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. |

1. A computer-implemented method of analyzing points of interest using traces from probe data, comprising:
providing a database of a digital vector map configured to store a plurality of traces representing roads of a navigable street network; collecting, by a processor, probe data from mobile device traveling along said traces; bundling, by a processor, a group of select traces having routes with a common origin and at least one divergence point downstream from said origin; building, by a processor, a database of mobile device maneuvers over said routes; computing, by a processor, at least one of average speeds, delay time, or delay profile, of said group of select traces of mobile devices traversing said mobile device maneuvers; computing, by a processor, at least one of average speeds, delay time, or delay profile, of all mobile devices traversing said mobile device maneuvers; comparing, by a processor, the at least one of average speeds, delay time, or delay profile from the group of select traces of mobile devices with the at least one of average speeds, delay time, or delay profile from all mobile devices traversing said mobile device maneuvers; and determining, by a processor, from said comparison, information associated with one or more points of interest along said routes. |
