Haul Road Manager

This command builds and links the haul road network, recognizing 3D polylines and adding them to the network. All possible roads must be drawn as 3D polylines in CAD, either draped onto the surface model, or snapped to contours. Individual layers can be used for clarity to see the roads in the manager by color and layer. There aren't any tagged segments to select the first time this command is run, so the preview image will be blank. The segments must be added by picking the green "+" button to bring them into the editor.

Preview Window Display: The upper preview window has four buttons for Pan, Zoom Realtime, Rotate and Zoom Extents.
Add Segments: Selecting the green "+" button will prompt for selecting the 3D polylines in CAD to add to the haul road network. This must be done initially if there are no segments found.
Remove Segment: This green "X" button will remove the highlighted segment from the manager.
Pick Segments: The Select from Screen, Pick Segments button is used to pick already named haul road segments, and add them to the manager. They must be already tagged with the Add Segments for them to be recognized.
Split at Grade Break: Selecting this button will split the haul roads into smaller segments, based on the percent grade tolerance so that each segment is within that slope tolerance. This isn't a requirement, but the idea is to have segments with constant grade as the truck speed is depended on the grade of the road, and this will divide the road into smaller segments if desired. This will also break the 3D polylines into the smaller segments, so it is recommended to Save the drawing as a new name before breaking, so that there is a back up to go back to if necessary. There are two dialogs that appear from this command. It will only break the highlighted segments, so it is easy to control which roads are being divided.
Delay Points: These are point symbols inserted into the drawing the will trigger a delay event for the specified number of minutes. Examples would be a stop sign at an intersection, or a one lane bridge where trucks have to stop. Any symbol from all of the libraries can be inserted to represent the location. These delays will be accounted for when the trucks pass over that spot.
AutoSet: The AutoSet Segment Parameters based on Grade option colors all the haul roads based on their perfile:///C:/Carlson%20Manual/manuals/Carlson2007/Surface_Mining/Reserves_Timing/Haul_Fleet_Manager/Haul_Truck_Manager.htmlcent slope. This is an option to graphically see the slope of each road, simply by the color it is drawn in. This will also change the color of the 3D polylines in the plan view. They will stay on their original layers, so they can be set back to color ByLayer if desired. The slope interval was set here to a 1 or 2%, starting at -5%, as an example. Notice in the image below, that the new colors are set by the percent slope of the road. These colors are now different than the initial image where they were colored by the layer.

Now that the haul roads are defined in the manager, they can be used in the haul road processing commands.
