Abstract

A system described herein includes a receiver component that receives first velocity data that is indicative of a velocity of a vehicle over a period of time, wherein the first velocity data corresponds to a first sensor. The receiver component also receives second velocity data that is indicative of the velocity of the vehicle over the period of time, wherein the second velocity data corresponds to a second sensor. The system also includes a modifier component that determines a difference between the first velocity data and the second velocity data and outputs at least one final velocity value for the vehicle based at least in part upon the first difference data.
