Title:
渋滞予測装置及びその渋滞予測方法
Document Type and Number:
Japanese Patent JP6952516
Kind Code:
B2
Abstract:
To provide a congestion prediction device and a congestion prediction method therefor capable of suppressing a reduction in prediction accuracy related to congestion, and suppressing a processing load.SOLUTION: A congestion prediction device comprises: a detection part 51e for detecting a front vehicle on a passing lane with respect to a traveling lane of an own vehicle on the basis of image information from an on-vehicle camera; a first calculation part 51f for calculating an inter-vehicle to the detected front vehicle on the passing lane; a second calculation part 51g for calculating a speed of the front vehicle on the passing lane on the basis of a speed of the own vehicle and a change in the calculated inter-vehicle distance; a measurement part 51h for measuring time since the front vehicle on the passing lane is detected until a new front vehicle is detected on the passing lane; a traffic volume calculation part 51i for calculating a traffic volume on the passing lane on the basis of the speed of the front vehicle on the passing lane and the measured time; and a congestion prediction part 51j for predicting occurrence of congestion on the basis of the calculated traffic volume on the passing lane.SELECTED DRAWING: Figure 2
