### v4.2.5-09526 (Vanilla-Cleaned Parking Definitions) ###

**Stripped parking_trailer.sii I cannot get it to work**

* Vanilla Traffic Compliance: Stripped all obsolete, modded, or non-native vehicle strings from all 85 parking and gate sections, ensuring the package exclusively utilizes standard American Truck Simulator base assets.

* Category Structure Preservation: Maintained all 85 functional distribution zones—including commercial depots, agricultural lots, industrial facilities, and roadside rest areas—without altering underlying hierarchy arrays or category bindings.

* Optimized Day/Night Spawn Weight Balance: Adjusted operational probability weights between daylight hours and nighttime intervals (such as peak night multipliers of 2.0 for rest stops and 1.8 for rural entries) to accurately simulate real-world logistics parking behavior.

* Lighting and Flare Standards: Enforced consistent forced_flare_low_beam: true properties across all night-specific spawn definitions and preserved functional warning light flags (forced_flare_hooter: true) for emergency and enforcement fleets.

* Engine Performance Optimization: Maintained clean low-poly and high-poly separation across independent day and night profile loops to eliminate transition-hour calculation overlaps and safeguard frame rates around dense asset prefabs.

### v4.2.4-09526 (Complete Fleet Release 1-85)

**Bug Fixes & Stability**

* parked_vehicle.sii, parked_trailer.sii and animated_gates.sii

* Removed legacy Featan parked_vehicle module to resolve fatal SCS namespace collisions and outdated base-game stub conflicts. It will still throw an error in game.log its an scs issue!

* Fixed the SiiNunit parser crash caused by duplicate suv.always.parked.physics unit registrations.

* Deleted the conflicting trailer.parked.groceries block to prevent game engine halts and allow clean vanilla fallbacks.

**Fleet & Traffic Integration**

* Complete Fleet Release (1-85): SUV, Pickup, and F-150 spawn pools are now handled entirely within the core SGSB architecture.

* Rebalanced base SUV physics spawns to a 1.5 day / 0.8 night probability weight for better lot density.

* Separated and stripped trailer configurations into a modular parked_trailer.sii file to ensure clean load orders without overwriting truck behaviors.

**Performance Optimizations**

* Low-Poly LOD Enforcement: Strict low_poly_only: true rules applied across parked trailer and vehicle configurations to improve rendering performance at a distance.

* Dynamic Spawn Curves: Implemented realistic day and night probability curves across all logistical hubs, rest stops, and service garages to dynamically clear lots and prevent memory bloat during off-peak hours.

### v4.2.3.1-09426 (Hotfix)###

**Back to 48 categories**

* I got to fancy with car and truck calls reverted alot. State specific calls to ambulance police and fire still there

v4.2.2-09326 - Smart Gates, Dynamic Parking and Safety Buffers (SGSB)

  Comprehensive Depot & Fleet Audit: Re-evaluated and mapped vehicle-to-trailer allocations across all 48 specialized operational sections, aligning spawn logic with realistic logistics hubs (including agricultural co-ops, oilfield extraction, marine port authorities, and intermodal container yards).

  Lighting & Night-State Standardization: Implemented uniform forced_flare_low_beam parameters and auxiliary hooter flags (forced_flare_hooter) across night-time municipal, emergency, and commercial parked profiles to prevent unlit vehicle spawns during dark cycles.

  Probability & Performance Tuning: Adjusted day/night spawn weightings (probability_day and probability_night) and optimized low_poly_only / always_visible tags across high-density zones like truck stops, rest areas, and dealership lots to balance visual immersion and game performance.

  Expanded Specialized Fleets: Integrated fine-grained support for regional service vehicles, including updated Department of Transportation (DOT) utility arrays, Maintenance of Way (MoW) railroad trucks, federal forest service patrols, and multi-axle heavy dumper/lowboy configurations.

  AI Fallback & Driver Flag Refinements: Streamlined individual AI fallback blocks (ai.*) to ensure robust compatibility with base game and traffic pack expansions, while validating correct driver: true and rear_align assignments for delivery and recovery units.

v4.2-82826

Updated the official mod title to Smart Gates, Dynamic Parking and Safety Buffers (SGSB), fully purging legacy toll references to focus exclusively on automated gates, dynamic yards, and roadside safety configurations.

Bumped project version to v4.2 (Major Fleet & Physics Optimization Release).

Massive Industry & Prefab Expansion (Sections 10–48)

Added 39 granular, sector-specific configuration blocks to ensure pre-fabs spawn contextually accurate vehicle and trailer combinations:

Industrial & Supply Chains: Deployed dedicated pools for agriculture depots, construction yards, energy logistics, chemical transport, refrigerated cold chains, intermodal containers, and timber operations.

Municipal & Emergency: Built explicit spawn categories for fire and rescue, military defense, Department of Transportation (DOT) maintenance, border patrol, school buses, and heavy wreckers.

Roadside & Regional Outposts: Populated truck stop diners, scenic lookouts, boat ramps, RV campgrounds, scale houses, and farm co-op lots with fitting local traffic profiles.

Standardized individual AI fallback profiles in Section 49 to enforce lightweight mesh rendering.

Shift Probability Weights: Cleaned up to deterministic separation (active shift 1.5, inactive shift 0.0 or reduced nocturnal ratios).

Yard Trailers (Section 38): Tuned daytime weight to 1.6 and night to 0.6 with mandatory rear_align: true.

Lighting Flares: Standardized forced_flare_low_beam: true across all operational night-shift variants.

Performance & Low-Poly Architecture

Massively overhauled background and shift-based vehicle variants across all core sections by switching low_poly_only from false to true alongside always_visible: false, preventing VRAM spikes and stutter during heavy map mod loading.

4.1.4-82326 (Nighttime Fleet Density, AI Balance & Weight Stations)

NEW *Weight Station Probability bumped from 60% to 20% to be more realistic.*

AI Spawn Rebalance (Consumer Vehicles): Reduced the daytime and nighttime spawn probabilities for all Pickups and SUVs (suv, pickup, tt_pickup, f_150) from 3.7 down to 3.5 to slightly reduce civilian clutter in industrial zones.

AI Spawn Rebalance (Commercial Vehicles): Increased the daytime and nighttime spawn probabilities for Commercial Delivery Vans (van, van...box) from 1.0 up to 1.9 to boost the presence of local delivery traffic.

Environment Immersion (Truck Stops): Doubled the nighttime spawn probability for parked semi-truck fleets (truck_trlr.parked.physics.night and truck_trlr.cheap.parked.physics.night) from 0.55 to 1.1. Truck stops and rest areas will now feel significantly more packed and challenging to navigate during late-night hours.

Global Density Bump: Applied a clean 7% spawn weight multiplier across all vehicle classes to gently fill out empty background lots and scenic turnouts without model spam or duplication.

Broadened Time Windows: Replaced hard 0.0 drop-offs with low "bleed-over" probability values across day and night cycles, completely eliminating the sudden mass-extinction and pop-in effect during dawn and dusk transitions.

Municipal Night Shift Flipped: Reconfigured city sweepers and garbage trucks (Mack RD and standard units) to own the graveyard shift, driving up nighttime probabilities (0.85) while lowering daytime presence for peak realism.
