Roundabout Converter

Adds a Roundabout Converter tool under Roads > Tools. Click a crossroads or T-junction and a settings window opens with a live ghost of the roundabout. Press Build and the junction is rebuilt as a roundabout, connected to the existing roads. Settings - Presets: Mini, Standard and Large, or set it yourself. - Radius (12 to 50 m) and ring lanes (1, 2 or 4; 3 with Roads Plus). - Shape: round, oval along the main road, or oval turned. - Ring road look: plain, trees, barriers, bus lane or tram tracks, where the road type has them. - Centre island: none, grass, trees, fountain or paved. Towns don't build inside it. - Pedestrian crossings on or off. - Tram line straight through the centre, with a button to choose which pair of roads it joins. Editing Click an existing roundabout to Remove it (back to a plain junction) or Edit it (back to a junction, then change the settings and build again). Good to know - The ghost shows the cost; Build is disabled when you can't afford it. - Old-style (cobbled) junctions get an old-style ring. - Left-hand traffic maps get a clockwise ring. - Rings on hillsides are laid on a tilted plane, and the window warns when the slope is steep. - Buildings along the replaced road sections are lost (the window shows how many). To keep them, split the roads with the road tool close to the junction first, then convert. - Removing the mod keeps your roundabouts, as they are ordinary roads; the centre islands may disappear. Supports Roads Plus (3-lane and old-style one-way rings). Uses the base game's roads, textures, models and roundabout icon (Urban Games).
