摘要

In recent years, Context Sensitive Solutions (CSS) has been promoted by both AASHTO andFHWA as a best practice for project development. CSS provides a systematic andcomprehensive approach to project development from inception and planning throughoperations and maintenance. Recently, the economic constraints that several state DOTs havefaced have created a new emphasis on financial issues as they relate to project development.Practical Design and Practical Solutions are a process that emphasizes design solutions thataims to achieve the maximum rate of return on the individual project and maximize systemreturns. As a result the concepts of Practical Design and Practical Solutions have seeminglyclashed with CSS. On the contrary, these concepts address and emphasize the system-wideoptimization which was not addressed by CSS. Moreover, they improve CSS applications andprinciples by further refining them and they potentially could add the need to consider system14wide improvements. The main conclusion from the work presented here is that a systematic,principle-driven, benefit-justified project development process is necessary to deliver theappropriate project. This paper presents the concepts and issues for each and compares theirapproaches aiming to initiate a dialogue on understanding these approaches and improving theproject development process so that it is more comprehensively performance oriented.
