## Installing

```shell

npm install vbb-routing

```

## Usage

```js

todo

```

## Segment model

Starting to walk the graph, our first segment looks like this:

```js

const first = {

	// edge info

	where: 'center', // arrival node

	when: 1554307600, // start time

	route: null, // we just started, so no route ID

	duration: 0, // we just started, so edge duration

	// current state

	transfers: 0,

	blacklist: ['center'], // node we don't want to visit again

	previousSegment: null

}

```

A follow-up segment (the result of a single edge in the graph) may then look like this:

```js

const second = {

	// edge info

	where: 'lake',

	when: 1554308040 + 360, // arrival time

	route: 'B',

	duration: 360,

	// current state

	transfers: first.transfers + 0,

	blacklist: first.blacklist.concat('lake'),

	previousSegment: first

}

```
