In 2012, the company Transit Screen launched a new service that makes choosing a method of public transportation much easier. The company’s digital signage aggregates real-time information for any mode of public transit in a city—subways, commuter trains, buses, bike share, ride shares—and displays this info in university buildings, the lobbies of dwelling buildings and offices, and more.

Transit Screen debuted as part of a government pilot program in Arlington, Virginia, and today they are up and running in seven cities. Now, the company has announced that it is outside of private lobbies and onto the city street.

Transit Screen’s latest attempt, Smart Walk, involves bringing the same real-time dashboard of information into the physical world by projecting the information onto public spaces. In addition to the real-time transit data provided by the screens, the projections would also insert way-finding information for transit options on sidewalks, walls, plazas, or even billboards: think arrows pointing you in the direction of the bus, subway, or bike share.

Interested in the new ways Smart Walk can activate the public space. "It’s a dynamic use of real-time information that cities haven’t seen before," Croft tells Co.Design. "They really like it because it’s something that has such broad reach." The company is currently in talks to install a nightly projection at Great Wall of Oakland.

Though some transit apps, like Ride Scout, provide similar data on the fly, their reach is limited to those who have a smart phone, and who know to download the app. With both the original Transit Screen displays and Smart Walk, the information is displayed for anyone who walks by.
