The Evaluate Of Transportation Model And The Study Of Equilibrium Model

This paper introduces the background of the transportation programming first, analyzing the development condition of domestic and international transportation.Discusses the classical equilibrium model intensively and systematically in the chapter two, Because the transportation distribution model is the core of four-stage pattern, this paper introduces and analyzes the urban transportation network, traffic assignment models, standard user-equilibrium model .Then through studying the DanDong City road transportation planning, the paper fixes the parameters of many mathematics models.Changes the link travel function of Frank-Wolfe algorithm, through taking the factors of delay in the intersections into account, the paper presents the method of computing the travel cost in the intersections under the signal control.At the same time, the turn plenty function takes the different turn flow and the different intersections into account.
