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.

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: Techniques for using vehicle telematics data for high speed determination of intersection traversals are provided. Telematics data from a vehicle trip may be obtained and compared to an area associated with an intersection to attempt to isolate telematics data points that are within the intersection. A simplified line generated based on the isolated telematics data points is then compared to vector lines representing entrances and exits of the intersection to attempt to identify an intersection entrance and exit from the vehicle trip. The simplified line is then compared to an average simplified line representing trips of other vehicles through the same entrance and exit of the same intersection to determine whether the vehicle turned through the intersection. If it is determined that the vehicle turned through the intersection, the telematics data associated with the vehicle trip may be compared to telematics data associated with other vehicle trips through the intersection.

Abstract: Techniques for collapse of driving data to determine spatial averages of vehicle paths determining a spatial average vehicle path through a turn of within an intersection from a plurality of vehicles are provided. The telematics data may include plurality of spatial data points for each respective vehicle trip. Spatial data points associated with the turn of interest from each respective vehicle may be isolated and ordered chronologically, and converted into respective lines. A number of equally spaced points may be placed along each respective line, and a number of geometric median points may be determined by averaging each of the points along each of the respective lines. An average simplified line representing the spatial average vehicle path through the turn of the intersection may be generated based on the number of geometric median points.

The template is a collection of the text blocks that are commonly included in each of the documents of the subset.
