1. A construction-related information estimation system comprising:
- a moving body correspondence information terminal that is configured to move together with a moving body that moves on a target road, the target road being a road on which a construction site that is a place which is estimated to be under a construction is located or a road that is located near the construction site, and transmit terminal information including a terminal ID signal that is its own identification information and its own position information; and
an information processing device configured to have map information including information on the construction site and the target road and receive the terminal ID signal and the position information transmitted from the moving body correspondence information terminal,wherein the information processing device is configured to estimate a current situation of the target road based on the terminal information and the map information acquired from the moving body correspondence information terminal, andthe construction-related information estimation system, further comprising;
a beacon installed in the construction site, and including a transmission unit that transmits radio waves including a beacon ID signal that is its own identification information and a reference intensity signal indicating a radio wave intensity; and
a plurality of distance estimation information terminals configured to receive radio waves transmitted by the beacon together with the beacon ID signal and the reference intensity signal, calculate an estimated distance that is a distance between the beacon corresponding to the beacon ID signal and the distance estimation information terminal based on an actual intensity of the received radio waves and the reference intensity signal, and transmit radio waves together with the terminal ID signal that is its own identification information, its own position information, the beacon ID signal, and the estimated distance,wherein the information processing device is configured toreceive the terminal ID signal, a plurality of pieces of position information, the beacon ID signal, and a plurality of estimated distances transmitted by the distance estimation information terminals together,obtain the estimated position that is a position of the beacon based on the estimated distances and the pieces of position information transmitted by the distance estimation information terminals, andspecify the estimated position as the construction site.
