Samenvatting
The effects of different public information messages on the speed choice, in particular on blind curves, on roads with an 80 km/h limit were investigated using behaviour versus attitude-oriented information messages on roadside posters or leaflets distributed amongst households. At five locations driving speeds were registered before, during and after the campaign. In addition, a postal survey was carried out before and after the campaign. The highest speed reductions were achieved with behaviour oriented messages on roadside posters. Relevant changes in opinions and attitudes were not found in any of the conditions. For the second and third experiment see IRRD 818173 and 818177.
