Claim 4:
5. A map generation system, comprising:
a vehicle including a terminal, the terminal including a communication unit configured to communicate through a network; and
one or more server apparatuses provided in one or more base stations for mobile phone, each of the one or more server apparatuses being configured to:
communicate with the communication unit of the terminal every 10 msec to 300 msec to receive data held by the terminal;
accumulate the data held by the terminal, the data held by the terminal including data regarding the vehicle, and a surrounding vehicle,
create current state map data using data accumulated, map data, and regional data, the regional data including data regarding a location of the vehicle, the current state map data comprising a speed of the vehicle, a location of the surrounding vehicle and a speed of the surrounding vehicle,
make predictive calculation of a forward region of the vehicle, using the location of the vehicle, the speed of the vehicle, the location of the surrounding vehicle and the speed of the surrounding vehicle in the current state map data, so as to determine whether the vehicle and the surrounding vehicle interfere with each other in a future time,
communicate with the communication unit regarding a result of the predictive calculation, wherein:
change the speed of the vehicle when the vehicle and the surrounding vehicle interfere with each other in the future time based on the result of the predictive calculation,
hold server time and a server identification, and
in communicating with the communication unit regarding the result of the predictive calculation, the server time and the server identification are transmitted together with the result of the predictive calculation.
