Road Network Settings

To access this screen:

This form allows you to maintain the road network needed by the Haulage Analysis or the Optimization option in DTS Blend.

A Road Network defines road segments between Nodes for haulage calculations. Use this screen to enter the segments and their travel conditions for Haulage Analysis and the Optimisation option in Blend.

A Node is a named connection point in the road network. A road segment is the link between Node 1 and Node 2.

An example of road network settings for a project

Activity steps:

  1. Display the Road Network screen.

  2. To add a road segment:

    1. In the grid, add a new row.

    2. In Node 1, enter the start Node name.

    3. In Node 2, enter the end Node name.

    4. In Distance, enter the road distance between the nodes.

      Note: If the segment represents a curved road, enter the distance along the road, not the straight-line distance.

    5. In Elevation, enter the elevation change between the nodes.

      Note: Use the same unit system as Distance.

    6. If trucks can travel in both directions on this segment, select Bidirectional.

    7. If a pantograph is available on this segment, select Pantograph.

    8. In Rolling Resistance, enter the rolling resistance coefficient for the segment.

      Tip: Use the project standard value if you do not have a site value. The default is typically 3%.

    9. In Entry Angle [degrees], enter the segment entry angle at Node 1.

    10. In Exit Angle [degrees], enter the segment exit angle at Node 2.

    11. If you want to set fixed travel times, enter values in the applicable travel time fields:

      • T12 Empty and T12 Full for travel from Node 1 to Node 2.

      • T21 Empty and T21 Full for travel from Node 2 to Node 1.

      Note: Enter 0 to let the system estimate travel time.

    12. If you need to limit speed on the segment, enter:

      • Max Speed 12 for travel from Node 1 to Node 2.

      • Max Speed 21 for travel from Node 2 to Node 1.

    13. If the segment has signs at the exits, set:

      • Sign at Exit 1 for the sign when leaving the segment at Node 1.

      • Sign at Exit 2 for the sign when leaving the segment at Node 2.

  3. You can create groups of table rows by adding unique values into the Group field.

  4. Click OK to update your project.

  5. Save your project.
