Abstract

Train braking accuracy and safe protection distance are the two main technical indexes in the system design of an automatic train protection system. They are closely related to safety and efficiency of train operation. When a train is actuated automatically to be braked by automatic train protection (ATP) system, no matter it is service braking or emergency braking, a proper safe protection distance must be considered because of limited braking accuracy. If the safe protection distance is too long, it will reduce train operation efficiency and disturb normal train operation controlled by drivers. If it is too short, train operation can not be ensured to be safe. Optimal safety protection distance is one of the
