Indiana retail regular gasoline, current versus the AAA-reported aggregates one day, one week, one month, and one year ago.
Indiana's 9 standard economic regions. Each region's average uses ONLY AAA-real prices (the 15 metros AAA publishes) — predicted/modeled per-county prices are NOT mixed in. Cities outside an AAA-covered metro show a clearly-labeled PREDICTED price below — derived from the AAA-real metros within the same region and refreshed weekly with AAA.

Crude → refinery → pipeline → rack → retail. Live deltas from front-month futures and refiner equities.
Refresh cadence: every hour, on the top of the hour, via the TCG-Indiana-Gas-Refresh Windows scheduled task on the TCG server. Per-location prices come from AAA's Indiana state page; neighbor-state averages from each state's AAA page; oil/refining quotes from Yahoo Finance front-month futures and energy ETFs; news from EIA, IEA, DOE, OPEC, FERC, PHMSA, EPA, and IN.gov RSS feeds. The 3-day forecast is a transparent heuristic (not ML), and the AI summary is generated locally by Ollama (qwen2.5:7b-instruct).
Data freshness:
AAA metro-area averages for Indiana cities (Indianapolis, Fort Wayne, Evansville, South Bend, Gary, Lafayette) plus the statewide average. Updates every 30 minutes. Individual per-station prices (Marathon, Shell, BP, Speedway, etc.) are limited to stations currently reporting a retail price.
