25 Great Ways Colleges Are Using Crowdsourcing

Carnegie Mellon University has created an iPhone application that solves this problem, telling transit riders where their bus is, as well as how full it is. Where does the information come from? The people on that very bus. And the great part is that the existing riders don’t have to do anything at all — their signals from the app will indicate location, and the number of signals indicates fullness. This project is a great feat of hands-off crowdsourcing for the common good.
