The best-selling, newly updated Principles of Highway Engineering and Traffic Analysis, 5th Edition provides the depth of coverage necessary to solve the highway-related problems that are most likely to be encountered in engineering practice.
The focus on highway transportation is appropriate in light of the dominance of the highway mode in the U.S. and available employment opportunities. Instructors can be confident their students are learning the fundamentals needed to undertake upper-level transportation courses, enter transportation employment with a basic knowledge of highway and traffic engineering, and answer transportation-related questions on the Fundamentals of Civil Engineering and Professional Engineering exams.
