Velocity information can be beneficial to various entities including other vehicles and a central traffic monitoring and routing system. Vehicles with sensors can serve as velocity probes to update speeds that are shared via a more global service. However, individuals may be reluctant to provide location and velocity information given privacy preferences. Local policies about sharing personal data are described that can be harnessed to enhance privacy while minimizing communication costs. The local data-sharing policies allow devices to monitor their own speeds and locations and to employ models and analyses that determine the value of sharing flow information with a larger service in accordance with privacy preferences, and to make local decisions as to when to respond to broadcasted queries for specific information, while minimizing the redundancy of signals from multiple vehicles.

Described is a technology in which Bluetooth&#xae; devices, e.g., navigation devices, are enhanced with additional power amplification to allow long range radio communication links between moving vehicles and/or between moving vehicles and roadside hubs. In one example, collection and dissemination of traffic information, including aggregation and filtering, is facilitated via a Bluetooth&#xae; vehicle-to-vehicle and/or vehicle-to-roadside hub ad-hoc network. Also described is efficient connection establishment and data transfer for vehicle to vehicle and vehicle-to-roadside hubs via the enhanced Bluetooth&#xae; radio. The ad-hoc network comprising a mesh of vehicles/a supernode also facilitates the exchange of information that originated at an Internet source.
