In 1971, the U.S. Environmental Protection Agency (EPA) first set National Ambient Air Quality Standards (NAAQS) for CO. EPA set an 8-hour primary NAAQS at 9 parts per million (ppm) and a 1hour primary NAAQS at 35 ppm (see table below). All CO areas are currently meeting the NAAQS and have approved maintenance plans.
The primary objective of this project is to develop multiple simulation testbeds/transportation models to evaluate the impacts of Dynamic Mobility Application (DMA) connected vehicle applications and Active Transportation and Dynamic management (ATDM) strategies. While the project aims at evaluating both DMA applications and ATDM strategies, the pr
