A Performance-Based Highway Geometric Design Process

This report presents a new process for highway geometric design that is more aligned with current expectations of transportation agencies and their communities and makes full use of the tools available to them. The report reviews the evolution of highway design, presents several key principles for today’s design challenges, recommends a new highway geometric design process, and demonstrates the value of the process through six illustrative case studies. The new process focuses on the transportation performance of the design rather than the selection of values from tables of dimensions applied across the range of facility types. The report could be used for senior staff in transportation agencies as they consider changes to their design processes and by AASHTO in the development of future editions of A Policy on Geometric Design of Highways and Streets (the Green Book).
