Abstract
A mobile computing device is described that provides navigational guidance with lane-level granularity. The mobile computing device may be configured to measure and transmit its respective traffic data, which may include an indication of a vehicle road lane in which a vehicle is currently travelling, the speed of the vehicle driving in this road lane, and/or an indication of how long it takes for the vehicle to pass through various intersections in various lanes. The traffic data may be transmitted from several mobile computing devices to a traffic aggregation service, which may calculate an average vehicle speed and average intersection timing on a per-road lane basis. The traffic service may broadcast the averaged data to one or more mobile computing devices configured to receive this information. The mobile computing devices may use the averaged data to optimize routing and/or to improve the accuracy in which route driving times are calculated.
