Abstract

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.

Claims

1. A method comprising:

forming a first schedule for a first vehicle to travel in a transportation network, the first schedule including a first arrival time of the first vehicle at a scheduled location;

receiving a first trip plan for the first vehicle from an energy management system, the first trip plan based on the first schedule and designating 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; and

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.

2. The method of claim 1, further comprising modifying the first schedule into a different, modified second schedule based on the trip plan and communicating the modified second schedule to the first vehicle.

3. The method of claim 2, further comprising receiving a different, modified second trip plan for the first vehicle that is based on the modified second schedule and determining whether to modify the modified second schedule based on the modified second trip plan.

4. The method of claim 1, further comprising tracking actual movement of the first vehicle in the transportation network and modifying the first schedule of the first vehicle based on the actual movement.

5. The method of claim 1, further comprising communicating the first schedule to the energy management system that is disposed on-board the first vehicle so that the energy management system can form the trip plan based on the first schedule.

6. The method of claim 1, further comprising modifying the first schedule to avoid at least one of a meet event or a pass event between the first vehicle and one or more other vehicles.

7. The method of claim 6, wherein modifying the first schedule includes delaying a time that the first vehicle is to arrive at a siding section route for the at least one of the meet event or the pass event.

8. A method comprising:

transmitting plural respective first schedules to plural vehicles in a transportation network;

receiving plural respective initial trip plans from the plural vehicles responsive to the first schedules; and

transmitting plural respective modified schedules of the first schedules to the vehicles, for the vehicles to generate modified trip plans for controlling the vehicles, if control of the vehicles according to the initial trip plans would result in interference with vehicle movement in the transportation network.

9. A system comprising:

a scheduling unit configured to form a first schedule for a first vehicle to travel in a transportation network, the first schedule including a first arrival time of the first vehicle at a scheduled location; and

a communication unit configured to receive a first trip plan for the first vehicle from an energy management system, the first trip plan based on the first schedule and designating 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;

wherein the scheduling unit is configured to determine 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.

10. The system of claim 9, wherein the scheduling unit is configured to modify the first schedule into a different, modified second schedule based on the trip plan and the communication unit is configured to communicate the modified second schedule to the first vehicle.

11. The system of claim 10, wherein the communication unit is configured to receive a different, modified second trip plan for the first vehicle that is based on the modified second schedule and the scheduling unit is configured to determine whether to modify the modified second schedule based on the modified second trip plan.

12. The system of claim 9, further comprising a tracking unit configured to monitor actual movement of the first vehicle in the transportation network, wherein the scheduling unit is configured to modify the first schedule of the first vehicle based on the actual movement.

13. The system of claim 9, wherein the communication unit is configured to communicate the first schedule to the energy management system that is disposed on-board the first vehicle so that the energy management system can form the trip plan based on the first schedule.

14. The system of claim 9, wherein the scheduling unit is configured to modify the first schedule to avoid at least one of a meet event or a pass event between the first vehicle and one or more other vehicles.

15. The system of claim 14, wherein the scheduling unit is configured to modify the first schedule by delaying a time that the first vehicle is to arrive at a siding section route for the at least one of the meet event or the pass event.

16. A method comprising:

receiving a first schedule for a first vehicle to travel in a transportation network from a scheduling system, the first schedule including a first arrival time of the first vehicle at a scheduled location;

forming a first trip plan for the first vehicle based on the first schedule, the trip plan designating 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; and

communicating the first trip plan to the scheduling system so that the scheduling system can examine the first trip plan and determine whether to modify the first schedule based on the first trip plan.

17. The method of claim 16, further comprising receiving a different, modified second schedule from the scheduling system that is based on the first trip plan and forming a different, modified second trip plan based on the modified second schedule.

18. The method of claim 17, further comprising communicating the second trip plan to the scheduling system to enable the scheduling system to determine whether to modify the modified second schedule based on the modified second trip plan.

19. The method of claim 16, further comprising reporting location information of the first vehicle to the scheduling system to permit the scheduling system to modify the first schedule of the first vehicle based on the location information.

20. A system comprising:

a communication unit configured to receive a first schedule for a first vehicle to travel in a transportation network from a scheduling system, the first schedule including a first arrival time of the first vehicle at a scheduled location; and

an energy management unit configured to form a first trip plan for the first vehicle based on the first schedule, the trip plan designating 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;

wherein the communication unit is configured to communicate the first trip plan to the scheduling system so that the scheduling system can examine the first trip plan and determine whether to modify the first schedule based on the first trip plan.

21. The system of claim 20, wherein the communication unit is configured to receive a different, modified second schedule from the scheduling system that is based on the first trip plan and the energy management unit is configured to form a different, modified second trip plan based on the modified second schedule.
