# Travel and Travel Permissions in Warfront Nations

> Travel time, cost, and permission rules in Warfront Nations — Haversine distance, sea crossings, speed travel, and border requests.

## Travel Mechanics

Distance between regions uses the **Haversine formula** with Earth radius **6,371 km**. Base travel speed is **300 km/h**.

### Travel Time

```text theme={null}
time = (distance / 300) * 60   // minutes
time = time * 0.1              // base scaling

// Modifiers (multiplicative):
sea crossing : * 1.5
same state   : * 0.8
speed travel : * 0.5

time = round(time)             // nearest minute
```

### Travel Cost

| Mode          | Cost                         |
| ------------- | ---------------------------- |
| Normal travel | `round(distance * 1)` money  |
| Speed travel  | `round(distance * 0.5)` gold |

### Special Cases

* Your **first travel from Valhalla** (the private starter region) is **instant and free**.
* You **cannot start a new trip** while a current trip is in progress.

## Travel Permissions

Permission is **not** required when:

* Traveling within the same state
* Traveling to an **independent** region
* The destination state has **open borders**
* It's your first travel from Valhalla
* You are a state leader

Otherwise, you submit a request to the destination state's leader:

* **Approved** — you depart on the standard schedule
* **Rejected** — any travel cost paid is **refunded**

## Border Crossing Tax

Destination states can charge a **border crossing tax** (default 10%, capped at 50%) on inbound travelers, paid to the state treasury on top of base travel cost.
