The brief was to change the behaviours of London and its people to have a positive impact on its transport system. After some extensive research we found out the truth about London's pollution problems (London's pollution contributes to 50,000 deaths a year, and wont be a legal level until at least 2025). We knew we had to warn and help the people it affected. Therefore we chose to target people who commute round London by walking or cycling as we knew they were actually getting affected by this problem the most. In turn we created an integrated plugin app for Citymapper, Nike+, Fitbit etc that would reroute their journeys to a lesser polluted route. If a health benefit wasn't enough to persuade them to take these fresher routes, they can also work towards tailored rewards by taking the greener journey.
