The purpose of this study is to provide a synthesis of re- cent experience with transportation system management (TSM) and parking management strategies, and enabling policy instruments such as trip reduction ordinances and developer agreements in suburban contexts. Based on literature reviews and focused interviews of key program officials at sites researchers, evaluators and private interest groups the project would develop a summary overview of important TSM and parking management approaches to address suburban congestion the observed ranges of trip reductions from implemented strategies and policies, and the determinants of effective-ness of these strategies and policies will be identified. Insights will be developed to guide suburban jurisdictions interested in pursuing such program to address their traffic problems. The focus of the study will be on the identification of factors that determine the success or failure of strategies as well as policy instruments. The aim will be to go well beyond the overview discussion of TSM and parking management strategies and derive lessons about implementation of policies to enhance the chances of wider adoption of these programs by local jurisdictions, private developers and employers.
