TransitFlow
A tool that animates scheduled transit frequency using Transitland API data and Processing for visualizations.
What is TransitFlow?
TransitFlow is a tool that animates scheduled transit frequency by downloading data from the Transitland API and creating visualizations using Processing with Unfolding Maps. It generates animated maps showing transit vehicle movements throughout a day, helping visualize public transportation patterns and flows in cities worldwide.
Urban planners, data journalists, transit enthusiasts, and researchers interested in visualizing public transportation systems and understanding transit frequency patterns.
Developers choose TransitFlow because it provides a straightforward way to create professional-quality transit animations with minimal setup, leveraging the comprehensive Transitland dataset and the powerful visualization capabilities of Processing.
Overview
Animating scheduled transit trips using the Transitland API and Processing
Use Cases
Best For
- Creating animated visualizations of transit system frequency
- Exploring public transportation patterns in specific cities
- Generating educational content about urban mobility
- Producing data-driven journalism pieces on transit
- Visualizing transit operator schedules for analysis
- Creating compelling map animations for presentations
Not Ideal For
- Projects requiring real-time transit tracking or live data updates
- Web developers needing embeddable, interactive map visualizations for online content
- Teams seeking a fully automated, cloud-based visualization pipeline without local software installation
- Users needing advanced data analysis features beyond basic frequency visualization
Pros & Cons
Pros
Directly downloads scheduled transit data from the Transitland API using simple command-line arguments, eliminating the need for manual data fetching and parsing.
Supports visualization by operator Onestop ID or geographic bounding box, with options like --clip_to_bbox and --exclude for tailored, focused animations.
Enables exporting animations as video files at different quality levels, including high-resolution outputs with 3,600 .tiff frames for presentations or publications.
Allows panning, zooming, and switching between multiple map providers (e.g., Stamen, Carto) via keyboard shortcuts in the Processing environment.
Cons
Requires manual installation of Processing 3, Unfolding Maps library, and Python dependencies, which involves multiple steps and can be error-prone for new users.
Relies solely on Transitland's scheduled data, excluding real-time updates or service changes, which reduces accuracy for current transit conditions and live monitoring.
Based on Processing, a desktop application, so animations cannot be easily embedded in web pages or shared online without exporting and converting videos first.
Uses Unfolding Maps version 0.9.9 for Processing 3, an older version that may not be actively maintained, leading to potential compatibility issues with newer systems.
