Empty Path

You use the Empty path tab to define the path of the haulage route that the trucks travel, and the speed at which they travel, when they are not loaded. You use the Segments data grid to define the segments path. You use the Velocities data grid to define the speed at which the trucks travel. The speed you define for the first segment of the path is applied to all segments, until a different speed is defined. You can also define changes in speed at specified lengths along the segments.

The Empty path tab of the Segments data grid includes the Reverse Full Path icon. When you click Reverse Full Path, the Segments and Velocities data grids are filled using the lines defined in the Full path tab, but with the lines listed in reverse order.

Columns in the Segments Data Grid

When you use the Insert option for the Segments data grid, a row is added to the grid filled with the Segment name of a segment that connects to the previous segment. You can use the drop-down list for the Segment name cell to select any other segment that connects to the previous segment. You cannot add successive segments that are not connected.

Column	Description
Segment name	The name of the segments that make up the haulage path.
Length	The length of the segment.
Total length	The total length of all segments added to the haulage path.

Columns in the Velocities Data Grid

You can define a change in velocity at any distance along a segment on an empty haulage path.

Tip: You can use the spreadsheet view to assign velocities to the haulage routes. When you open the temporary spreadsheet view, a window opens listing each point in the segments that make up the empty path, as well as any points required to define a change in velocity that is specified in the Velocities data grid. You can use formulas in the spreadsheet view to assign velocities to the points more efficiently. When you close the spreadsheet view, a row is created in the Velocities data grid for each position at which the velocity changes on the empty path.

Column	Description
Segment name	The name of the segment for which the velocity is being defined.
Distance	The distance along the segment after which you want the velocity to change.
Total distance	The total distance from the first point of the first segment that makes up the empty path to the position at which this change in velocity takes effect.
Velocity	The velocity that unloaded trucks can travel after the distance specified along the segment. Note: This velocity is effective until a change in velocity is defined, or until the end of the path.
