This Green Book 8 Visioning Project resulted in an outline for the 8th Edition that was refined and adopted by the AASHTO Technical Committee on Geometric Design. Using this outline, the NCHRP Project 07-29 Project Team will develop the 8thedition of the Green Book and will integrate performance metrics that meet the full range of users and conside...
The adopted outline consists of four parts. Part I introduces performance-based design concepts and design decision-making. Part II provides performance metrics and an overview of applying a performance-based process framework. Part III covers geometric elements and configurations, using much of the detailed content from Green Book 7. Part IV is a ...
Green Book 8 will be a monumental shift to multimodal, performance-based context sensitive design. As such, it is being informed by a number of outside research activities. Here are just a few: 1. NCHRP Research Report 1022: Context Classification Application: A Guideassists transportation planners in identifying the appropriate context classificat...
The NCHRP 07-29 Project Team, led by Texas A&M Transportation Institute (TTI), is currently developing chapters for Green Book 8 with close coordination with the AASHTO Technical Committee on Geometric Design. We look forward to seeing how this monumental document incorporates the Green Book 8 Vision and many other research activities and outcomes ...
The AASHTO "Green Book" contains the current design research and practices for highway and street geometric design. It provides guidance to engineers and designers who strive to make unique design solutions that meet the needs of highway and street users on a project-by-project basis.
