Abstract
The reception unit receives the traffic light information at least a transition between first and second light colors of a traffic light at an intersection and turn-on times of the first and the second light colors, using a wireless signal received from a server via a transceiver. A position acquisition unit acquires a position of a vehicle. A passing speed range calculation unit calculates a speed range in which the vehicle is allowed to pass through the intersection in accordance with light colors of the traffic light, based on the traffic light information and on the position of the vehicle. The messaging unit outputs a message of driving assistance information including suggestions for deceleration or a passage possibility through the traffic intersection. A vehicle behavior storing unit stores content of the message and a behavior of the vehicle corresponding to the content of the message in a behavior memorizing unit.
