Abstract
A method for traffic characterization associated with a vehicle including collecting a movement dataset sampled at least at one of a location sensor and a motion sensor associated with the vehicle, during a driving session associated with movement of the vehicle; extracting a set of features from the movement dataset associated with movement of the vehicle during the driving session; and determining one or more traffic-related characteristics associated with the vehicle based on the set of features.
Claims20
A method for traffic compliance characterization with a mobile computing device located within a vehicle, comprising:
- collecting a first location dataset at a location sensor of the mobile computing device during a driving session defining a first time period of movement of the vehicle, wherein the mobile computing device is associated with a user;
- collecting a first motion dataset at a motion sensor of the mobile computing device during the driving session;
- extracting a vehicle motion characteristic from at least one of the location dataset and the motion dataset;
- extracting a vehicle location from the location dataset;
- at a remote computing system in communication with the mobile device, inferring that a visual traffic indicator is located proximal the vehicle location based on the vehicle motion characteristic;
- at the remote computing system, determining a traffic rule associated with the visual traffic indicator based on the vehicle motion characteristic;
- mapping the visual traffic indicator and the associated traffic rule to the vehicle location, and storing the visual traffic indicator and the associated traffic rule in association with the vehicle location at a traffic rule map of the remote computing system.
A method for traffic compliance characterization with a mobile computing device located within a vehicle, comprising:
- collecting a first location dataset at a GPS sensor of the mobile computing device during a driving session defining a first time period of movement of the vehicle, wherein the mobile computing device is associated with a user;
- collecting a first motion dataset at an accelerometer of the mobile computing device during the driving session;
- extracting a vehicle motion characteristic from at least one of the location dataset and the motion dataset;
- extracting a vehicle location from the location dataset;
- retrieving an inferred traffic rule associated with the vehicle location from a traffic rule map stored at a remote computing system;
- determining a traffic compliance parameter associated with the vehicle motion characteristic based on a comparison between the inferred traffic rule and the vehicle motion characteristic;
- and
- in response to determining the traffic compliance parameter, initiating a traffic-related action.
