PROBLEM TO BE SOLVED: To prevent error communication with an on-vehicle device mounted on a vehicle traveling along adjacent lanes, with a simple configuration.SOLUTION: A roadside wireless device 10 acquires an identifier from an on-vehicle device mounted on a vehicle traveling along a first communication area 31 as a first identifier. In addition, from an external wireless device having an area different from the first communication area 31 defined as a second communication area 32, the roadside wireless device 10 acquires an identifier obtained from an on-vehicle device mounted on a vehicle traveling along the second communication area as a second identifier. Then, the roadside wireless device 10 determines whether or not to stop communication with the on-vehicle device mounted on the vehicle traveling along the first communication area 31, depending on whether or not the first identifier matches the second identifier.SELECTED DRAWING: Figure 1
【課題】簡便な構成により、隣接車線を通行する車両に搭載された車載器との誤通信を防止することを目的とする。【解決手段】路側無線装置10は、第1通信領域31を通行する車両に搭載された車載器から識別子を第1識別子として取得する。また、路側無線装置10は、第1通信領域31とは異なる領域を第2通信領域32をとする外部無線装置から、第2通信領域を通行する車両に搭載された車載器から取得された識別子を第2識別子として取得する。そして、路側無線装置10は、第1識別子と第2識別子とが一致するか否かに応じて、第1通信領域31を通行する車両に搭載された車載器との通信を打ち切るか否かを判定する。【選択図】図1
