METHOD AND DEVICE FOR DETERMINING TRAFFIC DENSITY USING ELECTRONIC CONTROLLER INSTALLED IN VEHICLE Russian patent published in 2018 - IPC G08G1/01 

FIELD: computing; counting.

SUBSTANCE: traffic density is estimated around a host vehicle moving on a roadway. Object detection system remotely senses and identifies the positions of nearby vehicles. Electronic controller predicts a path of a host vehicle, bins the nearby vehicles into a plurality of lanes including the host lane and one or more adjacent lanes flanking the predicted path, determines a host lane distance in response to a position of a farthest vehicle that is binned to the host lane, determines an adjacent lane distance in response to a difference between a closest position in an adjacent lane that is within the field of view and a position of a farthest vehicle binned to the adjacent lane, and indicates a traffic density in response to a ratio between a count of the binned vehicles and a sum of the distances. Device for determining traffic density in a vehicle and a device for monitoring the traffic density around a host vehicle are also disclosed.

EFFECT: determination of traffic density in real time from the interior of a moving host vehicle.
