A method uses a track-side obstacle identification arrangement and a vehicle-side obstacle identification arrangement in order to identify obstacles in a danger zone in front of a rail vehicle. In order to allow improved autonomous driving of the rail vehicle, it is provided that, as it approaches a relevant one of the obstacles, at least one reaction or response of the rail vehicle is derived depending on an evaluation signal of the track-side obstacle identification arrangement and an actual value of at least one variable which characterizes the effectiveness or performance of the vehicle-side obstacle identification arrangement. A system for identifying obstacles is also provided.

The present invention relates to a multi-layer coupling relationship-based train operation deviation propagation condition recognition method, where the method includes the following steps: (1) recognizing an effective train event time sequence, including an arrival event and a departure event of a train at each passing station; (2) uniformly extracting train activity data, including a stop activity, a section operation activity, a turn-back activity, and an arrival or departure interval activity; (3) constructing coupling relationship groups between a train event and a train activity and between train activities; and (4) performing statistics on changes of train operation deviation in each relationship group, and outputting a respective distribution function and a time-space distribution visualized result. Compared with the prior art, the present invention has the advantages of being practical, automatic recognition, feedback optimization, and the like.

An optimal driving profile is generated for vehicles provided with electric propulsion, by providing a sequence of consecutive time intervals until an arrival time and providing a plurality of accelerations that the vehicle can hypothetically take in each of the time intervals; by applying laws of uniformly accelerated motion for each of the accelerations and for each of the time intervals, hypothetical future points along the route are generated, starting from the current position and speed of the vehicle; for each of the time intervals, before analysing the subsequent time interval, it is checked whether the generated points meet all the predefined constraints; if the check has a negative outcome, the point being checked is eliminated from the plausible hypotheses; driving profiles are obtained, each defined by a respective sequence of remaining points; from among said driving profiles, the one requiring a lowest overall energy to be executed is selected.

The method comprises, for a given route between a starting point and a destination, and for an arrival at the destination at a given desired time: a preliminary step of determining and recording a plurality of vehicle mission profiles, at least a first instant during the journey, a step of determining an instantaneous position of the vehicle at this first instant and a desired time remaining to reach the destination, a step of identifying, among the mission profiles, the mission profile(s) whose curves are closest to the desired time remaining at the instantaneous position of the vehicle, and a step of determining new driving parameters to follow a new mission profile, the new mission profile being determined on the basis of the determined mission profiles.

A system for managing the transportation of crude oil by rail includes a user terminal having a display screen and a processing system coupled to the user terminal through a communications link. The processing system is operable to generate a user interface on the display screen of the user terminal receiving input information from a user, including information indicating a loading facility for loading a selected set of railcars and an unloading facility for unloading the selected set of railcars. The processing system is further operable to forecast an arrival time for the set of cars at the loading facility and an arrival time for the set of cars at the unloading facility and display the forecasted arrival times at the loading and unloading facilities on the display screen of the user terminal.

A vehicle control system includes one or more processors configured to assign plural vehicles to different groups in one or more vehicle systems for travel along one or more routes. The one or more processors also are configured to determine trip plans for the different groups. The trip plans designate different operational settings of the vehicles in the different groups at different locations along one or more routes during movement of the one or more vehicle systems along the one or more routes. The one or more processors also are configured to modify one or more of the groups to which the vehicles are assigned or the operational settings for the vehicles in one or more of the vehicle systems based on a movement parameter of one or more of the vehicle systems. The trip plans for the different groups of the vehicles are interdependent upon each other.
