Study on Model and Method of Train Working Diagram of Urban Rail Transit

This paper first analyzes the characteristics on train working diagram of urban rail transit,on the basis of describing property on rail line of urban rail transit,this paper puts forward theory of two stations drawing and three stations drawing which taking the setting of vehicle depots as the core of the subject designs sequence and contrary advance calculating methods to calculate the train arrival and departure time at mediate station,and builds mathematic model on the train working diagram of urban rail transit taking same interval time of train traveling as the target function.At last,these theories above are proved with computer simulation through the data of No.13 rail line of Beijing urban rail transit.
