Predictions of Route Choice and the Effect of Choice on Judgements of Mean Speed: Differentiation and Consolidation

Traffic research strives to predict drivers’ route choice in order to adapt roads and speed limits in an economically and environmentally optimal way. The present study aims to predict route choice from subjective judgements of mean speed over a given driving distance. Participants were asked to choose the fastest route out of two. Predictions were based on a previous study by Svenson and Salo (2009) where mean speeds of the same routes were evaluated. Previous judgements of mean speed were a significant predictor of route choice whereas objectively optimal choices were not. Differentiation and Consolidation theory predicts that choice changes judgements of alternatives so that they support the chosen alternative. The results show that the mean speed of a chosen alternative was judged as faster after compared to before choice. There was also a significant positive association between self-reported judgement skill and an equivalent objective measure.
