOR) onto a street in which pedestrians are crossing. During this turn, the driver must cross the path of pedestrians while at the same time searching for gaps in conflicting vehicle flow.

New Project: Develop Element Level Bridge Performance Measures and Targets

Currently, federal bridge performance measures in the United States and measures most commonly used by state transportation agencies for bridge management are based on National Bridge Inventory (NBI) General Condition Ratings that reflect bridge component conditions (deck, superstructure and substructure).

MnDOT also collects bridge element data that provides a more granular, objective and quantitative assessment of condition, and would like to have performance measures and targets based on the bridge element data that guides a data-driven methodology to select cost-effective treatments.

New Project: Development of Erosion Control Product Longevity Test Methodology

MnDOT has approved products for blanket and hydromulches. There are many versions of each type of temporary erosion prevention materials, that vary in thickness, composition, and cost.

The two most common stabilization methods to control erosion and establish vegetation used by MnDOT are Hydraulic Erosion Control Products (HECP) and Rolled Erosion Prevention Products (REPP). Specifying the best fitting product for the situation keeps MnDOT in compliance with stormwater permits and is more cost effective.

New Project: Complete Streets Speed Impacts

Minnesota Statutes §174.75 requires the MnDOT to follow a complete streets approach in all phases of planning, project development, operation, and maintenance activities. The purpose of the MnDOT complete streets policy “is to address the safety and accessibility needs of users of all ages and abilities. MnDOT assesses user needs at several stages of planning, project scoping and designing, construction, operation, and maintenance.”

New Project: Development of Process to Lower Global Warming Potential of Construction Materials

Advances in science of life cycle assessment (LCA) have set the stage to develop methods that meet global warming potential (GWP) reduction targets for construction materials, specifically, using instruments such as Environmental Product Declarations (EPD).

New Project: Assessing a New Tool for Early Detection of Endangered Turtles on Proposed Transportation Projects

As turtle populations decline worldwide, increased protections (e.g. United States Endangered Species Act) yield increased regulatory burdens. As a consequence, monitoring of imperiled turtle species is imperative to understand both their extant distributions, but also to ensure regulatory compliance.

However, conventional methods for surveying turtles are frequently costly, time consuming, require taxonomic expertise, and unlikely to yield detections without repeated visits. And these burdens are exacerbated when sampling rare, threatened, or endangered (RTE) species. In these instances, innovative technological advances may overcome these limitations, ultimately streamlining monitoring.

New Project: Assessing Methods to Mitigate Cognitive and Physical Declines That Influence Driving Performance of Older Drivers

Supporting older drivers to safely age in place as they experience age-related declines is important as many Minnesota drivers are reaching retirement age.  Minnesotans, 65 years and older, are expected to represent 20% of the state population by 2025, with an overall increase of 122% from 2010-2040. While older drivers are generally safe drivers, those aged 75-85 face the highest risks from injury.
