摘要： A method validates an obstacle identification system. In order to be able to demonstrate that obstacles are identified by an obstacle identification system at least as reliably as by a driver, it is provided that, in order to form driving scenarios, stochastic combinations of prespecified distributions of submodules are provided. The provided combinations are subjected first, for carrying out a simulation study, to simulation by a simulator and second to automatic processing by an obstacle identification algorithm of the obstacle identification system, and a result of a simulation study, which is carried out by the simulator, and a result of the automatic processing are automatically tested for agreement.

摘要： A method is provided for operating a railway network having a number of trains, the method comprises operating a scheduling machine that is in communication with the railway network over a data communication system, to receive time separated state data defining states of the railway network at respective times. The scheduling machine accesses a model of the railway network that is stored in an electronic data source. The model defines locations in the railway network that allows for passing of trains and paths for journeys of each of the trains. The method includes operating the scheduling machine to apply the state data to the model to determine, at each of the respective times, controls associated with each trains' path for each of the trains. The scheduling machine is operated to determine the controls by optimizing a objective function for the trains, such as minimizing total travel time of the trains, taking into account the locations in the network, positions of the trains and paths of each of the trains. The controls are transmitted, via the data communication system, to control movement of the trains, for example by operation of railway network switches (points) and signal lights, through the railway network based on the controls.

摘要： The Station Time Grade Time Stop Time and Relay Time Testing Device (SGSRTD) is a portable device that allows one to test whether various railroad-based components and elements, circuits, controls, relays, and systems are operating optimally or pursuant to manufacturers' specifications. SGSRTD comprises a multitude of components, including a power switch, electronic programmable timers, connectors, shunt switch, DC relays, AC relay, and leads. When coupled with a limit switch, an SGSRTD system is formed.

摘要： A system and method for simulating positive train control (PTC) systems in a local and controlled environment using software and hardware. The system can simulate various functionalities of the PTC system in the environment using software and hardware components. The system can instruct the software of a train management computer (TMC) to control electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing locomotive engineers and conductors to experience the PTC system for optimum training.

摘要： Systems and methods for train consist management are provided. In an aspect, a method includes, but is not limited to, designing a train consist; analyzing the train consist with a physics-based dynamic force model to determine whether the train consist would experience at least one of in-train force imbalances or lateral force imbalances indicative of at least one of a component malfunction or a derailment scenario for a proposed train route; and validating the train consist when it is determined that the train consist would not experience in-train force imbalances indicative of at least one of a component malfunction or a derailment scenario for the proposed train route.

摘要： A test support method includes a step of obtaining a pre-change image and a post-change image to be displayed on a monitoring and control system, a step of extracting, from the post-change image, multiple symbols that have changed from corresponding symbols in the pre-change image, a step of adding order information to the multiple symbols extracted, and a step of outputting a test image in which the order information is added to the multiple symbols.

摘要： A plurality of simulations executed by a plurality of simulators, respectively, coupled to one another to perform communication are executed efficiently and fast as a whole when executed in cooperation. An information processing system stores execution order information that is information indicating execution orders of the plurality of simulations. Each of the simulators generates output data by executing a corresponding one of the simulations based on input data that is data input at execution start, and execution control of the other simulations is performed when the simulation has reached a check point at a time point halfway through execution of the simulation. The check point is set based on, for example, a viewpoint of time or a viewpoint of situation of the simulation.

摘要： A train simulator test set is disclosed that can be operably coupled to a railroad track to measure the resting impedance of that track circuit and simulate a train by varying the railroad track inductance over a set period of time. The test set can select the speed, direction, and number of trains to simulate. By applying a variable inductance on the railroad tracks, the test set can simulate a train moving at variable speeds toward and away from the island. The test set can apply inductances to the railroad tracks to simulate two or more trains moving in each direction of the tracks at the same time, along with multiple looks and routes. The train simulator test set can include simulation software to vary the parameters of the train simulation and couple a variable inductance on the railroad tracks.
