A study of daily time allocation to travel and out-of-home activity is conducted across eight European cities over three countries: France (Lyon, Grenoble, Strasbourg and Rennes), Switzerland (Geneva, Bern and Zurich) and Belgium (Brussels), based on individual travel survey data collected...

This paper suggests understanding better the debate between reputation and celebrity, by analyzing how various types of reputations can combine (or not) to achieve celebrity. Based on a quantitative analysis of the most reputed French architects, we contribute to the reputation and celebrity...

The paper concerns the travel activities and more specifically the urban travel time during a day. The daily TTB has been hypothesized by Zahavi (1980) as constant amount of time. First, the cities sprawl can easily be interpreted as a consequence of the increase in available speeds. And...

Understanding travelers' daily travel-activity pattern formation is an important issue for activity-based travel demand analysis. The activity pattern formation concerns not only complex interrelations between household members and individual's socio-demographic characteristics but also urban...

Escaping unidimensional analysis limits and linear regression irrelevancy, the duration model incorporates impacts of covariates on the duration variable and permits to test the dependence of daily travel times on elapsed time. In the perspective of a discussion of Zahavi's hypothesis, the...

The paper is concerned with the travel activity and more specifically the urban travel time during a day. This individual mean travel time budget (TTB) has been hypothesised by Zahavi (1980) to be a constant amount of time close to 1 hour per day. This TTB seems to be stable between different...

The analysis presented in this paper is based on the database created by the UITP (International Association of Public Transport), "The Millennium Cities Database", which covers the public transport systems in 100 of the world's cities. It contains data on demography, urban structure, transport...

The paper exams the relationships between travel and activity times, in 7 travel surveys from 4 French and 3 Swiss cities, observed at two different periods. First, we test proportional assignment of total daily available time to activities (including transport). Second, proportionality is...

The relationship between travel time budget (TTB) and speed is central to transport economics and allows us to analyze travel behaviour, urban structure and the transport system. Together, this relationship and Zahavi's hypothesis provide a straightforward mechanism that explains the increase in...

This study investigates the influence of observed explanatory factors and unobserved random effect (heterogeneity) on episode durations of travel-activity chain. A shared frailty semiparametric proportional hazard model is proposed to estimate the transition hazard of travel/activity states. The...
