Highway Geometric Design Guide

Explore the Art and Science of Geometric DesignThe Geometric Design of Roads Handbook covers the design of the visible elements of the road-its horizontal and vertical alignments, the cross-section, intersections, and interchanges. Good practice allows the smooth and safe flow of traffic as well as easy maintenance. Geometric design is covered in d

TRB's National Cooperative Highway Research Program (NCHRP) Report 659: Guide for the Geometric Design of Driveways explores guidelines related to the geometric design of driveways. The report includes driveway-related terms and definitions, an examination of basic geometric controls, a summary of access spacing principles, and detailed discussions of various geometric design elements. Material related to and supporting the contents of NCHRP Report 659, including an extensive review of literature, has been published as NCHRP Web-Only Document 151: Geometric Design of Driveways.

This manual contains geometric design standards, guidelines and warrants for highway design. It is divided into the following chapters: Chapter A : Basic design principles; Chapter B : Alignment elements; Chapter C : Cross-section elements; Chapter D : At-grade intersection; Chapter E : Interchanges; Chapter F : Roadside facilities; Chapter G : 3R/4R geometric design guidelines; Chapter H : Local roads; Chapter I : Access management guidelines; Abbreviations; Symbols; Glossary; Index.
