AarchCityRoads ver 3 (ACRv3) is a fully procedural, non-destructive & parametric City Roads Layout Generator, built entirely with Geometry Nodes, Blender 4.5.

ACRv3 is built to meet practical layout design requirements of Concept Design, Development & Visualisation for Architectural & Urban Design applications. It can also be useful for fields like Crowd & Traffic Simulations & GameDev.

ACRv3 generates a featured road layout from a 2D mesh, positioned at ground plane, treating mesh edges as center-lines for the roads. It adds essential design features like lane markings, central kerb/lines, pedestrian crossing & sidewalks alongwith light & traffic signal poles. It has option to add roundabouts. It also adds vehicles, trees, shrubs & peoples to aid design visualisation. Plots generated from the roads layout can be extracted for further design development. The 2D mesh can be generated directly in the viewport or via Geometry Nodes itself.

Prominent features & flexibilities of the Nodegroup include:

• Single-click switch between Right-Hand Drive (RHD) & Left-Hand Drive (LHD) Layouts.
• Set any Width for any Road.
• Set Lane nos. for each Road Width independently.
• Built-in algorithm to decide continuity of road at Interesections. Additional options to break continuity wherever required.
• Built-in option for Central Kerb & Lane Markings Extentions at Intersections.
• Set any width to any Sidewalk.Multiple options to set Sidewalk widths - individually & collectively.
• Options to set Plot Corners to sharp/rounded/bevelled - individually or collectively.
• Set any Turning Radius for any turn.Multiple options to set Turning Radius - individually & collectively.
• Provision to add Roundabouts.Built-in fuction to set Roundabout radius. Option to adjust Radius & Position subsequently.

ACRv3 comes with three built-in Display modes - Basic, Lite & Full - to assist with mesh & GN editing.

AVRv3 uses precise mathematical calculations for computing various parameters. It does not rely on Mesh>Volume>Mesh conversion or Proximity based approximations.
