20130116916 | TRANSPORTATION NETWORK SCHEDULING SYSTEM AND METHOD - 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. | 05-09-2013 |
20130144466 | TRANSPORTATION NETWORK SCHEDULING SYSTEM AND METHOD - 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. | 06-06-2013 |
20130144467 | TRANSPORTATION NETWORK SCHEDULING SYSTEM AND METHOD - 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. | 06-06-2013 |
20130144517 | SYSTEM AND METHOD FOR MODIFYING SCHEDULES OF VEHICLES - 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. | 06-06-2013 |
20130144670 | SYSTEM AND METHOD FOR ALLOCATING RESOURCES IN A NETWORK - A system includes first and second allocation units that allocate resources in a network according to respective first and second selected allocations for driving the resources toward a respective first or second goal conditions. At least one of the first or second allocation unit is configured to generate and provide feedback data to the other of the first or second allocation unit. The feedback data represents a difference between an actual allocation of the one or more resources and the corresponding first or second selected allocation. At least one of the first or second allocation unit is configured to change the corresponding first or second selected allocation to change how the resources are allocated in the network based on the feedback data. | 06-06-2013 |
20130151133 | SYSTEM AND METHOD FOR PLANNING MOVEMENT OF VEHICLES - A method includes determining an operational parameter of a first vehicle traveling with a plurality of vehicles in a transportation network and/or a route in the transportation network, identifying a failure condition of the first vehicle and/or the route based on the operational parameter, obtaining plural different sets of remedial actions that dictate operations to be taken based on the failure condition, simulating travel of the plurality of vehicles in the transportation network based on implementation of the different sets of remedial actions, determining potential consequences on travel of the plurality of vehicles in the transportation network when the different sets of remedial actions are implemented in the travel that is simulated, and, responsive to the potential consequences, receiving a selection of at least one of the different sets of remedial actions to be implemented in actual travel of the plurality of vehicles in the transportation network. | 06-13-2013 |
20130158742 | SYSTEM AND METHOD FOR COMMUNICATING IN A TRANSPORTATION NETWORK - A system includes a communication unit configured to communicate with a scheduling system that determines schedules for plural vehicles to travel in a transportation network and with a control system that forms a trip plan for a first vehicle of the plural vehicles comprising operational settings for controlling movement of the first vehicle during a trip in the transportation network. The communication unit is configured to convey information between the scheduling system and the control system such that the scheduling system coordinates the schedules of the vehicles to maintain a throughput parameter of the transportation network and the control system forms the trip plan that reduces at least one of an amount of fuel consumed or an amount of emissions generated by the first vehicle during the trip according to the schedule associated with the first vehicle. | 06-20-2013 |
20140136025 | Transportation Network Scheduling System And Method - 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. | 05-15-2014 |
