Placing sensors on dogs would allow people to gauge how busy parks are at a particular time, and help decide whether to make a trip or not. We could also tag children’s buggies and park benches so that we could map out particular types of usage.
Incentivising people to take and upload photos of how full their local recycling bins are would prevent top-floor tenement dwellers from making a wasted journey (and dumping their recycling into general waste). We could could do this by developing an app which would give micro-payments to responsible citizens and help to create value within a community.
Placing digital displays on the outside of buses that visualise how full they are and how many car journeys they are saving could help encourage more sustainable travel.
