Distributed Knowledge
Transit riders in Pittsburgh will soon be able to get the answer for the most common question for who waits at a bus stop: Where's the bus? Thanks to Tiramisu, a new pretty straightforward iPhone application developed at Carnegie Mellon University, riders will be able to share arrival times with each other.
By using crowdsourcing to share information, anyone waiting at a bus or T stop with an iPhone can see which buses or light rail vehicles are due to arrive next and, thanks to the signals from riders already aboard, get an idea of how long they have to wait.
Tiramisu — "pick me up" in Italian — makes it easy for riders to use their iPhones to signal the location and occupancy level of the Port Authority of Allegheny County bus they are riding, in real-time.
