1. A computer-implemented method for vehicle accident avoidance carried out with respect to a host vehicle, comprising:

  • monitoring a surrounding environment of the host vehicle;

    detecting other vehicles in the surrounding environment of the host vehicle by at least one visual sensor;

    estimating a speed and direction of each of the detected vehicles;

    calculating one or more projected paths of each of the detected vehicles based on their current estimated speed and direction, the monitored surrounding environment, and other detected vehicle projected paths, wherein the calculating further comprises;

    uniquely identifying a detected vehicle;

    retrieving a historical-data-based model for the uniquely identified, detected vehicle, the historical-data-based model comprising historical vehicle travel route data and historical vehicle-moving behavioral data along those routes for the uniquely identified, detected vehicle; and

    generating one or more projected paths for the uniquely identified, detected vehicle based, at least in part, on the historical-data-based model for the uniquely identified, detected vehicle, including the historical vehicle travel route data and the historical vehicle-moving behavioral data along those routes;

    estimating a probability of intersection of each projected path with the host vehicle; and

    providing an alert or action to the host vehicle if there is a high probability of intersection.
