Understanding individual travel decisions: results from a commuters surveyin Geneva

In this paper, we present the results of an extended traveler behavior surv ey conducted in Geneva (Switzerland) in March 1994. In this survey, commute rs were asked about the impact of various factors, related to individual or household characteristics and situational, contextual and environmental co nstraints on their basic travel decisions. In particular, the issues of mod e, route and departure time choice were investigated, together with the div ersion from normal patterns in response to adverse weather conditions. Some cross cultural comparisons are discussed with respect to the results of a similar survey conducted in Brussels (Belgium) in 1992 (Khattak & de Palma 1995, 1997).
