ROUTE SAFETY SCORE

1 . A system, comprising:

an input interface configured to receive sensor-collected speed data of a vehicle in a group of vehicles, wherein the speed data is associated with a plurality of route segments; and

a processor configured to:

determine a speed distribution of vehicles in the group of vehicles based at least in part on the received speed data;

determine a lane change frequency of the vehicle based at least in part on the received speed data;

determine a route segment safety score for each of the plurality of route segments based at least in part on the speed distribution and the lane change frequency vehicle;

determine a recommended route based at least in part on the determined route segment safety scores; and

output the recommended route.

2 . The system of claim 1 , wherein the speed distribution includes (i) speeds of vehicles in a first sub-group of vehicles travelling through a first location in a route segment and (ii) speeds of vehicles in a second sub-group of vehicles travelling through a second location in the route segment.

3 . The system of claim 2 , wherein the speed distribution comprises a distribution of speeds of vehicles within the route segment at a single point in time.

4 . The system of claim 2 , wherein the speed distribution comprises a distribution of typical vehicle speed within the route segment at different points in time.

5 . The system of claim 1 , wherein the input interface is further configured to receive at least one of: event data, maneuver data, video data, lane change frequency data, climate data, topology data, road data, and number of lanes data.

6 . The system of claim 1 , wherein the processor is further configured to determine the plurality of route segments that together form an associated route.

7 . The system of claim 6 , wherein the processor is further configured to determine a route safety score based at least in part on route segment safety scores for each route segment forming the route.

8 . The system of claim 7 , wherein the processor is further configured to:

determine another route safety score for a different route; and

compare the other route safety score with the route safety score.

9 . The system of claim 8 , wherein determining the recommended route is based at least in part on the comparison of the other route safety score with the route safety score.

10 . The system of claim 1 , wherein the input interface is further configured to receive a route, and the processor is further configured to determine the plurality of route segments based at least in part on the received route.

11 . A method for scoring route safety, comprising:

receiving sensor-collected speed data of a vehicle in a group of vehicles, wherein the speed data is associated with a plurality of route segments;

determining a speed distribution of vehicles in the group of vehicles based at least in part on the received speed data;

determining a lane change frequency of the vehicle based at least in part on the received speed data;

determining a route segment safety score for each of the plurality of route segments based at least in part on the speed distribution and the lane change frequency vehicle;

determining a recommended route based at least in part on the determined route segment safety scores; and

outputting the recommended route.

12 . The method of claim 11 , wherein the speed distribution includes (i) speeds of vehicles in a first sub-group of vehicles travelling through a first location in a route segment and (ii) speeds of vehicles in a second sub-group of vehicles travelling through a second location in the route segment.

13 . The method of claim 11 , further comprising determining the plurality of route segments that together form an associated route.

14 . The method of claim 13 , wherein further comprising determining a route safety score based at least in part on route segment safety scores for each route segment forming the route.

15 . The method of claim 14 , further comprising:

determining another route safety score for a different route; and

comparing the other route safety score with the route safety score.

16 . The method of claim 15 , wherein determining the recommended route is based at least in part on the comparison of the other route safety score with the route safety score.

17 . A computer program product for scoring route safety, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving sensor-collected speed data of a vehicle in a group of vehicles, wherein the speed data is associated with a plurality of route segments;

determining a speed distribution of vehicles in the group of vehicles based at least in part on the received speed data;

determining a lane change frequency of the vehicle based at least in part on the received speed data;

determining a route segment safety score for each of the plurality of route segments based at least in part on the speed distribution and the lane change frequency vehicle;

determining a recommended route based at least in part on the determined route segment safety scores; and

outputting the recommended route.

18 . The computer program product of claim 17 , wherein the speed distribution includes (i) speeds of vehicles in a first sub-group of vehicles travelling through a first location in a route segment and (ii) speeds of vehicles in a second sub-group of vehicles travelling through a second location in the route segment.

19 . The computer program product of claim 17 , wherein the computer instructions further include determining the plurality of route segments that together form an associated route.

20 . The computer program product of claim 19 , wherein the computer instructions further include determining a route safety score based at least in part on route segment safety scores for each route segment forming the route.
