“Everywhere I go, I see incredible examples of communities that have a vision for transportation and how it will impact the quality of life, mobility, economics and opportunity.” - Anthony Foxx

Mass public transportation is not only a sign of growth - it is also a key factor in the development of major cities around the United States. Public transportation moves people forward. Where are these connections happening? This data visualization project aims to explore the top 10 major mass public transit systems across the U.S. and compare them.

Visualizing Transportation

These are the top 10 major mass transit systems of cities across the United States. Seeing the map was extremely important because it acts as the skeleton of a city. Users can scrub along the timeline on the bottom to see when each system was opened to the public.

Double Info Panel-01

Compare Two Systems

Users can choose two transit systems to compare their statistics. This could be helpful for people moving or travelling to new cities so they can get a sense of other systems.

Learn more about a system

Users can also learn more about each individual system. The overview provides statistics about the system, as well as an image of the card and the fare. Each transit system is different from the other, and their cards are completely unique.

Explore the Transit Map

This is an expanded version of the maps that are shown in the bubbles of the main screen. They are the exact maps that would be found in the stations so they are unique to their system.


Seeing Congestion

One of the most important factors that can make a break the experience of a trip is how crowded it is. The Timeline feature allows users to have an overview of congestion throughout the day. The red areas on the timeline are the most crowded times of the day. This timeline also lets users know the operating hours of each system. The design of the train cart is modeled after the train carts of each system.


My initial focus was all on the maps. I wanted to create something where people could visualize all the little lines that kept people moving in each city. Then came the idea of comparisons and viewing statistics of each system because I wanted to provide valuable information beyond the visuals.


Transit Inspiration

I was extremely inspired by the simplicity of these maps. The forms and the colors of the lines are the focus and the background is almost undetectable. The lines are big, bold, and bright.

Maps can be extremely convoluted, so it was important to keep the other areas of the design as simple and as clean as possible.


As I was creating the wireframes, I had a lot of trouble displaying the transit maps on the U.S. map. I originally pictured the main screen as just the forms of the maps, however after realizing how tiny they are in actual scale, I decided to put the maps in magnifying bubbles.
