Learning Lanes From Vehicle Probes

摘要

Systems, methods, and apparatuses are disclosed for determining lane information of a roadway segment from vehicle probe data. Probe data is received from vehicle camera sensors at a road segment, wherein the probe data includes lane marking data on the road segment. Lane markings are identified, to the extent present, for the left and right boundaries of the lane of travel as well as the adjacent lane boundaries to the left and right of the lane of travel. The identified lane markings are coded, wherein solid lane lines, dashed lane lines, and unidentified or non-existing lane lines are differentiated. The coded lane markings are compiled in a database. A number of lanes are predicted at the road segment from the database of coded lane markings.

主权项

1. A method comprising:
receiving, using a processor, probe data from vehicle camera sensors from a plurality of vehicles at a road segment, the probe data comprising lane marking data for the road segment; identifying, from the probe data for each vehicle of the plurality of vehicles, any lane markings present for: (1) a left boundary of a lane of travel, (2) a right boundary of the lane of travel, (3) a left boundary of an adjacent lane to the left of the lane of travel, and (4) a right boundary of an adjacent lane to the right of the lane of travel; coding the identified lane markings, wherein solid lane lines, dashed lane lines, and unidentified or non-existing lane lines are differentiated; compiling the coded lane markings from the plurality of vehicles at the road segment in a database; and predicting a number of lanes at the road segment from the coded lane markings.
