" Problems with these statements A stochastic description is only useful if one de nes the random variables, Queueing is the study of traffic behavior near a certain section where demand exceeds available capacity. their respective areas. Includes many worked examples and homework problems. This chapter presents the relevant fundamentals of traffic flow theory. A BRIEF HISTORY OF TRAFFIC FLOW THEORY Historically, traffic engineering got its roots as a rather practical discipline, entailing most of the time a common sense of its practitioners to solve particular traffic prob-lems.
