Abstract: A trajectory analysis device extracting a trajectory of movement of a moving object by using results of detection by one or more sensors disposed in an environment where the moving object exists, is provided. The device includes a storage and a controller. The storage stores: partial trajectory data indicative of a plurality of partial trajectories extracted in advance from the results of detection; connection parameter information indicative of a connection condition for connecting the partial trajectories to each other; and partial area data defining each of a plurality of partial areas. The controller connects two partial trajectories each belonging to any of the plurality of partial areas, based on the connection parameter information, to extract a trajectory of the moving object for each of the partial areas. The connection parameter information is set for each of the partial areas.
