[en] An important policy instrument for governments to modify travel behavior and manage the increasing
travel demand is the introduction of a congestion pricing system. In this study, the influence of a detailed
classification of activities is examined to assess likely traveler response to congestion pricing scenarios.
Despite the fact that most studies do not differentiate between activity categories, the value of time and in
general the space-time properties and constraints of different types of activities vary widely. For this
reason, it is of importance to provide sufficient detail and sensitivity in assessing the impact of congestion
pricing scenarios. In addition, a first assessment of possible multi-faceted adaptation patterns of travelers
is presented. For these purposes, a stated adaptation study was conducted in Flanders (Dutch speaking
region of Belgium). The experiment was conducted through an interactive stated adaptation survey. In the
stated adaptation experiment respondents could indicate their stated responses to the congestion pricing
scenario. The most prevalent conclusion is that the activity type significantly predetermines the
willingness to express a more environmental-friendly behavior (i.e. reducing the number of trips,
reducing the total distance traveled, switching to more environmental-friendly modes). Also, the
willingness to show ecological activity-travel behavior (e.g. carpooling and using public transport) in a
non-pricing situation is a major differentiator of future behavior in a congestion pricing scenario.
