System includes a control system used to control operation of a vehicle system as the vehicle system moves along a route. The vehicle system includes a plurality of system vehicles in which adjacent system vehicles are operatively coupled such that the adjacent system vehicles are permitted to move relative to one another. The control system includes one or more processors that are configured to (a) receive operational settings of the vehicle system and (b) input the operational settings into a system model of the vehicle system to determine an observed metric of the vehicle system. The one or more processors are also configured to (c) compare the observed metric to a reference metric and (d) modify the operational settings of the vehicle system based on differences between the observed and the reference metrics.

The present invention relates to a full-day in each train operation diagram generation method based on a time division scheme and an activity-event relationship, the method including: S1: configuring operation scheme basic parameters; S2: constructing a quantitative relationship between a travel time and a driving interval for different routing ratios and calculating, within a given turn-back time range, an actual turn-back time of each turn-back station that can achieve a routing ratio requirement; S3: generating an arrival event time and a departure event time of a train in each time period at a station platform in accordance with routing division, direction division, and proportion division, correcting a start time and a stop time of each routing in accordance with time period division, and performing transition between the time periods; and S4: connecting a train section operation activity and a stop activity according to the full-time train arrival and departure event times obtained by executing step S3 for a plurality of times, matching an underbody turn-back activity with ex-warehousing and warehousing activities, and correcting arrival and departure times related to a track occupation conflict, thus obtaining a full-day train operation diagram. Compared with the prior art, the present invention has the advantages of a standardized routing ratio, automatic high-low peak connection transition, and the like.

To improve throughput rates of packets transmitting positive train control (PTC) messages in an asynchronous wireless network that supports controlling movement of trains, data rates are adjusted based one or more conditions of the link. Modulation and coding schemes with less overhead can be employed to increase the data rate at which information is transferred when an estimated link quality or conditions are relatively good. Conversely, when the estimated link quality is relatively poor, more robust modulation and coding schemes for transmissions can be used to maintain link performance but at the cost of reduced data rates. Optionally, if the estimated link quality is higher than required to achieve a predefined maximum transmit rate at a given default power rate, transmit power can be reduced to that necessary for transmit at the predefined maximum transmit rate.

A solution for detecting and alerting to intrusions or obstacles in an area. One or more sensing devices can be used in combination with computer processing capabilities to monitor an area for intrusions or obstacles. An illustrative area is part of a railyard or railroad track, which can be monitored for intrusions by foot, vehicle, or even by inanimate objects such as falling rocks from a track cut. The sensing, computing, and/or alerting systems can be redundant to ensure operation at all times.

A system and method include a control unit configured to detect a presence of a vehicle within a route area based on sensor signals output by an observer device that monitors the route area. The control unit is configured to determine a distance of the vehicle from the observer device and to determine a vehicle location of the vehicle based on the distance and a predetermined location of the observer device. The system and method include a communication device configured to communicate the vehicle location to at least one of the vehicle or a remote control device that is off-board the vehicle prior to the vehicle starting to move along a route occupied by the vehicle.
