Explaining differences in acceptability before and acceptance after the implementation of a congestion charge in Stockholm

A field experiment was conducted in Stockholm where a congestion charge trial was introduced in 2006. Respondents completed a questionnaire before and after the trial. Acceptance of the congestion charge was higher after the trial as opposed to its acceptability judgments before the trial. Respondents believed the charge had more positive consequences (viz., decreasing parking problems, congestion, and pollution) and fewer negative consequences (viz., financial cost increases) after the trial than they had expected beforehand. Furthermore, the study examined the relative importance of various beliefs for the acceptability of the congestion charge before and after it was implemented. Results are that before the implementation of the charge acceptability was significantly related to beliefs about the expected consequences for one's own car use and financial costs, whereas acceptance after the trial was related to beliefs about the perceived consequences for one's own car use and parking problems. These results indicate that acceptance of the congestion charge had increased because people experienced positive consequences of the charge. This conclusion is discussed in the broader context in which the Stockholm trial took place.
