Abstract
The portable appliance informs users about waiting times at stops in a bus network, the appliance comprising a radio receiver to receive data enabling waiting times to be determined, an interrogation keypad, a central unit for evaluating the estimated time of arrival of the next bus at a particular stop, a screen for displaying the waiting time for said bus, and a sound emitter. The central unit is designed to update cyclically the estimated time of arrival for the next bus and to actuate the sound emitter when said estimated time of arrival differs excessively from the time of arrival initially estimated the last time the appliance was interrogated by the user.
