To make it possible to appropriately control or assist vehicle driving without requiring a roadside sensor.SOLUTION: A traffic communication method executed by a wireless roadside machine 200 for road-to-vehicle communication comprises: a step S1 of periodically broadcasting a notification message for notifying a presence of the wireless roadside machine 200 in a first transmission system; a step S2 of receiving a vehicle information message including information of a vehicle 100 from the vehicle 100 which has received the notification message; a step S3 of generating a traffic control message for instructing or assisting vehicle driving based on the vehicle information message; and a step S4 of broadcasting the traffic control message in a second transmission system. The first transmission system is a transmission system with higher error resistance than the second transmission system.SELECTED DRAWING: Figure 7
【課題】路側センサを必要とすることなく車両運転の制御又は支援を適切に行うことを可能とする。【解決手段】路車間通信を行う無線路側機200が実行する交通通信方法は、無線路側機200の存在を通知するための通知メッセージを第1伝送方式で周期的にブロードキャストするステップS1と、通知メッセージを受信した車両100から、当該車両100の情報を含む車両情報メッセージを受信するステップS2と、車両情報メッセージに基づいて、車両運転を指示又は支援するための交通管制メッセージを生成するステップS3と、交通管制メッセージを第2伝送方式でブロードキャストするステップS4とを有する。第1伝送方式は、第2伝送方式に比べて誤り耐性が高い伝送方式である。【選択図】図7
