| 摘要： | Under the Congestion Mitigation and Air Quality (CMAQ) Program, the Federal Highway Administration (FHWA) distributes funds to states to assist in projects and programs that help reduce vehicle-related emissions in areas with nonattainment or maintenance status. Many types of projects can be considered for CMAQ funding including traffic signal synchronization, ride-sharing programs, and diesel retrofit projects. To obtain CMAQ funds, states must submit an analysis describing the air quality improvement benefits that the project or program will achieve. Analyses submitted in the past to justify a particular project or program have varied widely from a simple qualitative description of the estimated emission reduction benefit to more complex project-specific quantitative analyses. As the time and cost for conducting such analyses can be significant, state DOTs and other project sponsors can benefit from simplified procedures, including the use of lookup tables for typical project types that would significantly reduce the time and cost for analyses by state DOTs while also serving to improve the consistency and accuracy of the estimated emission reductions for FHWA. This research developed a spreadsheet-based Simplified Toolkit that can be used to calculate emissions reductions for 16 project types, based on minimized and simplified inputs. The NCHRP 25-25 Task 108 Simplified Toolkit is independent of the FHWA CMAQ Emissions Calculator Toolkit (available HERE), but is designed to build upon that resource by providing state DOTs, metropolitan planning organizations (MPOs), and other project sponsors with additional tools to efficiently calculate emissions reductions in accordance with federal requirements. |
