Route risk mitigation

A method, comprising:

• at a personal computing device comprising a processor and a memory:
• calculating, by the processor, a route of a vehicle from a start location to an end location based on locations received from a location detection device, wherein the personal computing device is located in the vehicle, and wherein the location detection device is located in the vehicle and configured to monitor a current location of the vehicle during travel;
• identifying, by the processor, a plurality of roads associated with the route of the vehicle;
• determining, by the processor, a plurality of road segments for each road associated with the route of the vehicle, wherein determining the plurality of road segments for each road associated with the route of the vehicle comprises determining, based on historical accident information, a length of each segment of the plurality of road segments to create segment lengths based on normalized risk values;
• calculating, by the processor, based on vehicle direction through each road segment of the plurality of road segments and the length of each segment of the plurality of road segments, a route risk score for the route of the vehicle, wherein at least one road segment of the plurality of road segments has a higher risk score for the vehicle travelling in a first direction and a lower risk score for the vehicle traveling in a second direction opposite to the first direction;
• displaying, by the processor, the calculated route and the route risk score on an output device;
• and
• adjusting, by the processor, the route risk score upon completion of the route being traveled by the vehicle based on vehicle conditions experienced during travel along the route.

One or more non-transitory computer-readable media storing instructions that, when executed by a personal computing device comprising a processor and a memory, cause the personal computing device to:

• calculate a route of a vehicle from a start location to an end location based on locations received from a location detection device, wherein the personal computing device is located in the vehicle, and wherein the location detection device is located in the vehicle and configured to monitor a current location of the vehicle during travel;
• identify a plurality of roads associated with the route of the vehicle;
• determine a plurality of road segments for each road associated with the route of the vehicle, wherein determining the plurality of road segments for each road associated with the route of the vehicle comprises determining, based on historical accident information, a length of each segment of the plurality of road segments to create segment lengths based on normalized risk values;
• calculate, based on vehicle direction through each road segment of the plurality of road segments and the length of each segment of the plurality of road segments, a route risk score for the route of the vehicle, wherein at least one road segment of the plurality of road segments has a higher risk score for the vehicle travelling in a first direction and a lower risk score for the vehicle traveling in a second direction opposite to the first direction;
• display the calculated route and the route risk score on an output device;
• and
• adjust the route risk score upon completion of the route being traveled by the vehicle based on vehicle conditions experienced during travel along the route.
