1. Transit officials have identified a problem that they want to solve. Due to expansion, numerous bus routes have been recently added. Many of those routes stop at the same bus stop. Riders want to know what the next bus will arrive at each stop. They also want to know how much time they have to get to the bus stop. Before the new routes were added, riders could simply rush to the stop when they saw a bus coming—but that doesn't work anymore because it might not be the bus that they're expecting. The city has developed a way to know how far away each bus is from a stop, but they aren't sure how to share that information with riders.
