Package Exports

transportation

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (transportation) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

npm install transportation

Usage

var Transit = require('transportation')
var transit = new Transit()

// import GTFS data
transit.importGTFS('/path/to/gtfs/dir', function (err) {
  // have a look at the Transit instance
  console.log(transit)
})

transportation provides a replacement for node's console by using tconsole, so you can inspect the objects in the node.js REPL by using require('transportation/console'):

> var konsole = require('transportation/console')
> konsole(transit)

Command Line

npm install -g transportation

transportation provides a binary transportation. It supports the following commands.

Export Vehicles' Positions as GeoJSON

Prints all vehicles' positions of a specific date as GeoJSON linestrings with time components:

transportation positions /path/to/gtfs/dir

By default multiple trips are simply newline-separated GeoJSON to support streaming. If you want to return a single JSON array use the --array flag. Additional options are available via transportation positions --help. The generated GeoJSON LineString has its time property set as an array of timestamps and is therefore compatible with tools like LeafletPlayback and others.
