    How Data Visualizations Are Making Public Transportation Beautiful

    Bruno Imbrizi's "experiment 7."

    Whether public transportation is the bane of your existence, a necessary evil, or your favorite part of modern infrastructure, we all can agree that, at the very least, subway cars and buses make some pretty damn great data visualizations.

    Bruno Imbrizi is the latest developer to add to the already sizeable catalogue of transport visualizations. His project, announced on Tuesday and only known as “experiment 7,” uses data acquired from the London Underground to generate a three-dimensional tube map that is equal parts elegant and disorienting.

    Imbrizi’s visualization is fully interactive. Visitors can choose which lines to watch, the speed of the visuals themselves, and the angle from which to view the whole system. For whatever reason, neither the Circle nor the Waterloo and City Lines are available, but it otherwise displays the entire underground based on prediction summaries acquired from Transport for London.

    Of his design, Imbrizi wrote on his blog that, “I wanted more of a cool visualization based on the tube data, rather than an informative/useful map.” His goal was to do something new. Originally, his plans included creating an auditory component to his visualization. “I could assign a different note for each line and the live feed would create random music all day long,” he wrote. Unfortunately, he quickly realized this wasn’t possible and changed course.

    However, Imbrizi’s sonification idea has been touched upon before for other cities. A two-year old visualization created by Alexander Chen, Creative Director for Google New York's Creative Lab, uses a similar idea to turn the New York subway system into a virtual stringed instrument, even mimicking the vibration of strings as lines traverse one another.

    Chen’s visualization, called Conductor, begins with real-time data. At whatever time the page is opened, the viewer will see trains operating as they are at that very moment. Conductor then speeds up to cover the twenty-four hour loop of subway cars as they move on their pre-determined paths. It looks like a more vivacious version of Snake.

    Another visualization worth noting is Dots on the Bus, winner of the 2013 Urban Data Challenge by Urban Prototyping. The aim of the project is to make riding the bus less intimidating by displaying the daily life of the municipal bus systems of three separate cities: San Francisco, Geneva, and Zurich.

    The data is not real-time, but rather based on information provided for a particular week in October of last year, and the visualization itself is a little messier than the minimalist offerings of Imbrizi and Chen. But that’s not too big of a deal—it is still fascinating to watch the dots that represent travelers board and leave buses as the day progresses.

    There are plenty of apps that will tell you when the next bus or train is arriving. That is not the purpose of these projects. Instead, these visualizations were created so that we could bask in collective wonderment at the beauty of public transport from afar, without having to worry about how late, how smelly, or how loud the next train car will be.
