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.

Abstract: A system comprising one or more computing devices implements a vehicle information extraction service. The vehicle information extraction service enables customers to provide access to proprietary encoding protocols used by the customers to communicate over a bus of a vehicle, wherein the proprietary protocols are used by the vehicle information extraction service to perform vehicle information monitoring, while at the same time protecting the confidentiality of the proprietary protocols from being accessed by third parties. Also, the vehicle information extraction service enables streaming of relevant vehicle information corresponding to customer defined event criteria without requiring non-relevant vehicle information to be streamed, which would consume considerable network resources.

Abstract: A system and method adjusts road segment boundaries based on information received from devices that travel a road system for purposes other than road segment definition.

Abstract: A system and method provides location-aware search results from a navigation or other device and provides one or more enhanced listings or advertisements with the results to offset the communication cost of the search. The sponsor may be charged for the listing or advertisement and the charge may be based on whether the device arrives in an area around the sponsor location within a threshold amount of time.

Abstract: A system and method uses a communication request and/or historical data collected by one or more devices to identify whether to fulfill the request using ad hoc networking or access points. If an access point is determined to be used, the system and method attempts to identify those access points that can best fulfill the request and then attempts to use such access points to fulfill the request.

Abstract: A hierarchical floating car data network comprises a central server, an egress point network, and a participating vehicle network. The egress point network is in communication with the central server. The egress point network comprises a plurality of egress points. The participating vehicle network comprises a plurality of participating vehicles. At least some of the plurality of participating vehicles are in direct communication with each other. At least some of the plurality of participating vehicles are in communication with at least some of the plurality of egress points. Furthermore, at least some of the plurality of participating vehicles may be in communication with the central server. A geographic database is formed from content communicated between the elements of the hierarchical floating car data network.

Abstract: An enhanced mobile communication device communicates directly with other enhanced mobile communication devices in an ad-hoc mode over a wireless medium. The device transmits and receives packets of digital data. The packets of digital data are such that when transmitted, the probability that they will be received by the other mobile communication devices is increased. The probability is further increased by transmitting the packets a multiple and variable number of times according activity in the wireless medium. Attempts to transmit are made periodically and the period of transmission is adjusted according to activity in the wireless medium. In a transportation application, the packets comprise vehicle traffic congestion update information. The device maintains a traffic database and a map database. Traffic congestion update information is exchanged with other devices.

Abstract: A system and method splices into, or replaces routes identified based on road geometry with routes taken by the same user or other users to create alternate routes that may be selected by a user to display, for example, on a map or for which driving directions can be displayed. Communication of routes traveled by different devices may be received from a server or from another device. A naming convention for road segments and ordered paths of road segments is described.

Abstract: A system and method detects an amount of data attributed to a device including reports sent to the device, and reduces the amount of data being used to provide reports to the device if the amount of data attributed to the device exceeds an amount assigned to the device. Data uploaded from the device is also minimized.
