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. |
