Inferring a behavioral state of a vehicle

A computer-implemented method, comprising:

• under control of one or more computer systems containing memory and configured with executable instructions stored in the memory,
• determining a trajectory of a vehicle based at least in part on trajectory data representing tracked positions of the vehicle, the trajectory data including recorded times, and speed of the vehicle at the positions along the trajectory;
• accessing previously-recorded traffic patterns of vehicles along the trajectory;
• and
• inferring, by the one or more computer systems, a state of the vehicle based at least in part on the trajectory and the previously-recorded traffic patterns, the state of the vehicle including at least one of:
• an occupied state, in which the vehicle is transporting a passenger, and a non-occupied state, in which the vehicle is traveling without a passenger.

A system, comprising:

• one or more processors;
• a memory communicatively coupled to the one or more processors;
• and
• an application at least partially stored in the memory and executable on the one or more processors, the application including:
• a first module configured to process a trajectory of a vehicle based at least in part on a tracked position of the vehicle, the tracked position of the vehicle including spatial-temporal data;
• the first module further configured to identify one or more potential parking locations of the vehicle along the trajectory and divide the trajectory into segments based, at least in part, on knowledge of the identified potential parking locations;
• a second module configured to map-match attributes from the segments to corresponding road segments;
• a third module configured to access historical data representative of previously-recorded traffic patterns of vehicles along the trajectory;
• wherein the first, second, and third, modules form a collective module configured to infer a state of the vehicle based on the spatio-temporal data associated with the trajectory, map-matched attributes, and the historical data, the state of the vehicle including at least one of:
• an occupied state in which the vehicle is transporting at least one passenger, and a non-occupied state in which the vehicle is traveling without a passenger.
