PROBLEM TO BE SOLVED: To provide a wrong-way driving prevention system capable of easily and properly calling attention to a wrong-way driving vehicle by using an existing road infrastructure.SOLUTION: The wrong-way driving prevention system includes: a vehicle-mounted device mounted on a vehicle; and a roadside unit capable of carrying out a two-way communication with the vehicle-mounted device. The roadside unit provides a piece of wrong-way running warning information that representing that the vehicle is running on a wrong-way, and a piece of down link information including a reproduction condition for reproducing the wrong-way running warning information to the vehicle-mounted device of the vehicle which is passing an area capable of communication of the roadside unit and wrong-way running warning information. When the reproduction conditions are satisfied, the vehicle-mounted device reproduces the wrong-way running warning information.SELECTED DRAWING: Figure 5
【課題】既存の道路インフラを利用して、逆走車両に対して容易かつ的確に注意喚起を行うことができる逆走防止システムを提供する。【解決手段】逆走防止システムは、車両に搭載される車載器と、車載器と双方向通信可能な路側機と、を備え、路側機は、当該路側機の通信可能エリアを通過する車両の車載器に対して、当該車両が逆走していることを示す逆走警告情報及び逆走警告情報を再生するための再生条件を含むダウンリンク情報を提供し、車載器は、再生条件が成立した場合に逆走警告情報を再生する。【選択図】図5
