The purpose of this paper is to analyze the relationships between work and weekdays travel behavior of workers over the last 20 years. Two main directions are explored. We first investigate the nature and influence of work trips on travel behavior during working days. To this end not only commuting trips are taken into account but also business trips, defined as work-related travels to non regular workplace. Second we compare travel behavior and especially the characteristics of non-work trips of workers betweenworking and non-working days. The aim is to evaluate how work patterns and in particular work trips affect non-work trips. Data come from the 1983 and 2001 Travel Survey of the Paris Region. Only intra-regional travel aretaken into account. Results show firstly significant differences between working days, during which work trips dominate, and non-working days during which non-work trips are by far more numerous and also more diversified.Secondly three categories of workers are highlighted according to the nature of work trips which also have influence on non-work trips. By taking into account the nature of work trips and the distinction between between working and non-working days we thirdly propose another look at travel differences by gender and by professional status. Fourthly we highlight three main changes over the last twenty years: an intensification of differencesworking and non-working days, a diminishing of work trips and an affirmation of gender differences.
