Information system for informing users of a public transport network about waiting times at stops in the network |
摘要 |
An information system for informing users of a bus network about waiting times for buses at stops in the network. The system includes a system for locating buses coupled to a central point which broadcasts said positions at successive instants theta to receivers adapted to calculate waiting times for the buses on the basis of their positions, which positions reach the receivers after a certain average length of "transit" time T. In order to ensure that calculated waiting times as are accurate as possible, the central computer point broadcasts to the receivers estimated positions that the buses are expected to occupy at instant theta+T.
