The invention discloses an urban rail transit ATS energy-saving time table compilation method. By analyzing energy-saving operation modes of a plurality of trains, decomposing operation stages and approximately calculating the available energy-saving operation overlapping time, train operation energy consumption is provided for energy consumption calculation; and in addition, the genetic algorithm is introduced, the aim of minimizing the total energy consumption is transformed into the aim of optimizing the optimal arriving time and departure time of the multiple trains, and the multiple trains are subjected to subsection calculation in an off-line calculation mode. An ATS energy-saving time table generated through the method can achieve the purpose of reducing the total operation energy consumption of the multiple trains.
