Two studies are reported examining the adaptations people make in order to achieve car-use reduction goals set in response to travel demand management (TDM) measures. Study 1 examined retrospective reports of actual behavioural adaptations made in response to the introduction of the Trondheim toll ring. Building upon the first study, Study 2 was an internet survey requiring respondents to state the frequency with which they would adopt various adaptation alternatives were they required to adapt to a small, medium, or large car-use reduction goal. The frequency with which a particular adaptation is implemented was found to vary with trip purpose and with size of reduction goal. The results were interpreted in the light of a modified cost-minimisation principle of adaptation.
