Abstract

This is a discussion of commonly held perceptions concerning transportation systems, followed by an evaluation of the extent to which they are true. The paper provides a logical development for arguments to refute those that are generally false. It is noted that most commonly held perceptions about transportation problems are myths. Transportation professionals and analysts need to understand these and be prepared to refute them. It is pointed out that it is possible to reduce traffic congestion and improve the flow of both limited access facilities and intersections by selective capacity additions, particularly interchanges. Channelizations, widenings, special lane restrictions, and other actions can substantially improve the overall flow in metropolitan regions.
