An ATOS-PDA system for train operation information offered through cellular networks

We have developed a new information system to provide our station staff with personal digital assistants (PDAs) with updated train-operation information in the Tokyo metropolitan and suburban area. So far one of the most important problems to be solved in our company, JR East, Japan, is how early we could provide our passengers on platforms with precise train-operation status in case of emergency. Offering our passengers the precise real-time information is necessary when a train accident occurs, since we are operating a lot of trains at two-minute headway in some lines in the rush hours. But now our station staff can easily and promptly offer the precise train-operation information to our passengers by the PDAs through cellular networks.
