Urban rail transit train operation diagram construction method based on operation levels

The invention discloses an urban rail transit train operation diagram construction method based on operation levels. The method comprises the steps that firstly, a train traction energy consumption calculation model and an artificial neural network model are established; the whole line operation time is divided into different operation levels according to the compression degree of the turn-back operation time, and the shortest interval operation time of each operation level is calculated to obtain the whole line redundancy time under each operation level; then based on a train traction energyconsumption calculation model and an artificial neural network model, redundant time distribution is carried out under each operation level; and finally, the redundant time distribution result is inputted into an ATS system, and a new train running chart is compliled. According to the method, the purposes of comprehensive energy conservation and consumption reduction and intelligent operation optimization management of th
