Dude, where’s my bus: CMU-developed transit app will help riders find a ride and a seat

With so many questions swirling around, riders now can at least get answers to two of them — “Where’s my bus?” and “Can I get on it?” — courtesy of a new smart-phone application from Carnegie Mellon University. The free app, called Tiramisu (Italian for “pick me up”), uses crowdsourcing — a method by which information is gathered from users, rather than stemming from a central source — to report the real-time location, estimated arrival time and capacity of oncoming Port Authority buses and light-rail vehicles.
