Roadway Geometric Design 1: Basic Concepts and Principles
This is the first of three courses in the TRANSPEED roadway geometric design series.
The other courses in this series are Roadway Geometric Design 2: Applications, Methods and Good Practice and Advanced Roadway Geometric Design.
Course Faculty: Bob Layton and Jan Botha
The design of the modern roadway system is a complex business that present the transportation engineer with many challenges. A practitioner must consider design controls and criteria which go beyond the basic application of standards. The cost of construction, the price of real estate, increasing traffic volumes, mixtures and size of vehicles, and environmental and ecological considerations are all part of the checklist and challenges the roadway designer faces on a daily basis.
This is the first of three courses in the TRANSPEED Geometric Design series that combine to provide a comprehensive education to the transportation engineer or planner on how deal with today’s challenges on the modern roadway system. In this course you will be provided an introduction to core concepts, principles, methods, practice and standards for roadway geometric design. Discussions will cover current policies and manuals, in particular the 1994 and 2001 American Association of State Highway and Transportation Officials (AASHTO) policy on geometric design and the WSDOT Design Manual.
