There are too many different road marking styles in the world, and we are only iteratively adding support for less common ones.
When editing roads, there is no way to show turning lanes as a texture on the ground, nor is there any way to show bicycl lanes.
Not sure we will support the lane symbols directly or as an additional vector painting layer. Remains to be seen what we can do with the next format upgrade and a change in how individual road types are handled. Also applies to stop sign lines.
I have tried everthing to mimic a median turning lane, but it is trouble some, and I would like to see it soon on the road tools.
Yeah it's not so common here in Europe, and current road format structure doesn't have any space for median lanes, or in fact median anything (point 4), even though various forms of median strips other than a double line can be occasionally found here. Coincidentally we are currently working on defining the next iteration of the road system and formats, and this can be added into road profiles.
The format is being extended to allow handling:
- sidewalks
- parking lanes
- generated features along the road, like guard rails, markers, poles ...
- padding
- roads that generate tunnels, bridges, overpasses
- wear
The editor will be also a bit different, with separate road profiles and styles, some things like road surface type or lane and border width set to a constant value in profile.
