ABSTRACT:
A control section (212) adds first time information from a clock (204) to road traffic information from a light beacon communication device to create road traffic information by first time for storing in a storage device (205). A time judging device (209) receives second time information from other mobile communication terminal and creates an information transmission instruction if the first time of the first time information is more up-to-date than the second time of the second time information. An information selecting section (211) selects and transmits a part of the road traffic information by first time based on other traveling direction information indicative of the traveling direction of other vehicle and traveling direction information from an azimuth finder (208). Upon receiving road traffic information by third time from other mobile communication terminal, the control section (212) overwrites the road traffic information by first time in the storage device (205).
