Recent research in the field of mode choice has revealed a lack of knowledge concerning the decision making process and certain elements of this process in particular. In accordance with this conclusion the Traffic Safety Research centre of the University of Groningen has carried out an experiment which deals exclusively with the decision making process in mode choice. Considering that mode choice is determined by a large number of factors, this first experiment had a limited design. Attention was focussed on two elements of the decision making process, namely the decision rules people use in choosing their travel mode, and the process of information gathering for this choice. In the experiment 60 people were confronted with four trips. The trips consisted of two home to work trips, about 7 and 20 kilometers respectively, a shopping trip, and a recreational trip. The journey took place in unfamiliar surroundings in order to eliminate the effects of habit. Therefore people were forced in a "reconsideration phase" with regard to their mode choice. For each of the four trips four alternative modes of transport were available. The attitudes towards the actually used travel modes in the experiment show that for shorter distances there is a positive attitude towards the bicycle, and a negative attitude towards the use of public transport. For longer distances there are positive attitudes towards the use of train and car, and a negative attitude towards the bus. Young people show a significantly more positive attitude towards the use of the car than other age groups. This point might produce difficulties when limitations on car use are introduced. The actual mode choice subjects finally made is further analysed. In a "reconsideration phase", such as was constructed in the experiment, people are inclined to compare alternatives. By presenting information to the decision maker the use of certain travel modes can be encouraged. Presenting this information itemwise, and therefore for multiple travel modes at the same time, could stimulate a decision maker into making a comparison between travel modes. (TRRL)
