Abstract
A portable appliance (1) is provided for informing the users of a bus network about waiting times for buses at various stops of the network. Simple depressions of keys (3, 4, 5) cause appropriate displays to appear on a screen (2) of the appliance, enable a plurality of bus driving distances approaching respective predetermined stops of the network to be stored, and simply pressing on a button (6 or 7) makes it possible to cause any stored driving distance to be selectively displayed on said screen, together with visible information concerning the waiting times for buses at the stop approached by the final driving distance.
