A thorough revision of a best-selling introduction to transportation engineering, which begins with the basic sciences, mathematics and engineering mechanics and gradually introduces new concepts concerning societal contact, geometric design, human factors, traffic engineering and simulation, transportation planning and evaluation. There is new coverage of transportation modes, urban transportation, flow interruptions, traffic impact and parking studies - including a discussion of traffic simulation and transportation planning software packages. Travel behaviour and modelling are also discussed. Concepts are developed and illustrated by carefully chosen examples.
