This paper discusses the latest microcensus on travel behavior in Switzerland, held in 1994. The growing variety of users interested in this piece of information, such as planning authorities, marketing departments of public transport companies, insurance companies and many others, requires a permanent growth of the surveys' topics. Compared with former surveys on travel behavior, the 1994 study design underwent a number of substantial innovations, thus better covering and informing on the daily travel patterns in Switzerland. The main changes consist of a switch from a written survey form to computer-assisted telephone interviewing. The careful and extensive procedures of contacting the persons selected for the interview, the numerous possibilities of on-line plausibility checks and the explanatory support in direct dialogue lead to a substantial decrease of overall and of item nonresponse. In addition, the computer-assisted telephone interview is able to cope with a degree of complexity, which is necessary for the recording of every single stage of all daily trips recorded for one day. Thus, it has been possible to record, for the first time on a national level, the manifold combinations of different public and private, motorized and non-motorized transport modes chosen for each single trip. |
