Digital Matatus project makes the invisible visible

Most cities in the developing world rely on informal networks of minivans and buses to bring laborers to work and goods to market. Yet little information or data are available about these networks, where bus stops can change by the minute and fares can quadruple when it rains. In cities from Bogotá to Addis Ababa, commuters and suppliers can only find their way through word of mouth. And these informal but essential networks are almost invisible to planners who pilot urban expansion and development.
