<p><P>PROBLEM TO BE SOLVED: To maintain safety even when the number of terminals on vehicles is increased by giving priority to the terminal on the vehicle with high risk in allotting communication resources in a radio communication method in which communication between road and the vehicle and the communication between the vehicles are shared. <P>SOLUTION: The radio communication method in a vehicle communication system carries out multiplexed communication by having vehicle loaded terminals and roadside machines and uses one radio transmission path. The method includes: a process in which the vehicle loaded terminal acquires information on its own vehicle; a process in which the vehicle loaded terminal calculates the degree of risk expressing the degree of risk of the own vehicle on the basis of the acquired information on its own vehicle; a process in which the vehicle loaded terminal notifies the calculated degree of risk to the roadside machine; and a process in which the roadside machine allots the communication resources by giving priority to the vehicle loaded terminal for the vehicle with the high degree of risk. It is preferable to have the calculation for the degree of risk calculated also based on information regarding notified surrounding vehicles. As the information of the vehicles, it is preferable to have behavior of the vehicle, operation of the vehicle and a state of a driver included. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
