At Road Width, try to add taper road to the most outest carriage way ( in this case, it is “carriageway 3”):
- Click on the + sign
- Change the ID to carriageway 3, change the number of row to 4. Then click “Add”, then click “OK”
This is how you can create taper road.
- Now your carriageway 3 is divided into 4 section with equal-spacing chainage. So you can easily vary the width according to chainage position.
