On the other hand, reliability isindispensable to handle the ticket that is the note. It proposes Decentralized algorithm of the fare calculationby IC card and an AFC gatethe faster the AFC gate processes the ticket, the poorer thereliability gets. In this thesis, it proposes the autonomousdecentralized processing technology to meet highspeed processingin wireless IC ticket system and the requirement of high reliability.

Therefore,the ticket system that has both highspeed processing and highreliability is necessary and indispensable. However, the highspeed processingand the high reliability are ambivalent at this system becauseof wireless communications between an IC card and the AFC to achieve highspeed processing. There is Processing speed improvement of the automatic farecollection gate AFC gate as one of the important problemsto correspond to the passengers getting on and off in high densitytransportation at the peak. Moreover,Autonomous, decentralized consistency technology in each subsystemis shown for highreliability. For the passengersconvenience improvement and maintenance reduction, wirelessIC card ticket system is hoped.

In addition, to make these theeffective one, Wireless communication area enhancing technologytouch & going method and Command system for the datahigh speed processing are shown. However, the highspeed processingand the high reliability are ambivalent at this system becauseof wireless communications between an IC card and the AFC to achieve highspeed processing. Moreover,Autonomous, decentralized consistency technology in each subsystemis shown for highreliability.
