Benefits of technology
The patent text describes a system and method for determining a route warranty for vehicle systems in a transportation network. This means that the system determines multiple paths for the vehicle to travel from one location to another, and checks if those paths pass certain tests to ensure that the vehicle system can only travel on those paths. This prevents other vehicle systems from using those paths, ensuring that the warranty is being upheld. The technical effect of this is that it provides a more efficient and organized approach to travel in a transportation network, ensuring safety and reliability for vehicle systems.
Problems solved by technology
As a result, the consideration of only the tracks and switches that are on or near the direct line between starting and ending locations for the trip can pose many scheduling problems.

Embodiment Construction
[0020]Embodiments of the inventive subject matter described herein relate to methods and systems for determining route warrants for vehicle systems. Route warrants are used to authorize vehicle systems (such as trains) to occupy routes, such as main tracks located outside of the limits of rail yards. Different authorities (e.g., scheduling systems, dispatchers, etc.) dictate movement of the vehicle systems in different areas (which may or may not overlap with each other). The systems and methods described herein provide validation logic to authorize vehicle systems for passage along the routes while ensuring that the limits of one authority do not overlap with another authority.
[0021]In one aspect, the systems and methods described herein can represent a transportation network formed of several interconnected routes as a series of associated nodes connected through paths stored in one or more memory structures (e.g., tables, lists, etc.). The nodes can represent intersections betwee...

A method for determining a route warranty for one or more vehicle systems includes determining plural different paths for a trip of a first vehicle system from an origin location to a destination location in a transportation network formed from paths interconnected with each other at nodes, determining whether travel by the first vehicle system along the different routes fails one or more tests that restrict how the first vehicle system travels in the transportation network, and determining a route warranty for the first vehicle system based on the one or more tests. The route warranty reserves one or more of the paths for travel by the first vehicle system from the origin location to the destination location such that other vehicle systems are prevented from traveling on the one or more of the paths reserved by the route warranty.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. application Ser. No. 15 / 170,828, filed on Jun. 1, 2016, which claims the benefit of U.S. Provisional Application No. 62 / 170,250, filed on Jun. 3, 2015.FIELD[0002]Embodiments of the subject matter disclosed herein relate to determining route warrants for vehicle systems traveling in a transportation network.BACKGROUND[0003]Transportation networks formed from many interconnected routes may be concurrently traveled by several different vehicles. For example, networks of tracks may be traveled by many trains at the same time. In order to ensure safe and timely travel of the trains, track warranties may be issued for the trains. The track warrants can designate which tracks and switches are to be traveled over by the trains at various times. Typically, different dispatch facilities control movement of trains in areas governed by the different dispatch facilities use different track warrants to control w...
