1. A method of determining energy used on a transportation segment comprising:
- determining if a vehicle has had an initial fill-up with a fuel;
tracking the transportation segment the vehicle travels;
storing the transportation segment in a storage device;
determining if the vehicle has had a subsequent fill up with the fuel;
normalizing distance traveled from the initial fill-up to the subsequent fill-up with the fuel;
adding the transportation segment to a linear programming application; and
if sufficient transportation segments are present;
solving the linear programming application to determine a cost of the transportation segment.

Abstract
A method of using locational information for vehicles to determine the cost of traveling on transportation segments is disclosed. The transportation segment costs calculated may be used for many purposes such as providing the lowest cost travel path between two locations at a given time or in general. The cost also may be used to assign tolls and congestion pricing. In addition, the data may be used to determine when a certain vehicle has become less efficient and may require maintenance.

16. A computing system comprising a processor physically configured in accordance with computer executable instructions for determining energy used on a transportation segment, a memory physically confirmed to store computer executable instructions and an input/output circuit, the computer executable instructions comprising instructions for:
-
determining if a vehicle has had an initial fill-up with a fuel; tracking the transportation segment the vehicle travels; storing the transportation segment in a storage device; determining if the vehicle has had a subsequent fill up with the fuel further comprises determining if the vehicle has stopped at a known filling station for a sufficient time to fill the vehicle; normalizing distance traveled from the initial fill-up to the subsequent fill-up with the fuel; adding the transportation segment to a linear programming application; and if sufficient transportation segments are present;
solving the linear programming application to determine a cost of the transportation segment. - View Dependent Claims (17, 18, 19, 20)
