COMPUTER IMPLEMENTED METHOD FOR DETERMINING RAILWAY VEHICLE MOVEMENT PROFILE TYPE OF A RAILWAY VEHICLE MOVEMENT PROFILE AND CONTROLLER OF A TRACK CIRCUIT SYSTEM
A computer implemented method is for determining railway vehicle movement profile type of a railway vehicle movement profile. The railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time. The method includes obtaining a railway vehicle movement profile, normalizing the railway vehicle movement profile, extracting one or more features from the normalized railway vehicle movement profile, determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process, and assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid
Method for communicating information between an on-board control unit and a public transport network
A method is provided for communicating at least one item of information between a first control unit on-board a first vehicle and a public transport network. The information is sent as a command from the first control unit to a first communication unit on board the first vehicle. The first communication unit establishes a transmission link outside the vehicle with a second communication unit connected to a module for executing the command. The second communication unit and the execution module are located on the ground. The first control unit controls the execution module on the ground in a governed slave mode for the command by a master mode of the first control unit.

Safety method and safety system for a railway network
A safety method for a railway network that is divided into section segments by way of section elements and which can be traveled by vehicles in accordance with data from a section atlas. The vehicles request steps for allocation as a track element from selected section elements. Each of the selected section elements autonomously allocates itself as a track element under specified conditions for each requesting vehicle. In order to be able to inform the vehicle or the vehicle operators thereof about changed section characteristics better and more quickly, for the section elements, the vehicles store manually entered and/or manually released dynamic driving operation data as a dynamic component of the section atlas in parts related to the section elements.
