Abstract
A system and method for combining sequential map segments to aggregate, analyze, and display traffic data collected from one or more probe vehicles located on one or more segments of road are provided. Vehicle travel data generation and storage are provided by a data processing center, partitioning a road into a plurality of connected segments, and calculating an estimate of the time required for a probe vehicle to traverse a particular segment. The calculations are performed by a processor that may be on-board the probe vehicle, and the resulting data are transmitted to the processing center, at which they are aggregated and optionally transmitted to one or more subscriber vehicles.
