To provide a vehicle travel locus transmission system and a vehicle traffic control system that reduce a communication load between a control device and each vehicle, a data processing load by the control device, and a data storage capacity.SOLUTION: In a vehicle travel locus transmission system comprising a GNSS receiver 17, a vehicle-side transmitter/receiver 18, a locator calculation unit 13, a wheel speed sensor 15, a gyro sensor 16, an acceleration sensor 14, and the like, the locator calculation device 13 transmits a first linear coordinate Ln together with vehicle identification information ID from the vehicle-side transmitter/receiver 18 to an external device 100 when an angle θ formed by the latest first linear coordinate Ln with respect to an extension line of a second linear coordinate Ln-1 one cycle before exceeds a predetermined threshold value, while the latest first linear coordinate Ln connects a latest first position coordinate Pn acquired at each predetermined cycle and a second position coordinate Pn-1 one cycle before.SELECTED DRAWING: Figure 6
【課題】 管制装置と各車両との通信負荷および、管制装置によるデータ処理負荷、データ保存容量を削減する車両の走行軌跡送信システムおよび車両の交通管制システムの提供。【解決手段】 GNSS受信機17、車両側送受信機18、ロケータ演算装置13、車輪速センサ15、ジャイロセンサ16、加速度センサ14などを備えた車両の走行軌跡送信システムであって、ロケータ演算装置13は、所定の周期毎に取得した最新の第1の位置座標Pnと一周期前の第2の位置座標Pn-1を結ぶ最新の第1の直線座標Lnが一周期前の第2の直線座標Ln-1の延長線に対するなす角θが所定の閾値を超過したとき、車両側送受信機18から外部装置100に車両識別情報IDと共に第1の直線座標Lnを送信する。【選択図】図6
