Construction road route design device, construction road route design method, and recording medium

A construction road route design method comprising:

• acquiring topography data indicating a current topography of a construction site;
• acquiring topography data indicating a design topography of a construction site;
• acquiring a plurality of two or more road ends that serves as a start point and an end point of a construction road;
• and
• selecting nodes existing between the plurality of road ends, calculating, for a plurality of routes that goes through the selected nodes and leads to the plurality of road ends, costs based on construction soil amounts of the construction road from topography data of the current topography and the design topography, and, by selecting a route that minimizes a calculated cost, searching for a route between the plurality of road ends.

A non-transitory computer-readable recording medium storing a program, the program causing a computer to:

• acquire topography data indicating a current topography of a construction site;
• acquire topography data indicating a design topography of a construction site;
• acquire a plurality of two or more road ends that serves as a start point and an end point of a construction road;
• and
• select nodes existing between the plurality of road ends, calculate, for a plurality of routes that goes through the selected nodes and leads to the plurality of road ends, costs based on construction soil amounts of the construction road from topography data of the current topography and the design topography, and, by selecting a route that minimizes a calculated cost, search for a route between the plurality of road ends.
