Invisible information: 1. How many pedestrians are waiting for a bus, and which bus 2. How much garbage is contained in the waste receptacle, and when it may require emptying. If public transportation users used an app that identified which bus they were waiting for, or if a node at the bus stop could measure how many are waiting for each bus, it could not only contribute to data to be used for bus planning, but could also make on-demand public transportation possible, whereby only as many vehicles are deployed as required at any given moment.
