IMPROVEMENTS IN SYSTEMS FOR INFORMING USERS ABOUT WAITING TIMES FOR BUSES AT NETWORK BUS STOPS

摘要

A system for informing bus network users about waiting times for buses at stops on the network. The system comprises means (3-6) for generating and transmitting electrical signals representing the distance (d) between each bus (1) and the next stop (2), and a unit provided at each stop for receiving said signals, selecting those which relate to the relevant stop, and displaying data relating to waiting times for approaching buses. Said system further comprises means for generating electrical signals representing two actual previous average bus speeds over two different periods immediately preceding the signal generation time, as well as means for processing said average speeds in order to determine the waiting times to be displayed.
