  • Location relativity in space and time
    Item type: Report
    Portnov, Boris A.; Axhausen, Kay W.; Tschopp, Martin; et al. (2008)
    Arbeitsberichte Verkehrs- und Raumplanung
    The present paper looks into the context and time dependence of location effects, illustrating how it affects the long-term population growth of 2889 individual municipalities located in 26 cantons of Switzerland. The analysis demonstrates the cross-sectional and temporal relativity of location attributes, which appears to emerge clearly even for relatively small regional divisions, such as cantons. However, the difference between absolute and relative location attributes appears to diminish between 1950 and 2000. Another interesting finding of this study is that the statistical significance of most location attributes covered by the analysis appears to weaken over time, apparently due to improved road and rail infrastructures and increased motorization levels.
  • Stated response and multiple discrete-continuous choice models
    Item type: Working Paper
    Jäggi, Boris; Axhausen, Kay W.; Weis, Claude (2011)
    Arbeitsberichte Verkehrs- und Raumplanung
    In sophisticated transport models choice modeling is used to capture a wide range of behaviors, such as mode choice, fleet choice or route choice. A newly developed approach to improve realism is the multiple discrete-continuous extreme value (MDCEV) model, which allows to model the allocation of continuous amounts of a consumption good. Before using this models in overall frameworks, knowledge about the accuracy of the forecasting procedure is important. In this paper a MDCEV model of fleet choice based on data collected in a Stated Adaptation survey is presented. A forecast of the model predicting annual mileage of households to 17 different car types was made and the results were compared to the actual data calculating the residuals. The residual analysis shows that the model performs significantly better than a totally random model, but the share of wrongly allocated mileage, 70% of total, remains high. However an assessment of the result is difficult with only one model. The differences between two sub-models, one without public transport, another including it, regarding the distribution of the residuals indicate that the model specification has a big influence on its performance. Therefore, following work forecasting additional MDCEV models will be necessary to have a base for comparison. We compare two further MDCEV models to obtain a fuller understanding of their performance.
  • Investigating commute mode and route choice variabilities in Jakarta using multi-day GPS Data
    Item type: Working Paper
    Arifin, Zainal N.; Axhausen, Kay W. (2012)
    Arbeitsberichte Verkehrs- und Raumplanung
    This paper reports on findings regarding the day-to-day dynamic behavior of commuters’ mode and route choices in Jakarta. Ninety-three commuters using Global Positioning System (GPS) devices during a one-week period were observed. The observation proves the presence of dynamic behavior in choosing both modes and routes for commuting in Jakarta. Car drivers and motorcyclists frequently change their routes, especially during work-to-home trips. Motorcyclists were more dynamic in choosing their routes than were car drivers. This case study revealed a unique pattern of mode and route choice behavior, which can be used for developing a mode and route choice model for Jakarta.

  • Modeling location decisions of retailers with an agent-based approach
    Item type: Working Paper
    Ciari, Francesco; Axhausen, Kay W. (2012)
    Arbeitsberichte Verkehrs- und Raumplanung
    The paper reports about a project, where an agent-based module of location decisions of retailers has been implemented into the agent-based traffic simulator MATSim-T. The retailer module focuses on the retailers’ location choice. Retailers are modeled as agents in the simulation and are allowed to relocate their stores, according to a given strategy, in order to maximize the number of their customers. The paper discusses first the conceptual background of the model and then the actual implementation. A test case, a large scale scenario representing the urban agglomeration of Zurich, Switzerland, is presented. The discussion of the results focuses on possible practical applications of the tool and on further developments.
  • Interdependencies between turning points in life and long-term mobility decisions
    Item type: Working Paper
    Beige, Sigrun; Axhausen, Kay W. (2011)
    Arbeitsberichte Verkehrs- und Raumplanung
    Turning points in life include important personal and familial events as well as changes in the places of residence, education and employment. The latter usually involve alterations in the spatial distribution of activities and, hence, in the activity space, thereby also influencing the daily travel behavior. In this context, the ownership of mobility tools, such as cars and different public transport season tickets, also plays an important role, since people commit themselves to particular travel behaviors as they trade large one-time costs for a low marginal cost at the time of usage. At the same time, decisions concerning mobility tool ownership have lasting effects, as have the decisions concerning location choices. A longitudinal perspective on the dynamics of these long-term mobility decisions is available from people’s life courses, which link different dimensions of life together. In order to study these dynamics and the influence of turning points in life, a longitudinal survey covering the 20 year period from 1985 to 2004 was carried out at the beginning of 2005 in a stratified sample of municipalities in the Zurich region, Switzerland. The paper describes the data collection and then presents results which show that there exist strong interdependencies between the various turning points and long-term mobility decisions during the life course, as events occur to a great extent simultaneously. Persons tend to aim for compensation between the different dimensions of life.
