A portable safety terminal based method for processing rail transit resources, the method comprising: in a degradation mode, performing interaction between a portable safety terminal and a wayside controller for controlling a train; providing a driver of the train with safety display of an environment where the train is located, and obtaining through the display a location of the train and information of a relationship between a front train and a rear train; and providing the driver with a means to apply for line resources, such that the driver can, according to the train environment, autonomously apply for the line resources, and release the resources for use by subsequent trains after driving the train to pass through a zone, wherein the interaction between a portable safety terminal and a wayside controller comprises interaction between safety display information and interaction between safety control commands, wherein the interaction between safety control commands specifically comprises: Step 1): after a status of wayside equipment in the environment where the train is located is obtained, applying to the wayside controller for track resources required for train operation and a control authority of the wayside equipment by an operating button on the portable safety terminal, and after the wayside controller confirms that the track resources are not occupied by other controllers or portable safety terminals, authorizing the portable safety terminal to control the track resources; Step 2): after the control authority of the wayside equipment to control the track resources is obtained, selecting, by the portable safety terminal, corresponding elements, icons, or menus on a display interface to control the corresponding wayside equipment to act; and Step 3): after the control on the wayside equipment is completed and the line resources are obtained, autonomously driving the train to pass through the control zone according to the display on the portable safety terminal; and after the train passes through the control zone, releasing the line resources via the operating button on the portable safety terminal, and returning the control authority of the wayside equipment for continued use by the subsequent trains or the wayside controller. Step 1): after a status of wayside equipment in the environment where the train is located is obtained, applying to the wayside controller for track resources required for train operation and a control authority of the wayside equipment by an operating button on the portable safety terminal, and after the wayside controller confirms that the track resources are not occupied by other controllers or portable safety terminals, authorizing the portable safety terminal to control the track resources; Step 2): after the control authority of the wayside equipment to control the track resources is obtained, selecting, by the portable safety terminal, corresponding elements, icons, or menus on a display interface to control the corresponding wayside equipment to act; and Step 3): after the control on the wayside equipment is completed and the line resources are obtained, autonomously driving the train to pass through the control zone according to the display on the portable safety terminal; and after the train passes through the control zone, releasing the line resources via the operating button on the portable safety terminal, and returning the control authority of the wayside equipment for continued use by the subsequent trains or the wayside controller.
