摘要:
A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system. Alternative routes through congested areas are automatically selected using congestion prediction metrics.

A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system. Deadlock is avoided by controlling the entry of trains into congested areas, and may be automatically implemented by the use of traffic flow analysis algorithms.
摘要:
A system includes a scheduling module and a resolution module. The scheduling module determines plural initial schedules for plural different vehicles to concurrently travel in a transportation network. The initial schedules include locations and times for the vehicles to travel. The resolution module modifies at least one of the initial schedules to one or more modified schedules based on an anomaly in at least one of the vehicles or the routes that prevents one or more of the vehicles from traveling in the transportation network according to the initial schedules. The scheduling module communicates the modified schedules to the vehicles so that energy management systems disposed on the vehicles modify travel of the vehicles according to the modified schedules.

摘要:
A method includes forming a first schedule for a first vehicle to travel in a transportation network. The first schedule includes a first arrival time of the first vehicle at a scheduled location. The method also includes receiving a first trip plan for the first vehicle from an energy management system. The first trip plan is based on the first schedule and designates at least one of tractive efforts or braking efforts to be provided by the first vehicle to reduce at least one of an amount of energy consumed by the first vehicle or an amount of emissions generated by the first vehicle when the first vehicle travels through the transportation network to the scheduled location. The method further includes determining whether to modify the first schedule to avoid interfering with movement of one or more other vehicles by examining the trip plan for the first vehicle.

A method of planning the movement of plural trains over a train network utilizing route protection for the route immediately ahead of a train to avoid undesirable changes to the planned route of the train.
摘要:
A method includes determining candidate schedules for plural vehicles traveling in a transportation network comprising and identifying a gridlock area in the transportation network by simulating travel of the vehicles according to the candidate schedules. The gridlock area includes a geographic subset of the transportation network during a time window having at least a predetermined number of failed candidate schedules that result in a decrease of a throughput parameter. The throughput parameter represents flow of travel of the vehicles in the transportation network. The method also includes determining an alternate schedule that differs from the candidate schedule for one or more of the plural vehicles (e.g., a first vehicle of the plural vehicles) that is traveling through the gridlock area. The alternate schedule dictates travel of the one or more of the plural vehicles (e.g., the first vehicle) without decreasing the throughput parameter of the transportation network.
摘要:
A system includes an interface module, a simulation module, and a resolution module. The interface module determines a captured state of vehicles traveling in a transportation network according to associated schedules and a proposed modification to the schedules. The captured state represents locations of the vehicles in the transportation network at a selected time. The simulation module simulates movement of the vehicles according to the proposed modification to the schedules. The movement of the vehicles is simulated from the selected time of the captured state of the vehicles. The resolution module determines potential ramifications from the movement of the vehicles that is simulated. The potential ramifications are representative of a simulated change in travel of the vehicles due to the proposed modification. The resolution module is further configured to use the potential ramifications for use in determining whether to implement the proposed modification in actual travel of the vehicles.
