ElectriCity Innovation Challenge 2015 was an open innovation contest in Gothenburg, Sweden. The main purpose was to surge public interest and involvement in ElectriCity, a demonstration arena for next-generation's electrified bus systems. The contest furthermore aimed to catalyse innovation that can contribute to making public transport more attractive, and to test a novel innovation platform that assembles data from buses and bus stops. The outcome was six events with a total of more than 800 attendants, 48 viable prototypes with potential to increase the modal share of electrified public transport and feedback on the innovation platform's potential for development.
