Sustainable mobility • We aim for reduced congestion, reduced air pollution or improved safety by stimulating people to change their travelling behaviour. • We investigate how positive incentives can stimulate smart and sustainable traveling in urban regions. • 1. Smart phone application senses behavior • 2. System issues incentives , e.g. travel by bicycle and get a free coffee • 3. Smart phone application monitors impact of incentives. • 3 Living labs Enschede, Gotenborg and Leeds SUNSET EU review, Brussels, March 27, 2012Info.nl big data 9-8-2012 19 19
