Do you know how the changes to AASHTO's "Green Book" will affect your highway and street design standards?

This publication serves as this nation's primary highway and street roadway geometric design reference.

Federal law provides that design standards for projects on the National Highway System (NHS) must be approved by the U.S.DOT in cooperation with the State highway departments, and the "Green Book" has been adopted for this purpose. Federal law also requires that projects other than highway projects on the NHS shall be designed, constructed, operated, and maintained in accordance with State laws, regulations, directives, safety standards, design standards, and construction standards. Since most state DOT guidance is derived from the "Green Book," much of the design guidance and standards used by local governments also evolves from this publication.

This program addresses the major changes in each chapter of the new book and discusses the use of updated design guidance and design flexibility throughout the document.

After viewing this program, participants will be better able to:

• Expand their knowledge of geometric design.
• Comprehend and apply the latest design policy guidance from AASHTO.
• Increase their ability to perform geometric design to current policies and discern how to apply design flexibility.
