Abstract: A system comprising one or more computing devices implements a vehicle information extraction service. The vehicle information extraction service enables customers to optimize an amount of relevant vehicle sensor information extracted from vehicles by reducing instances of collection of redundant data. The vehicle information extraction service additionally, or alternatively, enables customers to maintain a model of a fleet of vehicles and determine number of the vehicles of the fleet in a certain partition to calculate a data reduction factor that will filter out sensor data. The vehicle information extraction service communicates the reduction factor to the vehicles in the geographical region using a vehicle scheme to indicate to the vehicles the probability with which the vehicle is to transmit a particular type of sensor data.
