A method for data transmission inside a rail-bound traffic system has of a plurality of field elements, in which the data transmission takes place via a flexible wireless transmission path between a sender field element and a control unit along available field elements. A data transmission system is for application of the method and a rail-bound traffic system having such a data transmission system. Furthermore, there is use of communication units on field elements of a rail-bound traffic system to form the data transmission system.

Disclosed is a method for guiding passengers of public transport, in particular of trams or trains respectively, at stations or in station areas and/or inside the transportation unit. The passengers embark and disembark in the embark-/disembark area via at least two doors, and the embark-/disembark area extends to the length of the vehicle. The method includes: generating a prediction of the occupancy level of the vehicle with regard to the resulting situation in the vehicle after disembarking at each stop; distributing of the passengers which are moving to the entry area and/or waiting in the entry area ready for embarking corresponding to the prediction to the area of the doors for an approximately uniform distribution of the passengers inside the vehicle; and if applicable, distribution of the passengers inside the vehicle under consideration of the predicted, preferably section-wise occupancy level and of the passengers actually ready for embarking.

According to one embodiment, an abnormality diagnosis apparatus includes processing circuitry. The processing circuitry estimates a reduction amount of a regeneration amount of a diagnosed vehicle that is a railway vehicle, based on vehicle data of the diagnosed vehicle and vehicle data of a peripheral vehicle different from the diagnosed vehicle. The processing circuitry corrects the regeneration amount of the diagnosed vehicle, based on the estimated reduction amount. The processing circuitry diagnoses abnormality of a regenerative brake of the diagnosed vehicle, based on the corrected regeneration amount.

In an example, the autonomous vehicle (“AV”) can be configured among the other vehicles and railway to communicate with a rider on a peer to peer basis to pick up the rider on demand from a location on a track, like a railway, tram or other track, rather than the rider being held hostage to a fixed railway schedule. The rider can have an application on his/her cell phone, which tracks each of the AVs, and contact them using the application on the cell phone. In an example, the AV is configured for both on-track and off track operation with different operating parameters for on-track and off track, including speed, degree of autonomy, sensors used etc.

A system, method, and computer program product for determining ancillary subdivision/districts may include obtaining route data associated with one or more vehicle network operators operating one or more subdivisions/districts over which the vehicle group may travel, determining an ancillary subdivision/district of the one or more subdivisions/districts that are not included in the route data by any of the one or more vehicle network operators, receiving route data for the vehicle network operator associated with the ancillary subdivision/district, and communicating with one or more wayside interface units in the ancillary subdivision/district based on the route data.

A system for vehicle management includes a control signal interface subsystem and a vehicle-mounted subsystem. Each of these subsystems includes an ultra-wideband (UWB) communications component. The subsystems communicate with each other through the UWB components. The vehicle mounted subsystem interfaces with a braking system of the vehicle. The vehicle mounted subsystem determines the distance between it and the control signal interface subsystem based on the time-of-flight of at least one communication between the subsystems. The vehicle-mounted subsystem can cause the braking system of the vehicle to activate if the distance between the vehicle-mounted subsystem and the control signal interface subsystem is less than a threshold.

A system configured to be disposed onboard a vehicle includes a communication unit and a processing unit. The communication unit is configured to obtain first trip information including first location-based operational information. The first trip information includes commands for a positive train control (PTC) system. The communication unit is also configured to obtain second trip information including second location-based operational information. The second trip information includes trip profile information for performing a mission by the vehicle. The processing unit is configured to obtain the first trip information and the second trip information from the communication unit, and to determine combined trip information using the first trip information and the second trip information. The processing unit is also configured to develop control information using the combined trip information.

A computer-implemented method is provided that includes obtaining a first secret and a first public key, and obtaining a second secret a second public key. The method may also include authenticating the first public key of the first vehicle based on a first private key associated with the first vehicle, and authenticating the second public key of the second vehicle based on a second private key associated with the second vehicle. The method may also include preventing a man-in-the-middle attack, by securing at least one of a first vehicle-to-central office communication, a central office-to-first vehicle communication, or a first vehicle-to-second vehicle, wherein the first vehicle-to-central office communication and the central office-to-first vehicle communication are authenticated based on a determined private key associated with a respective first vehicle on-board computer, and sending a message, with the central office server, to a vehicle associated with a conditional movement authority.
