<P>PROBLEM TO BE SOLVED: To solve such a problem that, although a station staff generally give a warning to a user who is liable to be exposed to a danger due to an approaching vehicle such as a train, it is almost impossible for the station staff to cover all the dangers, and a measure is taken to prevent such an oversight by increasing the number of station staffs, however, it is still impossible to eliminate such an oversight completely. <P>SOLUTION: Information about a possible danger obtained as a result of retrieving a moving vehicle service database is made available through a portable electronic apparatus at a train station. Guide information about trains in motion can also be made available when a signal for requiring the guide information about trains in motion is transmitted from a portable electronic apparatus, and then, a calculator of the system receives the signal and responds to the requirement. <P>COPYRIGHT: (C)2012,JPO&INPIT |
