The Swiss Constitution prohibits road user charging. A possible introduction of new forms of pricing for the use of transport infrastructure needs in the first place the acceptance of the Swiss population. The research project "Acceptability of Mobility Pricing" (part of the research package 'Mobility Pricing' of the Federal Roads Office (FEDRO) investigates individual and political acceptance and builds up on existing analyses.

At the centre are the following questions:

• Which general conditions will cause Mobility Pricing to be accepted?
• Which configurations (models) of Mobility Pricing will be accepted and how well?
• Which factors are critical regarding acceptance, which factors are less relevant?
