VEHICLE ROUTE CALCULATION
First Claim
1. A system for determining a most likely actual route traveled by a fleet vehicle based on historical vehicle status data received from the fleet vehicle at a plurality of time instances, the system comprising:
- a computer system comprising computer hardware programmed to implement a vehicle route calculation module configured to at least;
generate a vehicle management user interface;
output the vehicle management user interface for presentation to a user, the vehicle management user interface comprising a virtual road map;
receive a selection by a user of a vehicle in a vehicle fleet from the vehicle management user interface;
receive a selection by a user of a time period of travel of the vehicle from the vehicle management user interface for the purposes of calculating an estimated actual route traveled by the vehicle over the time period;
in response to receiving the selection of the vehicle and the time period of travel;
obtain vehicle status information corresponding to telematics data received from the vehicle at a plurality of time instances within the time period of travel, the telematics data comprising vehicle position data, andobtain map information comprising road data corresponding to the vehicle position data;
identify estimated vehicle position locations on roads identified from the road data at the plurality of time instances by comparing characteristics of the vehicle status information with the road data;
calculate an estimated actual route traveled by the fleet vehicle between the vehicle position locations; and
output a representation of the estimated actual route traveled by the vehicle for presentation on the virtual road map.

Abstract
This disclosure describes vehicle route calculation methods including “fitting” route segments between locations reported by a vehicle at different times along a route to create an overall “fitted” route. In certain embodiments, a vehicle management system generates a vehicle management user interface that displays the “fitted” route overlaid on a map. The “fitted” route can provide more useful tracking information to an administrator compared to simply displaying direct routes between known route stops.

6. Non-transitory physical computer storage comprising instructions stored thereon for implementing, in one or more processors, a method of calculating an estimated actual route traveled by a fleet vehicle based on historical vehicle status data at a plurality of time instances, the method comprising:
-
receiving a user selection of a fleet vehicle and a time period of travel of the fleet vehicle; in response to receiving the user selection, obtaining vehicle status data over the time period for the fleet vehicle, the vehicle status data being based on telematics data received from the fleet vehicle; obtaining map data based on the obtained vehicle status data, the map data comprising road information; identifying estimated vehicle position locations at a plurality of time instances on roads identified from the road information by comparing characteristics of the vehicle status data with the road information; and calculating an estimated actual route traveled by the fleet vehicle between the vehicle position locations, wherein the estimated actual route tracks road segments identified from the road information. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

- 16. A vehicle route highlighting user interface for facilitating calculation and display of historical route information for one or more fleet vehicles, the user interface comprising a map portion configured to display calculated routes of the one or more fleet vehicles represented on a road map of an area traveled by the one or more fleet vehicles, wherein the calculated routes track road segments of the road map identified based upon a comparison of characteristics of vehicle status information corresponding to telematics data received from in-vehicle devices of the one or more fleet vehicles with road data obtained from road map information, and wherein the map portion is configured to be generated by a computer system comprising computer hardware.
