The Evaluation And Study About Passenger CAR Equality

In this paper, the PCE principle, method and technical achievement of traffic engineering in domestic and overseas from 1940 to 1993 are analyzed ,compared and evaluated .Moreover ,the use condition and limitation of the studying achievement are elaborated .Based on it ,in view of the complexity of the vehicle kinds and mixed traffic in domestic highway traffic ,the physics method on influence space of vehicle is put forward according to the achievement of studying the road capacity and the mass traffic observation data of 177 section of highway . In addition, the vehicle influence space, principle, character ,conception and the mathematics model are discussed . By analyzed a number of experiment, the criterion to define type of vehicles, the side and vertical direction feature to road place occupied by vehicles which are traveling as well as the fixed quantity to describe the relationship to each other are determined. At last, the PCE of different traveling conditions are also put forward.
