Primary issues for maintaining the road network
- Remove unneeded junction nodes (those not at intersections, or separating segments with different properties, i.e. city-name, street name, elevation, allowed U-turns, or splitting a segment which is over 10km long).
- Remove excess geometry nodes (those which are not changing the geometry of a segment). When the geometry node is very near the end of a segmsegment double check while zoomed-in to see if the geometry node is actually changing the turn angle.
- Inspect and correct connectivity of necessary junctions.
- Update the road network "Street Types" to match FC, for more information see FC update info
- Update all segment "Street Names" in accordance with the guidelines in the Road Names (USA) wiki article.
- Inspect and correct overpasses/underpasses to ensure that the segments are on different levels, and do not have a junction node where they meet.
- Ensure that any roads crossing at the same elevation level have a junction node connecting them.
