If the diversion route markers (Road Closures & Diversions layer) were either underneath the live traffic layer, or made transparent, so the live traffic layer can be seen & not obscured, it would make managing the network easier, enabling us to see the impact of certain roadworks on it
one.network data layers always lay on top of live traffic, so we will not be able to implement this.
We do have plans to improve the UI for our restriction geometries - to offset the diversion/closures, making sure the closure lines lay on the correct side of the road. This should help with visualisation.
