(EN) METHOD OF ANALYZING POINTS OF INTEREST WITH PROBE DATA
Abrégé
(EN)

A method of analyzing points of interest (22) using traces from probe data is provided. The method includes providing a database of a digital vector map (18) configured to store a plurality of traces (1′-14′) representing roads. The method further includes collecting probe data from vehicles traveling along the traces. Then, bundling a group of select traces (2′, 5′, 7′, 9′, 11′) having routes with a common origin (20) and at least one divergence point (24, 1) downstream from the origin (20) and building a database of vehicle maneuvers over the routes. Further, computing average speeds and delay times of a random population of vehicles traversing the vehicle maneuvers. Further yet, computing average speeds and delay times of all vehicles traversing the routes. Then, comparing the computed results from the random population of vehicles with the computed results from all vehicles traversing said routes.
