A second acquirer acquires, when the first vehicle is traveling on the first road toward the intersection and the second vehicle is traveling on the second road toward the intersection, riskiness of the intersection from a second storage unit storing the riskiness of each of multiple intersections. Based on the traveling tendency of the first vehicle and the riskiness of the intersection, a judgment unit judges whether or not there is caution information at the time of passing through the intersection. ## Claims ### Claim 1 An information processing device comprising: a processor configured to acquire a traveling tendency of a first vehicle from a first storage unit configured to store the traveling tendency at an intersection of each of a plurality of vehicles in advance of the processor acquiring the traveling tendency of the first vehicle; and a transmitter configured to transmit, based on the traveling tendency of the first vehicle, a caution information to a second vehicle, wherein the first vehicle and the second vehicle are traveling toward an intersection such that the first vehicle and the second vehicle intersect each other, the transmitter is configured to transmit the caution information before the second vehicle enters the intersection, the processor is configured to acquire vehicle information at a time of entering an intersection of each of a plurality of vehicles, and the processor is configured to derive, based on the vehicle information of each of a plurality of vehicles, the traveling tendency at an intersection of each vehicle and riskiness of each intersection to store in the first storage unit and a second storage unit respectively. ### Claim 2 (depends on 1) The information processing device of claim 1, wherein the caution information includes riskiness at a time of entering the intersection judged based on the traveling tendency of the first vehicle. ### Claim 3 (depends on 2) The information processing device of claim 2, wherein the riskiness at the time of entering the intersection is judged to be higher when the traveling tendency of the first vehicle indicates a tendency to contravene traffic regulations. ### Claim 4 (depends on 1) The information processing device of claim 1, wherein the processor is configured to acquire riskiness of the intersection from a second storage unit configured to store the riskiness of each of a plurality of intersections in advance of the processor acquiring the riskiness of the intersection, and the transmitter is configured to transmit the caution information based on the traveling tendency of the first vehicle and the riskiness of the intersection. ### Claim 5 (depends on 4) The information processing device of claim 4, wherein the caution information includes riskiness at a time of entering the intersection judged based on the riskiness of the intersection. ### Claim 6 (depends on 5) The information processing device of claim 5, wherein the riskiness at the time of entering the intersection is judged to be higher when the riskiness of the intersection is higher. ### Claim 7 An information processing method, executed by an information processor, the method comprising: storing a traveling tendency at an intersection of each of a plurality of vehicles in a first storage unit; acquiring a traveling tendency of a first vehicle from the first storage unit; transmitting, based on the traveling tendency of the first vehicle, a caution information to a second vehicle, acquiring vehicle information at a time of entering an intersection of each of a plurality of vehicles, and deriving, based on the vehicle information of each of a plurality of vehicles, the traveling tendency at an intersection of each vehicle and riskiness of each intersection to store in the first storage unit and a second storage unit respectively, wherein the first vehicle and the second vehicle are traveling toward an intersection such that the first vehicle and the second vehicle intersect each other, and the caution information is transmitted before the second vehicle enters the intersection. ### Claim 8 (depends on 7) The information processing method of claim 7, wherein the caution information includes riskiness at a time of entering the intersection judged based on the traveling tendency of the first vehicle. ### Claim 9 (depends on 8) The information processing method of claim 8, wherein the riskiness at the time of entering the intersection is judged to be higher when the traveling tendency of the first vehicle indicates a tendency to contravene traffic regulations. ### Claim 10 (depends on 7) The information processing method of claim 7, further comprising: acquiring riskiness of the intersection from a second storage unit configured to store the riskiness of each of a plurality of intersections, and transmitting the caution information based on the traveling tendency of the first vehicle and the riskiness of the intersection. ### Claim 11 (depends on 10) The information processing method of claim 10, wherein the caution information includes riskiness at a time of entering the intersection judged based on the riskiness of the intersection. ### Claim 12 (depends on 11) The information processing method of claim 11, wherein the riskiness at the time of entering the intersection is judged to be higher when the riskiness of the intersection is higher. ### Claim 13 A vehicle system comprising: a first storage unit configured to store a traveling tendency at an intersection of each of a plurality of vehicles; a processor configured to acquire the traveling tendency of a first vehicle from the first storage unit; and a transmitter configured to transmit, based on the traveling tendency of the first vehicle, a caution information to a second vehicle, wherein the first vehicle and the second vehicle are traveling toward an intersection such that the first vehicle and the second vehicle intersect each other, the transmitter is configured to transmit the caution information before the second vehicle enters the intersection, and the vehicle system further comprises a second storage unit, wherein the processor is configured to acquire vehicle information at a time of entering an intersection of each of a plurality of vehicles, and derive, based on the vehicle information of each of a plurality of vehicles, the traveling tendency at an intersection of each vehicle and riskiness of each intersection to store in the first storage unit and the second storage unit respectively. ### Claim 14 (depends on 13) The vehicle system of claim 13, wherein the caution information includes riskiness at a time of entering the intersection judged based on the traveling tendency of the first vehicle. ### Claim 15 (depends on 14) The vehicle system of claim 14, wherein the riskiness at the time of entering the intersection is judged to be higher when the traveling tendency of the first vehicle indicates a tendency to contravene traffic regulations. ### Claim 16 (depends on 13) The vehicle system of claim 13, further comprising: a second storage unit configured to store riskiness of each of a plurality of intersections, wherein the processor is configured to acquire the riskiness of the intersection from the second storage unit, and the transmitter is configured to transmit the caution information based on the traveling tendency of the first vehicle and the riskiness of the intersection. ### Claim 17 (depends on 16) The vehicle system of claim 16, wherein the caution information includes riskiness at a time of entering the intersection judged based on the riskiness of the intersection.
