CUESTA DE MIRANDA  v1.0.0
========================================

Cuesta de Miranda v1.0.0 - Downhill layout. RN 40, La Rioja, Argentina.

Los Tambillos to the Rio Miranda: the long climb to Bordo Atravesado, then down the north-face hairpins (28.1 km, point to point, A-B timing with a summit split).
Built from real elevation and survey data: the road follows the surveyed line and a fitted real profile (grades to 9.5 %), cut into Copernicus GLO-30 terrain with rock cuts, retaining walls and fills.
- 6.7 m two-lane road with 1 m shoulders, double yellow centre line, widened hairpins, banking
- W-beam guardrail, concrete parapets on the hairpins, concrete gutters on the curve insides
- The bridges over the creeks with piers and abutments, the Mirador lay-by on the summit hairpins
- Argentine warning and regulatory signs, RN 40 shields, kilometre posts, chevrons and delineators
- Red Patquia sandstone and grey granite rock, jarilla scrub and cardon cacti
- No street lighting, as on the real road: headlights, reflective signs and delineators at night
- Two layouts: Downhill (start Los Tambillos) and Uphill (start Rio Miranda), 8 pit boxes each

Where public sources stop (the exact sign positions, kilometre post numbers, barrier heights, the mirador layout), the track follows Argentine national standards (Ley 24.449 Anexo L, DNV manuals) and satellite imagery.
Works with the CSP Traffic Planner: data/traffic.json in each layout holds the traffic lane (right-hand traffic both ways, turning round on the paved areas at both ends).
AssettoServer AI traffic: each layout's ai/fast_lane.aip holds the same lane as one closed spline (up the pass on the right, round the end, back down on the right). Leave TwoWayTraffic OFF - both directions are already in the spline. Not yet tested on a live server: it should work, and it will be verified in a later version.
Needs Content Manager and Custom Shaders Patch 0.2.11 or newer (made on CSP 0.3.0-preview445).

Free to download and use. If this track is used on a paid server, in a paid pack or in any paid product, contact the creator first: 4mgarage - www.4mgarage.com

  AssettoServer: set EnableAi in extra_cfg.yml; the server reads the layout's ai/fast_lane.aip by itself.
