With the increasing of passenger demand and train frequencies, small disturbances often occur in the daily operation of metro lines. Automatic train regulation algorithms are designed for the automatic train supervision (ATS) systems to cope with those small variations. In some practical train control systems, the running times between two consective stations cannot adjust in a continuous time interval, but can only choose several discrete running times. These running times are called operation levels in the ATS systems and correspond to several precalculated speed profiles in the automatic train operation (ATO) systems. An operation level based train regulation model is proposed in this paper to enhance the performance of ATS automatic regulations, which achieves a good trade-off between train delays, energy consumption, and headway variations. The data of the Beijing Yizhuang line is used to demonstrate the effectiveness of the proposed model and solution approach.
