The paper deals with empirical data to learn about the use and compliance of Traveler Information Systems for leisure trips in winter tourism. Within the vicinity of skiing resorts in the Alps traffic problems arise because of very high seasonal peaks on low road capacity. Since extending road capacity is not a feasible option, a research project is undergoing to improve the usage of the given transport infrastructure by means of traveler information. In order to quantify the potential and provide data for a most effective Traveler Information System a computer aided personal interview (CAPI) with 1188 valid interviews and a computer aided self interview (CASI) has been conducted within the skiing resorts of the Saalachtal (Austria). The surveys indicate a high open-mindedness of skiing tourists towards new Traveler Information Systems. The internet is widely being used for pre-trip information while onboard devices (e.g. Personal Navigation Devices (PND)) dominate on-trip information. Routine behavior is the most important item for not making use of such travel information. A CHAID-analysis has been applied to identify key factors influencing the use of such devices. The use of pre-trip information depends on trip purpose and the mental map while on-trip information relates also to personal characteristics like age and employment. Routing information combined with data on snow conditions are most important for all respondents. 30% of all PND-users actually strictly follow the navigation advice, which is quite relevant for the anticipated traffic control strategies.
