A Continuous Flow-Through Water Quality Monitoring Systems for Highway Stormwater Management

By ahardingMay 7, 2021Leave a comment

Efficient and effective water-quality monitoring is key to understanding and setting water-quality objectives and meeting local, state, and federal stormwater regulations. Inaccurate representation of contaminants in urban runoff can lead…

Managing stormwater runoff in cold climate through improved training

By ahardingMay 7, 2021Leave a comment

As a major source of non-point source pollution, highway runoff has adverse effects on the adjacent aquatic resources if no measures are taken to remove the excessive contaminants accumulated from…

Cost-effective use of sustainable cementitious materials for stormwater management by DOTs

By ahardingMay 7, 2021Leave a comment

The proposed research provides an innovative multi-disciplinary approach to cost-effective management of storm water. DOTs needs effective tools to meet recently enacted federal (EPA) regulations for reducing the amount of…

Structural BMPs for managing bridge deck runoff in cold regions

By ahardingMay 7, 2021Leave a comment

This project will develop, install and field test the effectiveness of new structural BMPs specifically designed to manage runoff near one or two highway bridge decks, e.g., filters and biofiltration…

INCORPORATING VEHICLE EMISSION MODELS INTO THE HIGHWAY DESIGN PROCESS

By ahardingMay 7, 2021Leave a comment

The research regarding the reduction of the adverse environmental impact through highway design is still in its infancy. Furthermore, highway design manuals/guidebooks do not provide any information on environmentally-friendly designs.…

Passengership Optimization

By ahardingMay 7, 2021Leave a comment

In the USA’s 374 metropolitan areas of 50,000 population and above, there is a significant variation in the rate of road-based passengership (being a passenger in a car, van, or…

Development of Potential Performance Measures for Carsharing

By ahardingMay 7, 2021Leave a comment

Over the past decade, carsharing has evolved from an early-adopter stage to become a new mode of transportation in urban areas across the country. While significant work has been done…

Climate Change and NEPA – A State DOT Impact Assessment

By ahardingMay 7, 2021Leave a comment

State DOTs have measurably increased their participation in the climate change, transportation asset, and environmental planning linkage.  There is currently a national policy movement to address these linkages and how…

Transport-equation models for more cost-effective, accurate noise prediction in tunnels and urban canyons

By ahardingMay 7, 2021Leave a comment

This research project will apply a transport equation to predict noise distributions in long spaces/enclosures when multiple sources are present. Potential applications are transportation infrastructures such as tunnels, subway stations,…

Direct Liquid Applications: A Winter Maintenance Best Practice for Improved Road Salt Efficiency

By ahardingMay 7, 2021Leave a comment

As evidenced by the recent January 2013 EPA Webinar entitled “Road Salt Pollution Prevention” in which over 1000 people participated, the concern for road salt, or rock salt, and water…
