The centralized monitor device 8 calculates the red/green time ratio of a signal arranged at an intersection according to the mean speed information and supplies it to a judgement device 9. The judgement device 9 generates signal control information for changing the signal in the timing where each vehicle passes and stops safely according to the red/green time ratio and speed information of vehicles to enter the intersection, and supplies the information to a signal controller 10.  The signal controller 10 changes the signal in the timing based upon the received signal control information.
