Abstract: The existing running time control methods of signal system need to be replanned when applied to different lines, slow response to time error and have large error when temporary speed limit exists. Based on the constant impact rate model, this paper studies the time prediction method under the section command speed set, calculates the remaining running time of the train, and adjusts the section command speed set in real time according to the real remaining running time, so as to control the train running efficiently and punctually. The field test is carried out on a subway line. The result shows that the error between the actual running time and the set time is less than 3.5% based on the constant impact rate model calculation method, which can make the global and reasonable planning of the train running speed in real time and online, and ensure the train running efficiency and comfort requirements.
