A trajectory analysis device that displays relevant information on a trajectory of a moving object, comprising: a display interface to display the relevant information; a storage to store trajectory data indicating a plurality of trajectories and the relevant information; an input interface to receive input by a user operation; and a controller to control the display interface based on the relevant information and the user operation input on the input interface, wherein the controller causes the display interface to display one or more staying locations where trajectories stay, based on the trajectory data, receives an input result by a user operation selecting at least one of the staying locations, receives an input result by a user operation designating a designated location different from the selected staying location, and extracts the relevant information to be displayed on the display interface, based on the selected staying location and the designated location.
