Note: This research idea was short-listed at the 2015 TRB meeting of the Project-Level Subcommittee of the Transportation and Air Quality Committee (ADC20). The broader research problem to be addressed…
The NCHRP 25-25 Task 78 study (2015) successfully developed templates for programmatic agreement (PA) and associated technical documentation that are designed to be implemented by state DOTs to streamline project-level…
Most recently, NCHRP 25-25 Task 78, developed templates for a PA for CO hot-spot analysis and identified needed research areas to develop PAs for PM hot spot analyses and MSAT…
In 2007, the National Research Council (NRC) issued the landmark report “Models in Environmental Regulatory Decision Making” (http://www.nap.edu/catalog/11972/models-in-environmental-regulatory-decision-making). It assessed EPA’s use of computer models in developing regulations and recommended…
There are many air pollution emission components associated with motor vehicles, which historically have been subjected to stricter and stricter environmental controls, including running exhaust, crankcase running exhaust, cold start,…
The use of mobile source emissions models is inescapable for many regulatory, planning, and research applications in the air quality and transportation field. Although the U.S. Environmental Protection Agency’s MOVES…
The purpose of this research is to evaluate modeling techniques and ambient measurements to comprehensively understand and explain vehicle emissions contributions to local air quality. The research will consist of…
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 designation and classification of areas as nonattainment areas has significant impact on that area. It requires developing both policy and technical approaches to bring the area back into attainment.…
This research will provide information on the sensitivity of ambient air quality to project-level traffic and other key inputs in the traffic, emission and dispersion modeling chain including meteorological inputs.…
