Reverse running detecting device and reverse running detecting method

摘要

PROBLEM TO BE SOLVED: To improve the detection accuracy of a reverse running vehicle based on the output from a sensor of a vehicle detector when the vehicle travels on a road where the lane change of the running vehicle is allowed. A processor (23) of a reverse running detection device (11) outputs a vehicle detection signal based on an output from sensors (S1 to S4) that detect a traveling vehicle (3) in each lane in a plurality of lanes (2A, 2B). And a configuration for determining whether or not there is a reverse vehicle traveling in the opposite direction in at least one lane of the plurality of lanes 2A and 2B based on the detection patterns regarding one or more traveling vehicles in the vehicle detection signals. To do. [Selection diagram] Fig. 1
