User Guide: Add Manual Connecting Point

The Add Manual Connecting Point feature helps improve the road platform generation by manually placing key points at intersections and junctions. This prevents issues like misalignment, overlapping, and gaps between earthwork (EW) and road platforms. It also enables better road platform generation especially at the junctions. The idea is that we insert “connection points” along an appropriate position on the road platform line, so that other platforms can be better connect to it, as shown below:

Users can enable this option when needed to ensure accurate platform connections at the junction particularly in complex projects.

When to Use Add Manual Connecting Point feature? #

You should enable this feature in the following situations:

• Gaps between road and EW platforms – When adjacent platforms do not connect seamlessly, causing unwanted gaps
• Overlapping platforms – When different platform sections overlap due to rounding errors

Enabling Add Manual Connecting Point #

To activate this feature, follow these steps:

1. Open the project in MiTS
2. Navigate to Options > Project Settings > Road > Kernel
3. Locate the option Add Manual Connecting Point
4. Enable the option

Types of Manually Placed Points #

Depending on the issue encountered, different types of manual points can be added:

AddJunctionPointFromOpposite #

• Used when road intersections cause overlapping
• Adds a new point at the junction to ensure proper connection

AddJunctionPointFromMinor #

• Used when minor roads do not align properly with major roads
• Places three new points at the left, right, and center of the junction

AddRoadPointFromOpposite #

• Used when the starting/ending points of minor roads are different
• Adds a point at the junction’s right side to align both ends correctly

AddOuterItemFirstPoint & AddOuterItemLastPoint #

• Used when the number of offset items (carriageway, shoulder, etc.) differs between major and minor roads
• Ensures smooth platform transitions by adding connection points at the first or last segment

Best Practices #

• Test before finalizing – Enable the feature and check results in the model layout
• Adjust pixel size settings – Lowering pixel size may reduce misalignment but can introduce rounding errors
• Combine with auto-fix options – Use the overlapping auto-fix option if necessary

Troubleshooting #

If issues persist after enabling Add Manual Connecting Point, consider:

• Checking if road and EW platforms have consistent settings
• Adjusting vertical and horizontal alignment parameters
• Re-evaluating the pixel size setting for road platforms

Conclusion #

The Add Manual Connecting Point feature provides precise control over platform alignment, ensuring clean connection between road, junction, and EW platforms. Using it effectively minimizes alignment errors and enhances overall project accuracy.
