Abstract

Data indicating current driving characteristics of a driver driving a vehicle can be received in real time. A driving profile for the driver can be determined based on the data. The driving profile can be categorized into a driving pattern category. A plurality of candidate travel routes for the driver to reach an intended destination can be identified and, for each of the candidate travel routes, a plurality of route segments can be identified. Based on the driving pattern category, a probability that the current driving characteristics of the driver will cause a traffic accident can be determined for each of the plurality of route segments. Route segments for which the probability that the current driving characteristics of the driver will cause the traffic accident exceeds a threshold value can be determined. A notification can be communicated to the driver or vehicle indicating such probability.

Claims

1. A method, comprising:

receiving, in real time, data indicating current driving characteristics of a driver driving a vehicle, the data indicating the current driving characteristics being generated, at least in part, by a plurality of sensors in the vehicle;

based on the data indicating the current driving characteristics of the driver, determining a driving profile for the driver;

categorizing the driving profile for the driver into a driving pattern category;

determining an intended destination of the driver driving the vehicle;

identifying a plurality of candidate travel routes for the driver to reach the intended destination and, for each of the candidate travel routes, identifying a plurality of route segments;

based on the driving pattern category into which the driving profile is categorized, determining, using a processor, for each of the plurality of route segments, a probability that the current driving characteristics of the driver will cause a traffic accident;

determining the route segments for which the probability that the current driving characteristics of the driver will cause the traffic accident exceeds a threshold value; and

communicating to the driver or the vehicle a notification indicating that the probability that the current driving characteristics of the driver will cause the traffic accident exceeds the threshold value on the determined route segments.

2. The method of claim 1, further comprising:

determining at least one of the plurality of candidate routes comprising the route segments for which the probability that the current driving characteristics of the driver will cause the traffic accident does not exceed the threshold value; and

communicating to the driver or the vehicle a notification indicating a suggestion to travel the determined at least one of the plurality of candidate routes.

3. The method of claim 1, further comprising:

determining whether the driving profile for the driver fits an existing driving pattern category; and

responsive to determining that the driving profile for the driver does not fit the existing driving pattern category, automatically creating a new driving pattern category in which the driving profile for the driver fits;

wherein categorizing the driving profile for the driver into the driving pattern category comprises categorizing the driving profile for the driver into the new driving pattern category.

4. The method of claim 1, further comprising:

identifying at least one event currently affecting travel on at least one of the plurality of route segments;

wherein determining the probability that the current driving characteristics of the driver will cause the traffic accident is based, in part, on the event affecting travel on at least one of the plurality of route segments.

5. The method of claim 1, wherein the driving profile for the driver further is based on historical driving characteristics generated for the driver, on at least one previous day, within a time window that includes a time of day that is a same time of day as a current time.

6. The method of claim 5, wherein the at least one previous day is a same day of a week as a current day.

7. The method of claim 1, further comprising:

determining a road type for at least one of the plurality of route segments;

wherein the driving pattern category is defined for that road type.

8. The method of claim 1, further comprising:

determining a current weather condition or temperature on at least one of the plurality of route segments;

wherein the driving pattern category is defined for that weather condition or temperature.
