Abstract

A computer readable medium embodies a program of machine-readable instructions executable by a processing apparatus to perform operations including determining information corresponding to a number of differences in distances between ending points of journeys taken by a vehicle and starting points of consecutive journeys taken by the vehicle, and transmitting one or more representations of the information. Another computer readable medium tangibly includes instructions for, for each of a number of vehicles, receiving one or more scores corresponding to a vehicle, and determining a ranked list containing at least a portion of the scores, and outputting the ranked list. Another computer readable medium includes instructions for, for each of a number of vehicles, receiving information corresponding to a vehicle, using one or more metrics, calculating one or more values from the received information, and communicating one or more representations of the one or more value to one or more entities.

Claims

1. A computer readable medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to cause the digital processing apparatus to perform operations comprising:

for each of a plurality of vehicles, receiving information corresponding to a vehicle;

using at least one metric, calculating at least one value from the received information; and

communicating at least one representation of the at least one value to at least one entity.

2. The computer readable medium of claim 1, wherein the at least one entity comprises at least one on board unit associated with at least one of the plurality of vehicles.

3. The computer readable medium of claim 1, wherein the information corresponding to a vehicle comprises information corresponding to a plurality of differences in distances between ending points of journeys taken by the vehicle and starting points of consecutive journeys taken by the vehicle.

4. The computer readable medium of claim 1, wherein:

calculating further comprises calculating a first value corresponding to a mean of data determined using the received information and a second value corresponding to a standard deviation determined using the data; and

transmitting further comprises transmitting at least one representation of the first and second values to at least one of the plurality of vehicles.

5. A computer readable medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to cause the digital processing apparatus to perform operations comprising:

for each of a plurality of vehicles, receiving at least one score corresponding to a vehicle;

determining a ranked list containing at least a portion of the scores; and

outputting the ranked list.

6. The computer readable medium of claim 5, wherein, for each of the plurality of vehicles, the at least one score corresponds to at least one metric applied to a plurality of differences in distances between ending points of journeys taken by one of the plurality of vehicles and starting points of consecutive journeys taken by the one vehicle.
