[pop-up] urbain on 27 Oct 16"exico City has over 1,500 ya-kinda-just-gotta-know-about-them bus routes making up one of the largest bus systems in the world. The buses, or "peseros," are the primary mode of public transit in the city, accounting for 60 percent of Mexico City's commutes. That's 14 million rides a day. But nobody knows exactly where all of the buses go. There is no official route map. Pinning down the system and all its routes presents a daunting task, but this month, a group of collaborators achieved it by creating a citywide participatory mobile app game. They relied on crowdsourcing, cell phones and algorithms to make it happen."
