Visualize implicit turn restrictions

[!i!]

I suggest to enhance the plugin to visualize implicit turning restrictions with an icon, too.

For example: Road A is a oneway way, road B has a junction with A and so it's only allowed to leaf road B following the direction of oneway road A.

This will avoid double and misunderstanding restrictions and allow us to see more possible errors that might confuse routers.

Why not instead let validator warn if a turn restriction is redundant?

That might be another good idea. But there is still the pro that you can visually check against your memories if the router assumes a restriction where nothing is.

It is entirely depending on direction of traffic flow, as positive or negative direction is allowed vehicles to move. When there is both way traffic direction is allowed then it would apply.
