More road types and decorations#448

I would love more options for decorating roads and making different areas feel more unique and specialised

Some ideas:

• Lane markings and arrows
• Yellow road markings
• Stop/give-way signs
• Traffic lights
• Street signs
• Parking/loading markings
• Road barriers
• Bus stops
• More billboard options
• Different asphalt/gravel/dirt road types

I love transitioning from black roads in the city to dirt roads in forestry/mining areas, so having more road types would make it much easier to create natural-looking transitions between different parts of town.

More small road decorations would also make cities feel much more lived-in
