The Center has assisted state transportation agencies in developing numerous environmental stewardship practices, policies, and programs to

In 2003, AASHTO published the fi rst Taking the High Road report which chronicled the important contributions that state transportation agencies were making across the country. This second report, Above and Beyond, document

In this program, the agency has charged its regional maintenance organizations with fi nding immediate environmental stewardship actions that can be taken along roadsides in the

The vision advocates a “triple bottom line” approach t

Applying it to assess projects, programs, and policies sends a message that fi nancial, cost-benefi t, and economic considerations are not the sole drivers of transportation projects. Under this approach, economic, social, and environmental factor

46、lication is a violation of applicable law.1For almost a decade, transportation agencies have been advancing the concept of context sensitive solutions (CSS), in which transportation projects are planned, designed, and implemented to meet the needs of communities and the environment. CSS adds to the

47、traditional methods of project development by emphasizing collaborative and interdisciplinary decision making and by insisting that the contexts of a project are thoroughly understood before design decisions are made. The concept has evolved since 1998, when transportation agencies fi rst promoted “

48、context sensitive design” for projects at the infl uential Thinking Beyond the Pavement conference in Baltimore. Five pilot CSS programs were established in Connecticut, Kentucky, Maryland, Minnesota, and Utah. Today, this concept has expanded to additional states. Across the country, highway agenci

49、es are advancing a philosophy that involves all stakeholders in developing transportation “solutions” that go far beyond designing projects.Transportation leaders agree that every transportation project offers a unique opportunity to enhance safety, mobility, economy, and the natural environment. With these goals in mind, state and Federal highway agencies have established context se
