Accessibility
(2008)Arbeitsberichte Verkehrs- und RaumplanungImproved accessibility and its correlate lower generalized cost of contact, travel andtransport have been sought by dynamic human societies for their economic and social benefits throughout recorded history. The paper will reflect about this process at a number of different spatial and temporal scales based on a conceptual model. Looking back at European history, it will trace the interaction between Christaller’s logic of local market ...Report -
Stability in individual daily activity-travel-location patterns
(2007)Arbeitsberichte Verkehrs- und Raumplanung--> Using Herfindahl-Hirschman Index and the Mobidrive and Thurgau six-week travel diary datasets this paper examines the stability of individuals’ choices of their daily activity-travel-location combinations within multi-day period. The results show that the stability of individual activity-travel-mode-location combinations is highly influenced by the individuals’ out-of-home commitments, the intra-household conditions and the availability ...Report -
Activity spaces, biographies, social networks and their welfare gains and externalities
(2005)Arbeitsberichte Verkehrs- und RaumplanungThe repeated interactions and exchanges in formal and informal networks, e.g. family, firms, associations, friendship circles, regulars of a bar, are central to our daily life. There is no reason to assume, that the geography of the members of the networks, to which one belongs, has not been affected by the seminal drop in transport and telecommunication costs since 1950. The paper will develop a conceptualisation of the dynamics of the ...Working Paper -

Verkehrsinfrastruktur und räumliche Entwicklung
(2006)Arbeitsberichte Verkehrs- und RaumplanungDas Projekt Räumliche Erreichbarkeiten und regionale Disparitäten hat zum Ziel, im Rahmen einer quantitativen ex-post Analyse die Veränderungen der Raumstruktur einerseits und die Ent- wicklung der Verkehrsinfrastruktur und Transportdienstleistungen im Zeitraum zwischen 1950 und 2000 nachzuzeichnen. Methodisch stützen sich die Arbeiten sowohl auf herkömmliche Multiple (OLS), wie auch auf hierarchische Regressionsmodelle ab. Dieser Bericht ...Working Paper -
Calibration of a joint time assignment and mode choice model system
(2005)Arbeitsberichte Verkehrs- und RaumplanungIn this paper we report the results of applying a new microeconomic framework to model time assignment to activities, goods consumption and mode choice jointly (Jara-Díaz and Guevara, 2003; Jara-Díaz and Guerra, 2003) that identifies the links between these decisions and permits the calculation of all the components of the subjective value of time defined in the literature: the value of time as a resource, value of assigning time to a ...Working Paper -
Pre-commitment and usage
(2000)Arbeitsberichte Verkehrs- und RaumplanungTravellers commit themselves to particular behaviours through the ownership of cars and season tick- ets. They trade a large one-off payment for low or zero marginal cost at the point of use. To the knowledge of the authors there is no literature which addresses this joint decision. The paper presents an initial model based on a small Swiss 1999 representative sample survey. Using a structural equation model to test a-priori hypotheses ...Report -
