Summary Statement: Research is needed in fusing together public and private commodity flow and operational datasets describing the light and heavy truck shipments between supplies and buyers. The data fusion…
The purpose of this research is to evaluate dispersion models and understand their current limitations using data collected from tracer studies conducted at locations with complex real-world traffic flow patterns.…
Electric vehicle charging stations are becoming more commonplace in many states but vary as to type and format and usage-there is no consensus as to how they should be funded…
RESEARCH PROBLEM STATEMENT Interstate highway improvement projects that are deemed to have traffic noise impacts result in near-road barrier walls being constructed or expanded. Although the barriers are designed and…
The Congestion Management and Air Quality Improvement Program (CMAQ) has existed since 1991 providing benefits by reducing air pollution. This program has evolved over the years and will be entering…
Background: New vehicle technologies, publically sponsored programs, and public-private partnerships designed for various reasons but applicable to reduce vehicle-generated emissions have been emerging for a decade or more. These include…
Background: There are several types of models used in analyzing highway emission impacts to air quality for both regional analysis and project or hotspot analysis and for both for NEPA…
State DOTs would benefit from guidance that goes beyond the norm on how to conduct modeling for project-level air quality analyses and addresses which modeling inputs are the most cost-effective…
This project aims to model the environmental effect of a new form of car sharing system with free-floating vehicles. The free-floating vehicle system, unlike traditional car-sharing systems, is based on…
The objective of this project is to develop guidance on how to apply microscopic traffic simulation models to project level emissions analysis, focusing specifically on vehicle trajectory information. This project…
