To prepare a suitable earth-quantity allocation plan.SOLUTION: An earth-quantity allocation plan preparing section generates cut-earth and mound areas from three-dimensional landform data and three-dimensional design data of a planning region and extracts a mound block 4B' that is executable and greatest in mound height out of the mound areas. Also, the earth-quantity allocation plan preparing section extracts cut-earth blocks 4C1-4C3 that are executable and greatest in cut-earth height, in respective ones of a plurality of cut-earth areas adjacent to the mound areas including the mound block 4B'. Then, the earth-quantity allocation plan preparing section sets a cut-earth block of a transport source of cut-earth from the extracted cut-earth blocks 4C1-4C3 based on a transportation condition (e.g., a transportation distance).SELECTED DRAWING: Figure 7 【課題】適切な土量配分計画を作成する。【解決手段】土量配分計画作成部は、計画領域の三次元地形データと三次元設計データとから、切土エリアと盛土エリアを生成し、盛土エリアのうち、施工可能で最も盛土高が大きい盛土ブロック４Ｂ'を抽出する。また、土量配分計画作成部は、盛土ブロック４Ｂ'を含む盛土エリアに隣接する複数の切土エリアそれぞれにおいて、施工可能で最も切土高が大きい切土ブロック４Ｃ１～４Ｃ３を抽出する。そして、土量配分計画作成部は、運搬条件（例えば運搬距離）に基づいて、抽出した切土ブロック４Ｃ１～４Ｃ３から切土の搬送元の切土ブロックを設定する。【選択図】図７
