US 2026/0290153 A1 · HIGH SPEED DETERMINATION OF INTERSECTION TRAVERSAL WITHOUT ROAD DATA

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.

Dependent claims

A computer-implemented method, comprising:

obtaining, by one or more processors, telematics data, associated with a vehicle trip of a vehicle, that is captured within an area associated with an intersection;
generating, by the one or more processors, a curve representing the telematics data associated with the vehicle trip that is captured within the area associated with the intersection;
comparing, by the one or more processors, the curve representing the telematics data associated with the vehicle trip that is captured within the area associated with the intersection to a curve representing actual turns of other vehicles through a same intersection to:
(i) determine whether the vehicle turned through the intersection, and
(ii) determine whether the vehicle made another turn near the intersection without passing through the intersection;
and
based on determining that the vehicle turned through the intersection, comparing, by the one or more processors, the telematics data associated with the vehicle trip that is captured within the area associated with the intersection to telematics data associated with the actual turns of the other vehicles through the same intersection.
