This paper discusses the behavior of traffic jams with catastrophe theory. In highways, the determination of the specific condition of traffic jams-such as critical density and volumn of traffic flow, critical velocity of cars, etc(?)has been a subject in traffic engineering until now. In this paper, the critical value and the fundamantal equation of traffic jams are discussed and studied, and with an exsample the author defines that catastrophe theory is more close to the objective reality than smooth change...
