Randomized Controlled Trial
Persuading drivers to refrain from speeding: Effects of message sidedness and regulatory fit.
Building on regulatory fit theory (Higgins, 2000, 2005), we tested whether two-sided ads were more effective than one-sided ads in changing intentions toward driving behavior when message recipients were high in assessment orientation rather than locomotion orientation. In one study either a locomotion or an assessment orientation were situationally induced (Study 1) and in another study these different orientations were chronic predispositions (Study 2). ⋯ There was also evidence that the fit effect on intentions to comply was mediated by strength of engagement with the message. Implications for persuasion concerning driving behaviors are discussed.

Randomized Controlled Trial
Safety effects of permanent running lights for bicycles: A controlled experiment.
Making the use of daytime running lights mandatory for motor vehicles is generally documented to have had a positive impact upon traffic safety. Improving traffic safety for bicyclists is a focal point in the road traffic safety work in Denmark. In 2004 and 2005 a controlled experiment including 3845 cyclists was carried out in Odense, Denmark in order to examine, if permanent running lights mounted to bicycles would improve traffic safety for cyclists. ⋯ The study shows that use of permanent bicycle running lights reduces the occurrence of multiparty accidents involving cyclists significantly. In the study the bicycle accidents were recorded trough self-reporting on the Internet. Possible shortcomings and problems related to this accident recording are discussed and analysed.
