is a data storage section in the data processor 8 that accumulates operation results, and #24 displayed in this data storage section 9 is the data number of the latest operation information received.

データ処理手段８，９は、このようにデータ処
理機８とデータ記憶部９とから構成されている。 The data processing means 8 and 9 are thus composed of the data processor 8 and the data storage section 9.

以下に上記実施例の動作について説明する。 The operation of the above embodiment will be explained below.

１車両（XYZ）は地点を通過したとき車上記
憶部４に一連のデータ番号＃30までの運行情報
を蓄積していたとする。1. Assume that the vehicle (XYZ) had stored a series of operation information up to data number #30 in the on-board storage unit 4 when it passed the point.

この車両が地点Ｂを通過するとき車上通信手
段１はデータ番号＃30の運行情報を路上通信機
５Ｂに送信する。 When this vehicle passes point B, the on-board communication means 1 transmits operation information with data number #30 to the roadside communication device 5B.

２このとき、データ処理機８は車両（XYZ）
については、既にデータ番号＃24まで正しく受
信していたとする。2 At this time, the data processor 8
Assume that up to data number #24 has already been correctly received.

ここにデータ番号＃30の運行情報が路上通信
機５Ｂから伝送されてくるので、データ処理機
８ではデータ番号が飛んだことからデータ欠損
が発生したことが判明する。 Since the operation information with data number #30 is transmitted from the roadside communication device 5B, the data processing device 8 knows that data loss has occurred since the data number has skipped.

３そこでデータ処理機８は車両（XYZ）が欠
に通過するであろう地点Ｃの路上通信機５Ｃに
対して、予め車番（XYZ）と要求するデータ
番号＃25の運行情報を送る。3. Then, the data processor 8 sends the vehicle number (XYZ) and the requested data number #25 in advance to the roadside communication device 5C at the point C where the vehicle (XYZ) will pass without fail.

４車両（XYZ）が地点Ｃに到行すると、まず
１回地点Ｃでの運行情報の交信が行なわれる
が、次に路上通信機５Ｃから、車上通信手段１
に対してデータ番号＃25から送出する様に要求
命令が出される。4 When the vehicle (XYZ) arrives at point C, the operation information at point C is exchanged once, and then from the on-road communication device 5C to the on-board communication means 1.
A request command is issued to send data starting from data number #25.

５すると車両（XYZ）はデータ番号25から順
次運行情報を送り出す。5 Then, the vehicle (XYZ) sends operation information sequentially starting from data number 25.

６この情報が地点Ｃだけ送りきれなかつた場
