Exact published match
Airport, Charlotte Amalie, and configured point-to-point routes show their table value automatically, including the lower per-person group fare when applicable.
Published fares first.
Estimates clearly labeled.
STT GO automatically prices routes that appear in the configured St. Thomas tariff table. For a GPS pickup or an unlisted pairing, the platform prepares a planning estimate for a licensed driver or dispatcher to verify. Custom estimates never go directly to payment.

GPS area analysis
The phone’s coordinates are compared with mapped tariff anchors using Haversine distance. The closest area guides the planning estimate; it is not treated as a legal tariff boundary.
Human verification
A custom total is prefilled in the approval desk. Only a licensed driver or dispatcher can confirm it, and the rider reviews that confirmed total before Stripe checkout.
The old fallback was improved.
The previous rule used 55% of the cheaper airport/town anchor sum. Testing it against 21 known direct routes showed a consistent upward bias. Segment-specific calibration improved the known-route error:
| Rider segment | Old MAE | New MAE | New average bias |
|---|---|---|---|
| 1 rider | $3.62 | $3.14 | +$0.19 |
| 2+ riders · per person | $2.52 | $2.10 | −$0.29 |
Distance helps identify the right area.
Straight-line miles are used to find the nearest mapped tariff anchor—not to operate a taximeter. Actual road travel is longer on St. Thomas.
| Example pair | Straight-line miles |
|---|---|
| Airport Terminal → Charlotte Amalie (Town) | 2.8 |
| Charlotte Amalie (Town) → Havensight (Crossroad) | 1.0 |
| Red Hook → Sapphire Beach | 0.5 |
| Charlotte Amalie (Town) → Red Hook | 5.4 |
RATE FRESHNESS
What is verified—and what still needs a primary document.
Cross-check completed: representative airport, town, and direct-route values were compared with current 2026 public fare guides. The Mahogany Run server-side value was corrected to match the current table used by the rider calculator.
Certification gap: the current Virgin Islands Taxicab Commission tariff card was not available as a machine-readable public document during this review. The posted lawful tariff and Commission guidance control if any source differs.
