Cityliner

Create colorful visualizations of public transport from GTFS (General Transit Feed Specification) public transport datasets. Public transport routes drawn on a map, where the thickness and opacity of the lines is determined by the frequency of the schedules along that route segment. Each primary mode of transportation, as defined in GTFS terms, is represented by a unique color.

Features

• Visualize GTFS routes based on their frequency and route types.
• Renders result as a PDF.
• Multiple color schemes: default, pastel, inferno, earthy, cool.
• Water body visualization (beta).
• Administrative borders (beta).

Installation and Setup

1. Clone this repository:

   git clone [email protected]:dragoon/cityliner.git
   cd cityliner

2. Install required dependencies:

   pip install -r requirements.txt

3. Download Ocean shape file from OpenStreetMap: https://osmdata.openstreetmap.de/data/water-polygons.html (WGS84 Projection) and unzip it into the oceans directory.
4. Download GTFS data with shapes.txt file available, see catalog here: https://github.com/MobilityData/mobility-database-catalogs. And place it under gtfs/[place-name]/**
5. Download some city/transport company logos if needed and place into assets/logos/[place-name]/**.

Usage

Run the script using the following command:

python main.py --gtfs gtfs/[place-name] --center [center_coordinates] --poster [other_options]

Options:

• --gtfs: Path to the GTFS directory. (Required)
• --processed-dir: Path to the directory with intermediate files (defaults to ./processed).
• --center: Coordinates of the center in the format latitude,longitude. (Required)
• --max-dist: Maximum distance from the center on y-axis (in km). Default is 20 km.
• --width: Width of the output drawing (in px).
• --height: Height of the output drawing (in px)
• --poster: Create a drawing for A0 poster size.
• --water: Plot water bodies (beta).
• --admin-borders: Plot administrative borders of the city/region determined by the center coordinates (beta).
• --color-scheme: Choose a color scheme for the poster. Allowed values are: default, pastel, inferno, earthy, cool. Default is default.
• --logos: List of logos for the poster (inside ./assets/logos/{place-name}/)

(Either --width and --height or --poster must be provided)

Example Helsinki:

python main.py --gtfs=./gtfs/helsinki --place-name=helsinki --center=60.1706017,24.9414482 --poster --color-scheme=pastel --water --logos "helsinki.svg" "hsl.svg"

This project is inspired by Michael Mueller's gtfs-visualizations project, implemented with Node.js and Processing, and my fork: https://github.com/dragoon/gtfs-visualizations, which allowed to process large GTFS files, added actual poster-generation code, and a possibility to restrict the visualization area within a certain radius, among other improvements.

This implementation has been developed from scratch with Python, ReportLab for PDF rendering, different color palettes, and a possibility to visualize water bodies using OpenSteetMap data, among other changes.
