Abstract
There are provided methods and systems for road wear leveling. A method includes determining a location of a velocity change point based on wear leveling information for a road segment including the location. The method further includes communicating the location of the velocity change point to a vehicle.
Claims25
A road wear leveling method, comprising:
- determining, using a velocity change point determining unit or a receiving device, a location of a velocity change point based on wear leveling information for a road segment including the location;
- and
- communicating, using at least one of one or more external location indicating devices and one or more internal location indicating devices with respect to the vehicle, the location of the velocity change point to a vehicle,
- wherein the method is performed for a fixed and single traversal path with respect to the road segment.
1 more element
A road wear leveling system for performing a road wear leveling method, the system comprising:
- a velocity change point determining unit for determining a location of a velocity change point based on wear leveling information for a road segment including the location;
- and
- a communication system for communicating the location of the velocity change point to a driver of the vehicle,
- wherein the method is performed for a fixed and single traversal path with respect to the road segment.
1 more element
A road wear leveling method, comprising:
- receiving, using a receiving device, at least one of vehicle passage information, road maintenance information, road profile measurements, induction loop data from induction loops embedded in the road segment, and normative road wear profiles relating to expected wear condition for the road segment;
- determining, using a velocity change point determining unit, a location of a velocity change point based on wear leveling information for a road segment including the location, the wear leveling information determined responsive to said receiving step;
- controlling, selectively using an enforcement system, one or more vehicle functions in accordance with the location of the velocity change point,
- wherein the method is performed for a fixed and single traversal path with respect to the road segment.

- a receiving device for receiving at least one of vehicle passage information, road maintenance information, road profile measurements, induction loop data from induction loops embedded in the road segment, and normative road wear profiles relating to expected wear condition for the road segment;
- a velocity change point determining unit for determining a location of a velocity change point based on wear leveling information for a road segment including the location, the wear leveling information determined responsive to an output of said receiving device;
- and
- an in-vehicle enforcement system connected to one or more vehicle systems for implementing a velocity change at the determined location,
- wherein the method is performed for a fixed and single traversal path with respect to the road segment.
