GTFS-Ride

About GTFS-Ride

gtfs-ride is a command-line utility for creating GTFS-Ride formatted data. GTFS-Ride is a format for storing transit ridership data. It takes two inputs: a GTFS file and Automated Passenger Counter (APC) data and exports GTFS-Ride data.

gtfs-ride can import APC data in the following ways:

• From a local CSV file
• From a CSV file available at a URL
• From the Swiftly API

Supported APC data formats

Currently, gtfs-ride works for ridership data in the following APC data formats:

• GMV
• Swiftly
• Passio
• LTD
• RVTD
• WETA

The type of APC data format is auto-detected based on the field names in the APC data. If gtfs-ride can not detect the type, it will throw an error.

How it works

gtfs-ride allows you to specify which GTFS and APC data to use as command-line arguments or by using a JSON configuration file. An example of a configuration file is located in this repo as config-sample.json.

1. Run gtfs-ride command-line tool
2. Specify GTFS file and APC data covering the same time period using command-line arguments or via JSON configuration file.
3. gtfs-ride imports specified GTFS into SQLite using node-gtfs
4. gtfs-ride imports specified APC data into SQLite. The type of APC data is auto-detected.
5. Errors and issues while importing APC data are logged to a log.txt file included in the output folder.
6. Valid GTFS-Ride data is exported to the output folder.

Command Line Usage

Setup

• Install node.js https://nodejs.org/en/download/

• Install gtfs-ride globally directly from npm:

  npm install gtfs-ride -g

Updating

npm update gtfs-ride -g

Usage

See command-line options below for more information.

gtfs-ride --gtfsPath /path/to/gtfs --apcPath /path/to/apc/data.csv

or

gtfs-ride --configPath /path/to/your/custom-config.json

This will import APC and GTFS data from the paths specified and output a GTFS-Ride file.
