PROBLEM TO BE SOLVED: To provide a traveling partition line recognition device in which stability of recognition suppression of traveling partition line in disorderly road environment unsuitable for recognition of the traveling partition line is compatible with response incident to sudden change of road environment.SOLUTION: A traveling partition line recognition device includes calculation means for calculating the disorderliness of a camera image having impact on the recognition of traveling partition line of a road, learning means for updating the disorder learning value based on the disorderliness calculated this time by the calculation means, and the disorder learning value that is the learning value of disorderliness in the past, suppression means for suppressing recognition of the traveling partition line when the disorder learning value updated by the learning means exceeds a threshold, determination means for determining whether or not the environment of road is before and after change, and learning reset means for returning the disorder learning value to the previous value, if the determination means determines that the environment is before and after change.SELECTED DRAWING: Figure 1
