To provide a traffic volume estimation device capable of accurately estimating traffic volumes based on remote sensing and data from connected cars.SOLUTION: A traffic volume estimation device includes: an overall traffic volume measurement unit 320 that pre-detects the number of all vehicles in a predetermined area based on remote sensing by analyzing satellite images; a partial traffic volume measurement unit 322 that pre-detects the number of connected vehicles in the predetermined area based on location information obtained from connected vehicles capable of V2X communication; and a traffic volume estimation unit 326 that estimates a traffic volume in an arbitrary area based on a CA ratio which is a ratio of the number of connected vehicles pre-detected in the predetermined area with respect to the number of all vehicles pre-detected in the predetermined area, and the number of connected vehicles in the arbitrary area near the predetermined area that is newly detected by the partial traffic volume measurement unit 322.SELECTED DRAWING: Figure 4
