Abstract

Aspects of the present invention relate to path determination for vehicle infrastructure paths. In embodiments, methods and systems are provided for identifying alternative paths and determining optimized vehicle paths for projects. The methods and systems may involve providing a client-based application having a GUI that presents a plurality of constraints that relate to a project, and a server-based application for calculating the costs of a plurality of potential paths for presenting a subset of paths with associated cost data

Claims

1. The method for identifying alternative paths for projects, comprising:

providing a client-based application having a GUI that presents a plurality of constraints that relate to a project;

a server-based application for calculating the costs of a plurality of potential paths for presenting a subset of paths with associated cost data; and

determining an optimized path for at least one of a road, a railway, and an infrastructure that enables movement of vehicles.

2. The method of claim 1, wherein a sensitivity analysis is undertaken by iteratively varying factors in multiple scenarios and comparing results in a consistent format.

3. The method of claim 1, wherein a simultaneous consideration of environmental and community constraints, engineering parameters, unit costs, and land acquisition costs is undertaken.

4. The method of claim 1, wherein selection of a corridor or path is achieved through an iterative process of avoiding constraints based on a priority/importance basis.

5. The method of claim 1, wherein costs include costs associated with geological zones.

6. The method of claim 1, wherein culvert zones may be defined for crossing flood plains or areas that experience sheet water flows.

7. The method of claim 1, wherein compaction factors and percentage of a material that is reusable for fill once extracted may be defined.

9. The method of claim 1, wherein earthwork volumes may be calculated with benches being automatically inserted, as defined by the user for each geology and strata, from the alignment, up or down, to the land surface.

12. The method of claim 1, further comprising avoiding predefined objects that have line of sight capability between another object and the infrastructure path.

13. The method of claim 1, wherein the line of sight relates to the safe line of sight distance for a vehicle on a road.

19. A system for identifying alternative paths and determining optimized paths for projects, comprising:

a client-based application having a GUI that presents a plurality of constraints that relate to a project;

a server-based application for calculating the costs of a plurality of potential paths for the projects and presenting a subset of paths with associated cost data; and

determining an optimized path for at least one of a road, a railway, and an infrastructure that enables movement of vehicles.

20. The system of claim 19, wherein a sensitivity analysis is undertaken by iteratively varying factors in multiple scenarios and comparing results in a consistent format.

21. The system of claim 19, wherein a simultaneous consideration of environmental and community constraints, engineering parameters, unit costs, and land acquisition costs is undertaken.

22. The system of claim 19, wherein selection of a corridor or path is achieved through an iterative process of avoiding constraints based on a priority/importance basis.

23. The system of claim 19, wherein costs include costs associated with geological zones.

24. The system of claim 19, wherein culvert zones may be defined for crossing flood plains or areas that experience sheet water flows.

25. The system of claim 19, wherein compaction factors and percentage of a material that is reusable for fill once extracted may be defined.

27. The system of claim 19, wherein earthwork volumes may be calculated with benches being automatically inserted, as defined by the user for each geology and strata, from the alignment, up or down, to the land surface.

30. The system of claim 19, further comprising predefined object avoidance for line of sight capability between another object and the infrastructure path.

31. The system of claim 19, wherein the line of sight relates to the safe line of sight distance for a vehicle on a road.

37. A method of land valuation, comprising:

selecting a path;

defining a land area of the path;

determining an alternative path that avoids the land area;

comparing the cost of the original path to the cost of the alternative path to determine the change in cost resulting from the alternative path; and

calculating a path-relative value for the land area.
