<P>PROBLEM TO BE SOLVED: To provide a mobile communication device and a method for determining a time-difference system traffic signal which determine whether a traffic signal is a time-difference system traffic signal based on traffic signal information which does not include traffic signal attribute information. <P>SOLUTION: A mobile communication device installed in a moving body comprises: a communication unit for receiving information including signal display at a predetermined time point in a traffic signal corresponding to routes and/or information which can determine a time until when the traffic signal corresponding to routes changes the signal display at the predetermined time point to next signal display; and a control unit which, in one traffic signal and another traffic signal installed opposite to the traffic signal in the same intersection, determines at least the traffic signal as a time-difference system traffic signal when signal display of the traffic signal at a predetermined time point is different from signal display of the other traffic signal, or when a time until when the traffic signal changes the signal display at the predetermined time point to next signal display is different from a time until when the other traffic signal changes the signal display to next signal display. <P>COPYRIGHT: (C)2013,JPO&INPIT |
