1. 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;
inferring a traffic law associated with the vehicle location based on a set of historical movement datasets collected at a set of mobile computing devices associated with historical driving sessions intersecting the vehicle location, wherein the historical driving sessions occur before the first time period;
wherein inferring the traffic law is performed at a remote computing system in communication with the mobile computing device;
receiving the inferred traffic law at the mobile computing device contemporaneously with the driving session;
at the mobile computing device, determining a traffic compliance parameter associated with the vehicle motion characteristic based on a comparison between the vehicle motion characteristic and the traffic law; and
in response to determining the traffic compliance parameter, initiating a traffic-related action.

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.
