Why constant-radius curves look better

Freehand curves drift: the road gets wider on one side, then narrows, and the eye picks it up immediately. This generator measures each block's distance from a single centre point and keeps the blocks whose distance falls inside the road band and inside the angle you asked for. Because every block is measured from the same centre, the inside and outside edges stay exactly parallel.

Laying it out in game

  1. Place a temporary marker at the centre of the turn — everything is measured from it.
  2. Mark the two straight roads the curve has to join.
  3. Lay the kerb ring first; it is the hardest line to correct later.
  4. Fill the road surface between the kerbs.
  5. Remove the centre marker and add lamps or fences on the kerb.

Radius rules of thumb

  • Garden path: 5–10 blocks.
  • Village street: 12–20 blocks.
  • Highway or rail sweep: 30–60 blocks.
