The base station 200 includes a controller 22 and a communicator 21. The controller 22 is configured to acquire weather condition information indicating a weather condition on the road, and to estimate a risk level of occurrence of a traffic accident on the road based on the weather condition information. The communicator 21 is configured to transmit, to a vehicle 100 on the road, a warning message including information based on the risk level estimated. ## Claims ### Claim 1 A base station installed around a road, the base station comprising: a controller configured to acquire weather condition information indicating a weather condition on the road, and to estimate a risk level of occurrence of a traffic accident on the road based on the weather condition information; and a communicator configured to transmit, to a vehicle on the road, a warning message including information based on the risk level estimated, wherein the weather condition information includes insolation direction information indicating a direction of insolation to the vehicle on the road, and the controller is configured to estimate the risk level based on the insolation direction information. ### Claim 2 (depends on 1) The base station according to claim 1, wherein the weather condition information includes weather phenomenon information indicating a condition of a weather phenomenon on the road, the controller is configured to estimate the risk level based on the weather phenomenon information, and the weather phenomenon includes at least one of rain, fog, or air pollution. ### Claim 3 (depends on 1) The base station according to claim 1, wherein the controller is configured to estimate the risk level further based on intersection information indicating whether the base station is installed around an intersection. ### Claim 4 (depends on 3) The base station according to claim 3, wherein the controller is configured to estimate a third risk level as the risk level in a case where the base station is not installed around the intersection, and estimate, as the risk level, a fourth risk level higher than the third risk level in a case where the base station is installed around the intersection. ### Claim 5 (depends on 1) A traffic communication system comprising: a vehicle; and the base station according to claim 1. ### Claim 6 A base station installed around a road, the base station comprising: a controller configured to acquire weather condition information indicating a weather condition on the road, and to estimate a risk level of occurrence of a traffic accident on the road based on the weather condition information; and a communicator configured to transmit, to a vehicle on the road, a warning message including information based on the risk level estimated, wherein the weather condition information includes insolation direction information indicating a direction of insolation to the vehicle on the road, the controller is configured to estimate the risk level based on the insolation direction information, the communicator is configured to receive a notification message from the vehicle on the road, and the controller is configured to estimate a first risk level as the risk level in a case where a movement direction of the vehicle on the road identified based on the notification message and the direction of insolation are not opposite to each other, and estimate, as the risk level, a second risk level higher than the first risk level in a case where the movement direction and the direction of insolation are opposite to each other. ### Claim 7 (depends on 6) A traffic communication system comprising: a vehicle; and the base station according to claim 6. ### Claim 8 (depends on 6) The base station according to claim 6, wherein the weather condition information includes weather phenomenon information indicating a condition of a weather phenomenon on the road, the controller is configured to estimate the risk level based on the weather phenomenon information, and the weather phenomenon includes at least one of rain, fog, or air pollution. ### Claim 9 (depends on 6) The base station according to claim 6, wherein the controller is configured to estimate the risk level further based on intersection information indicating whether the base station is installed around an intersection. ### Claim 10 (depends on 9) The base station according to claim 9, wherein the controller is configured to estimate a third risk level as the risk level in a case where the base station is not installed around the intersection, and estimate, as the risk level, a fourth risk level higher than the third risk level in a case where the base station is installed around the intersection. ### Claim 11 A base station installed around a road, the base station comprising: a controller configured to acquire weather condition information indicating a weather condition on the road, and to estimate a risk level of occurrence of a traffic accident on the road based on the weather condition information; a communicator configured to transmit, to a vehicle on the road, a warning message including information based on the risk level estimated; and an interface connected to a plurality of sensors for sensing a mobile body on the road, wherein the plurality of sensors includes an infrared camera, and the controller is configured to select the infrared camera among the plurality of sensors based on the weather condition information, and to estimate the risk level further based on a captured image obtained by the infrared camera. ### Claim 12 (depends on 11) A traffic communication system comprising: a vehicle; and the base station according to claim 11. ### Claim 13 (depends on 11) The base station according to claim 11, wherein the weather condition information includes weather phenomenon information indicating a condition of a weather phenomenon on the road, the controller is configured to estimate the risk level based on the weather phenomenon information, and the weather phenomenon includes at least one of rain, fog, or air pollution. ### Claim 14 (depends on 11) The base station according to claim 11, wherein the controller is configured to estimate the risk level further based on intersection information indicating whether the base station is installed around an intersection. ### Claim 15 (depends on 14) The base station according to claim 14, wherein the controller is configured to estimate a third risk level as the risk level in a case where the base station is not installed around the intersection, and estimate, as the risk level, a fourth risk level higher than the third risk level in a case where the base station is installed around the intersection. ### Claim 16 A traffic communication method used in a base station installed around a road, the traffic communication method comprising: acquiring weather condition information indicating a weather condition on the road; estimating a risk level of occurrence of a traffic accident on the road based on the weather condition information; and transmitting, to a vehicle on the road, a warning message including information based on the risk level estimated, wherein the weather condition information includes insolation direction information indicating a direction of insolation to the vehicle on the road, and estimating the risk level based on the insolation direction information.
