Traffic Flow Improvements: Quantifying the Influential Regions and Long-Term Benefits

项目名称：	Traffic Flow Improvements: Quantifying the Influential Regions and Long-Term Benefits
摘要：	The Congestion Mitigation and Air Quality (CMAQ) Improvement Program is a very important federal funding source that supports projects and programs for Massachusetts to improve air quality and reduce traffic congestion. It is anticipated that CMAQ will provide approximately $340 million to the Commonwealth for the 2018-2022 funding cycle. To leverage support from CMAQ for a project, a critical step is to obtain the review approval from the CMAQ Consultation Committee to assure that the project demonstrates significant air quality benefits. For projects in the category of traffic flow improvements, transportation agencies are often challenged by two important problems: (1) how to estimate the benefits to a secondary corridor due to the improvements of the primary corridor, and (2) how the gains of a project, including congestion relief (e.g., delay reduction) and reduction of air pollution (e.g., emission of NOx), will evolve over time. These problems are very important for the Massachusetts Department of Transportation (MassDOT) to understand the full-scale of gains from the traffic flow improvements and then to identify suitable projects and leverage resources from CMAQ for Massachusetts. The objective of this research is to conduct a synthesis study on the full-scale effects of traffic flow improvements in terms of the influential region and the changes of gains over time. The ultimate goal is to inform MassDOT�s Office of Transportation Planning�s evaluation of CMAQ projects and their demonstrated benefits to relieve congestion and improve air quality.
