    Abstract: Example methods, apparatus, and articles of manufacture to capture and compress telematics data are disclosed herein. An example computer-implemented method, executed by a processor, to represent telematics data includes identifying, with the processor, a physical intersection of roads, identifying, with the processor, virtual lines crossing the roads, assigning, with the processor, ordinals to the virtual lines, representing, with the processor, a physical traversal through the physical intersection captured in first telematics data by a pair of the ordinals, and storing the pair of the ordinals in second compressed telematics data.

    Abstract: An example method includes obtaining raw telematics data from a vehicle trip; comparing bounding boxes associated with respective intersections to the raw telematics data points from the vehicle trip in order to isolate points that are within bounding boxes associated with intersections and validating that the raw telematics data points within a bounding box associated with an intersection are associated with an actual traversal of the intersection by comparing a line created by combining the raw telematics data points within the bounding box to a spatial average line for other trips through the intersection. For each intersection, an a determining, for each intersection, an average acceleration of the portion of the vehicle trip through the intersection may be compared to the average acceleration of trips through the intersection by other vehicles in order to determine a measure of safety associated with the portion of the vehicle trip through the intersection.

    Abstract: Techniques for determining a direction that a vehicle turned through an intersection using vehicle telematics data associated with the vehicle are provided. A first simplified line representative of the vehicle trip may be generated using the telematics data and may be compared to a boundary of a region associated with the intersection to identify spatial data points and times associated with the vehicle's entrance to and exit from the region associated with the intersection. A second simplified line representative of the portion of the vehicle trip through the intersection may be generated based on the identified spatial data points and times, and the second simplified line may be substringed into two segments. Angles associated with the first (entrance) segment and second (exit) segment may be measured, and a direction associated with the vehicle's turn through the intersection during the vehicle trip may be identified based on the angles.

    Abstract: Example methods, apparatus, and articles of manufacture to compress telematics data are disclosed herein. An example computer-implemented method includes identifying, using one or more processors, a portion of recorded telematics data representing a physical transversal of a physical intersection of two or more road segments, wherein each road segment has an assigned unique ordinal value; identifying, using one or more processors, a first road segment on which the physical transversal entered the intersection; identifying, using one or more processors, a second road segment on which the physical transversal exited the intersection; identifying, using one or more processors, a pair of ordinal values including a first ordinal value assigned to the first road segment, and a second ordinal value assigned to the second road segment; and storing the pair of ordinal values instead of the portion of the recorded telematics data in a compressed representation of the recorded telematics data.
