I remember when I was living on a University campus and had to try to decide each day whether I should wait for a shuttle bus or just walk. The problem was, of course, not knowing how long I would have to wait. Well, Ublip is helping Tufts University solve that problem. Soon students will be able to look at a monitor and see exactly how where the shuttles are as well as an estimated time of arrival. Shortly after that, they will be able to get this information using their cell phones.
