Interchange

This project is the first (and only) fully-automated installer for TheTransitClock, designed to make launching it as easy and effortless as possible. See Why

Usage

Pre-Setup

  • Download the latest version of Ubuntu or Debian
  • Install Docker: curl -sSL https://get.docker.com/ | sh
  • Install Git
  • Download Interchange: git clone https://github.com/cscape/interchange.git
  • Navigate to the Interchange directory: cd interchange

Interchange Setup

In the agencies directory, you'll find an example of how to configure transit agencies to work in Interchange. The name of the files don't matter, but they must end in .env so the installer knows what to look for.

Each configuration file corresponds to 1 transit agency. Each one must have an ID (without spaces), a link to a GTFS feed, and a link to a GTFS Realtime Vehicle Positions feed. Each one must be double quoted as follows. Here's an example of a configuration file:

ID="tampa-regional-transit"
GTFS="http://www.gohart.org/google/google_transit.zip"
GTFSRT="http://api.tampa.onebusaway.org:8088/vehicle-positions"

Running Interchange

. go.sh

The start script will build an Interchange container (may take up to 20 minutes), start the PostgreSQL database, create database tables for each transit agency, load the gtfs data into the database, create an API key, and deploy the API + Web service.

The API is available at http://localhost:3020/api
The Web interface is at http://localhost:3020/web

Why?

TheTransitClock is a big workhorse that basically turns vehicle positions (AVL/GPS data) into trip updates for transit agencies. This is extremely useful for generating arrival times at stops and metro stations, and critical for having realtime data on Google Maps. The problem is that TheTransitClock is confusing to set up. After about 3 months of trial-and-error, and 4 variations of Wayline Interchange, this is the final result that works. So far, it's worked very well and this is now a breeze to use.
