1. A method for near-collision analysis, comprising, at an on-board system mounted to a vehicle:

  • recording an external video with an external-facing camera of the on-board system;

    determining obstacle parameters for an obstacle detected in the external video;

    generating a spatial risk map for the vehicle based on the obstacle parameters, the spatial risk map comprising a risk score for each of a plurality of spatial positions relative to the vehicle wherein the risk score is determined using;

    a parametric model comprising a set of Gaussian models;

    the obstacle parameters; and

    driver parameters extracted from an internal video recorded by an internal-facing camera of the on-board system;

    detecting a near-collision event when a risk score within the spatial risk map exceeds a risk threshold;

    labeling the near-collision event with a label determined based on the driver parameters;

    determining a cause of the near-collision event, comprising identifying an independent parameter of the parametric model with a highest weighted value; and

    transmitting the label to a remote computing system.
