Abstract
This paper provides a general overview of freeway and interchange design worldwide. It is not an exhaustive treatise on the subject. To do so would involve a volume significantly greater than any of the geometric design policies in North America or Europe. Here, similarities and differences are explored and recommendations made for future research and improvement. Being compared here are the following freeway and interchange design issues: Design philosophy; Design elements; Interchange configurations and adaptability; and Operational guidelines for systems of interchanges.
