An activatable barrier has a barrier body that can be moved between a first position and at least one second position. An actuation device is configured for moving the barrier body from the first position into one or the other of the second positions. A control device, which is connected to the actuation device, is configured to control the actuation device as a function of a control signal for moving the barrier body. The barrier body, in the first position, is recessed into a delimitation of a space, through which a flow of people is guided. In the at least one second position, the barrier body projects from the delimitation, so that the flow of people is redirected or braked by the barrier. |
