1. A method, comprising:

  • receiving, by an autonomous driving system of an autonomous vehicle from an on-board diagnostics system associated with the autonomous vehicle, near real-time vehicle travel information corresponding to driving conditions experienced by the autonomous vehicle during travel along a route, wherein the near real-time vehicle travel information comprises vehicle sensor information received from one or more vehicle sensors associated with the autonomous vehicle;

    receiving, by the autonomous driving system of the autonomous vehicle, from a personal navigation device, a first travel route for the autonomous vehicle and a second travel route for the autonomous vehicle;

    determining, by the autonomous driving system of the autonomous vehicle, a first route risk value for the first travel route and a second route risk value for the second travel route, wherein the first route risk value and the second route risk value are determined based on a direction that the autonomous vehicle travels through a road segment and the near real-time vehicle travel information received from the on-board diagnostics system associated with the autonomous vehicle;

    comparing, by the autonomous driving system of the autonomous vehicle, the first route risk value to the second route risk value to identify a travel route of the first travel route and the second travel route having less route risk;

    selecting, by the autonomous driving system of the autonomous vehicle, the travel route of the first travel route and the second travel route identified as having the less route risk; and

    operating, by the autonomous driving system of the autonomous vehicle, one or more driving aspects of the autonomous vehicle based on the selected travel route, wherein operating the one or more driving aspects of the autonomous vehicle based on the selected travel route comprises controlling one or more of acceleration of the autonomous vehicle based on the selected travel route, deceleration of the autonomous vehicle based on the selected travel route, steering of the autonomous vehicle based on the selected travel route, or route navigation of the autonomous vehicle based on the selected travel route.
