Sustainable social networking services for transport.


We investigate how positive incentives can stimulate smart and sustainable traveling in urban regions.

In the transportation research field, incentives may take various forms, ranging from positive to negative incentives. ‘Positive incentives’ aim to reducing car use by improving travel choices and offering rewards. This way, car drivers who reduce their driving are benefited but those who do not are not negatively affected. Examples of such incentives are park and ride, teleworking or transit improvement. Vice versa, ‘negative incentives’ focus on mechanisms that make car drivers be at disadvantage if they do not reduce their car use. Therefore, most (if not all) pricing policies fall into this category, such as fuel tax, parking fees, and congestion charges.

In the SUNSET project we investigate

  • those incentives that have most potential to change travel behaviour;
  • design features of incentives to increase feasibility and efficacy in changing travel behaviour;
  • influence of city contexts (the different living labs) and social categories and incentive types.

Specifically, we focus on four types of incentives:

  • Real-time travel information (i.e. system provision and peer-to peer exchange);
  • Feedback and self-monitoring;
  • Rewards and points;
  • Social networks.
