Abstract
Abstract A transportation information system is disclosed, having a transportation terminal that transmits a transportation information request with a Dedicated Short Range Communication (DSRC) method, receives a transportation information reply corresponding to the transportation information request with the DSRC method, and provides the transportation information reply to a transportation subscriber. An Advanced Traveler Information Service (ATIS) terminal transmits a traveler information request with the DSRC method, receives a traveler information reply corresponding to the traveler information request with the DSRC method, and provides the traveler information reply to an ATIS subscriber. A base station communicates with the transportation terminal and the ATIS terminal through a two way DSRC communication. A transportation server classifies packets transmitted from the base station, through a dedicated network, by destination, performs a transportation service, and performs an ATIS service by interlocking with an ATIS server.
