Asphalt Film Thickness vs a chip seal at 1 year ‐ B/C analysis

A better understanding and comparison of the benefits of higher Asphalt Film Thickness (AFT) and chip seal is needed to inform pavement maintenance techniques and to optimize cost effectiveness. The research should include a benefit-cost analysis at 1 year of service life and explore the benefits of implementing both treatments at the same time. State Aid Pre-Screening Meeting input: Benefits of higher AFT... more »

Cost life cycle of local roads

It is often challenging for the public and policy makers to understand the maintenance cost of local streets over the service life of a roadway facility. Education/Training tools are needed to help local agency staff communicate these costs and inform budgets over the service life of a roadway facility. State Aid Pre-Screening Meeting Input: Education to help city staff to understand how a local street will cost over... more »

Mill and overlay ‐ BMP

There are a variety of mill and overlay methods and a variety of crack sealing methods used for Minnesota roadways. Understanding how well these methods peform in terms of pavement life and the minimization of reflective cracking would be beneficial to roadway agencies. Several alternative methods have been used in recent years and a review of the effectiveness of current best practices would help inform cities and... more »

Effectiveness of fog seal on chip sealed low volume roads

Local units of government have experience using a fog seal over chip sealed pavement. This practice is often used on low volume roads with residential driveways. Residents often complain about the impact of the fog seal on driveways. Research is needed to understand the effectiveness of fog seal over chip sealed pavements and results interpreted in outreach materials to help educate stakeholders on the benefits of... more »

Evaluate Effectiveness of Storm Ponds for Water Quality

Recent studies suggest storm water ponds may not offer the best long term treatment for water quality. Modeling of pond performance may not be accurate. Research is need to explore best management practices for stormwater treatment. State Aid Pre-screening meeting idea input: Are storm ponds still the best management practice for water quality application? Recent studies suggest storm ponds may not offer the best... more »

Developing Micromobility Management Tools through User Fees

Micromobility (electric scooters, electric bikes, etc.) services quite literally arrived overnight on Minnesota streets in 2018. While, these services offer many benefits to the transportation system, they also bring a number of challenges that need to be examined. Notable issues include addressing the operational needs, unique infrastructure demands, and the public's concern over where these vehicles are stored when... more »

Impacts of Airport Zoning on Land and Property 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 »

Vegetation management practices to enhance roadside pollinator habitat

Pollinators such as native bees, including the federally-endangered rusty-patch bumble bee (Bombus affinis), and Monarch butterflies are at risk due to the loss of native habitats from increasing development, intensive agricultural practices, and greater use of pesticides. Roadside habitats, in particular, have grown in importance as they can provide habitat and act as migratory corridors. The objective of this project... 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 at... more »

Best Practices for Winter Maintenance for Pedestrian Safety and Accessibility

Pedestrian fatalities on US roadways have been increasing in recent years. According to the National Highway Traffic Safety Administration, there were nearly 6,000 pedestrian deaths in traffic crashes in 2016, representing 16% of all traffic fatalities (NHTSA. Traffic Safety Facts. 2016 Data). This was an increase from 4,700 and 11% in 2007. In Minnesota, while other crash types of traffic fatalities have declined, deaths... more »

Evaluating the Impacts of Construction Projects on Transit Service Performance

Corridors such as I-35W and I-494 in the Twin Cities region have been undergoing major construction projects. During project scoping, preliminary plan development stage and construction stage, the Transportation Management Plan (TMP) offers mitigation strategies to minimize work zone impact. Research is needed on how transit operations is impacted by these construction projects and develop possible transit mitigation... more »

Electronic NPDES Inspection and Performance Measurement Tools

The NPDES permit requires the owner and operator to inspect the entire site each week and after any rain fall greater than 0.5 inches in a 24 hour period. While the inspection report has a permit defined minimum criteria, the intent is a quality control and assurance tool for the owner/operator to correct deficiencies in a timely manner. This document creates something similar to a weekly punch list for scheduling the... more »

Stormwater Inlet Protection Device Determination of Performance

The NPDES permit requires inlet protection due to stormwater and construction operations. How to implement effective inlet protection remains a mystery if the intent is to 'protect' storm egress inlets while providing a flood prevention bypass and for all types of construction activities. Significant time and money are currently being expended in the purchase and installation of sediment and pollutant control inlets devices... more »
