Identifying significant locations based on vehicle probe data
First Claim
1. A vehicle, comprising:
- a processor configured to execute instructions stored on a non-transitory computer readable medium to;
identify vehicle transportation network information representing a vehicle transportation network, the vehicle transportation network information including destinations of a vehicle obtained by spatially clustering vehicle probe data;
for at least some of the destinations, perform density-based clustering using temporal data associated with the at least some of the destinations to form at least two spatio-temporal clusters; and
assign a contextual label to a location associated with a first spatio-temporal cluster of the at least two spatio-temporal clusters based on the temporal data associated with the first spatio-temporal cluster, the location being a labeled location; and
a vehicle operation device configured to operate the vehicle using the labeled location.

Abstract
A method, a vehicle and a system that identify and use a location significant to a person associated with a vehicle based on vehicle probe data are described. Vehicle transportation network information representing a vehicle transportation network is identified, the vehicle transportation network information including destinations of a vehicle obtained from vehicle probe data. For at least some of the destinations, density-based clustering is performed using temporal data associated with the at least some of the destinations to form at least two spatio-temporal clusters. A contextual label is assigned to a location associated with a first spatio-temporal cluster of the at least two spatial-temporal clusters based on the temporal data associated with the first spatio-temporal cluster, the location being a labeled location, and the labeled location is used for vehicle operation. The labeled location may be used for navigation or service, for example.

-
a memory including a non-transitory computer readable medium; and a processor configured to execute instructions stored on the non-transitory computer readable medium to; identify vehicle transportation network information representing a vehicle transportation network by performing spatial clustering of vehicle location information obtained from vehicle probe data of a vehicle, the vehicle transportation network information including destinations of the vehicle; perform two-dimensional density-based clustering using an arrival time of day and a stay time associated with at least some of the destinations to form a spatio-temporal cluster; assign a contextual label to a location associated with the spatio-temporal cluster based on temporal data associated with the spatio-temporal cluster, the location being a labeled location; and use the labeled location for vehicle operation. - View Dependent Claims (19, 20)
