PROBLEM TO BE SOLVED: To accurately notify an operator of up to which degree a moving vehicle approaches a specific section, and of to which degree of a distance exists up to going out to the outside from its constant section, after arriving at the constant section.SOLUTION: Snow throw work support processing means 25 calculates a section approach distance d1 up to a snow throw prohibiting section from a position coordinate of a snowplow 3 by the position coordinate of the snowplow 3 successively acquired from a GNSS receiver 14 installed in the snowplow 3 and information on the snow throw prohibiting section stored in storage means 23, and displays a section approach distance d1 on display means 22 installed in the snowplow 3 when this section approach distance d1 becomes a constant value or less, and afterwards, calculates a section escape distance d2 until the position coordinate of the snowplow 3 goes out to the outside of the snow throw prohibiting section when the position coordinate of the snowplow 3 arrives at the snow throw prohibiting section, and displays the section escape distance d2 on the display means 22.

    【課題】移動中の車両が特定の区間にどの程度にまで近づき、また一定の区間に到達した後で、その一定の区間から外に出るまでどの程度の距離があるのかを、オペレータに正確に通知する。【解決手段】投雪作業支援処理手段25は、除雪車3に設置したGNSS受信機14から逐次取得した除雪車3の位置座標と、記憶手段23に記憶された投雪禁止区間の情報とにより、除雪車3の位置座標から投雪禁止区間までの区間接近距離d1を算出し、この区間接近距離d1が一定値以下になると、除雪車3に設置した表示手段22に区間接近距離d1を表示させる。その後、除雪車3の位置座標が投雪禁止区間に到達すると、除雪車3の位置座標が投雪禁止区間の外に出るまでの区間脱出距離d2を算出し、表示手段22に区間脱出距離d2を表示させる。【選択図】図2
