Abstract

Various embodiments of the present invention are generally directed to a systems and methods for assessing turns made by one or more vehicles. According to various embodiments, the system is configured to identify, based telematics data captured from the vehicles, turns executed by the vehicle during a particular time period. The system is further configured to analyze the identified turns to determine and display various turn segment attributes to a user in order to provide an indication of turns having an abnormal or excessive duration and/or to provide overall efficiency-indicative information relating to the vehicle turns.

Claims

1. A system for assessing turns made by at least one vehicle, said system comprising:

one or more memory storage areas; and

one or more processors in communication with said one or more memory storage areas;

wherein said processors are, collectively, configured to;

receive, from one or more vehicle telematics devices located on the at least one vehicle, vehicle telematics data indicative of a travel path of the vehicle during one or more time periods, wherein the vehicle telematics data comprises a plurality of telematics data points, each telematics data point comprising data indicative of a vehicle heading at a particular location along the travel path of the vehicle and a time the data point is generated;

identify, based at least in part on said vehicle telematics data, one or more turns executed by the vehicle during the one or more time periods, the one or more turns each comprising instances in which the vehicle executes a turn in order to change from (i) traveling in a first roadway direction on a first road to (ii) traveling on a second road or traveling in a second roadway direction on the first road, wherein the one or more turns are each identified as comprising a change in vehicle heading between successive telematics data points of the plurality of telematics data points exceeding a predefined threshold heading value;

determine for each identified turn a turn segment comprising;

a beginning turn point comprising a telematics data point occurring before the successive telematics data points;

an ending turn point comprising a telematics data point occurring after the successive telematics data points;

the time elapsed between the beginning turn point and ending turn point, wherein the time elapsed defines the duration of the turn segment; and

an intersection type where the identified turn segment occurs by;

identifying, based at least in part on a telematics data point corresponding to the identified turn segment, a location of the turn segment;

comparing the location of the turn segment against map data to identify one or more roads intersecting at the location of the turn segment; and

determining, based at least in part on the one or more roads intersecting at the location of the turn segment, an intersection type for the turn segment;

receive a user request for analysis of turns corresponding to one or more identified intersection types;

identify, based at least in part on telematics data corresponding to each turn segment, those turn segments occurring at one of the identified intersection types; and

generate, based on said identified turn segments, a graphical display comprising a map illustrating the location of the identified turn segments and displaying one or more turn segment attributes of said identified turn segments.

2. The system of claim 1, wherein the beginning turn point is associated with a time and vehicle location at which the vehicle began executing a respective turn and the ending turn point is associated with a time and vehicle location at which the vehicle completed executing the respective turn.

3. The system of claim 1, wherein the processors are configured to determine for each turn segment the time of the turn segment'"'"'s occurrence, the location of the turn segment'"'"'s occurrence, and the duration of the turn segment, and to store each turn segment in association with data indicating the time of the turn segment'"'"'s occurrence, the location of the turn segment'"'"'s occurrence, and the duration of the turn segment.

4. The system of claim 3, wherein said processors are configured to determine the direction of each turn segment and classify each turn segment as representing a right turn, left turn, or turn-around turn accordingly.

5. The system of claim 1, wherein said processors are configured to identify, among the turn segments, outlier turn segments having a duration exceeding a threshold duration.

6. The system of claim 1, wherein said graphical display comprises a list of one or more of said identified turn segments.

7. The system of claim 6, wherein said list of one or more of said identified turn segments includes an data indicating one or more turn segment attributes selected from the group consisting of:

turn segment duration, turn segment type, turn segment location, and turn segment chronological number.

8. The system of claim 6, wherein said list of one or more of said identified turn segments is sorted according to turn segment duration.

9. The system of claim 6, wherein said list of one or more of said identified turn segments is sorted chronologically in order of turn segment occurrence.

10. The system of claim 6, wherein the processors are configured to identify those of said identified turn segments representing left turns and wherein said list of one or more of said identified turn segments comprises only said identified turn segments representing left turns and is sorted according to the duration of said identified turn segments representing left turns.

11. The system of claim 1, wherein the processors are configured to determine the average duration of the identified turn segments and wherein said one or more turn segment attributes comprise said determined average duration of the identified turn segments.
