Conserved quantities in human mobility
(2022)Arbeitsberichte Verkehrs- und RaumplanungQuantifying intra-person variability in travel choices is essential for the comprehension of activity-travel behaviour. Due to a lack of appropriate datasets and methods, there is limited understanding of how an individual’s travel pattern evolves over months and years. We use two high-resolution user-labelled datasets consisting of billions of GPS track points from ∼ 3800 individuals to analyze individuals’ activity-travel behaviour over ...Working Paper -
Towards comparability in residential location choice modeling
(2013)Arbeitsberichte Verkehrs- und RaumplanungWith the availability of disaggregated spatial data, residential location choice models have become more and more diverse in the hypothesis tested. This reduces the comparability of the main findings in different studies, although one might expect a comparable human behavior for comparable study areas. In the paper we review recent literature of the residential location choice models on a disaggregated level, in order to conclude in a set ...Working Paper -
Inertia effects of past behavior in modal shift behavior
(2020)Arbeitsberichte Verkehrs- und RaumplanungThis paper focuses on empirically investigating the inertia effects of past behavior in modal shift behavior and contributes to the current state of the art by three aspects. Firstly, this study introduces and tests the potential influences of the inertia effect of past behavior on the traveler’s preferences regarding level-of-service (LOS) variables, besides the impacts of inertia effect on the preference for the frequently used transport ...Working Paper -
Commuting distance and individual accessibility
(2018)Arbeitsberichte Verkehrs- und RaumplanungIn the present study a methodology to construct individual-based accessibility measures is introduced. Building on the concept of specifying the distance decay function as a survival function, the transition from a data-driven approach for aggregate distance decay functions, to a model- based approach for individual-based ones is presented. Based on this, the construction of location- and person-specific accessibility measures is facilitated, ...Working Paper -
Within-day replanning of exceptional events
(2011)Arbeitsberichte Verkehrs- und RaumplanungTypical software that is used for the simulation of traffic behavior focuses on scenarios that describe common situations like an ordinary working day without remarkable incidents. To simulate such scenarios, iterative approaches are used. They assume that the simulated people adapt to the results of the previous iterations. Such iterative approaches produce meaningful results for various scenarios as long as only typical, repetitive ...Working Paper -
Modeling household fleet choice as a function of fuel price using a multiple discrete-continuous choice model
(2011)Arbeitsberichte Verkehrs- und RaumplanungIn this Paper, a new model of fleet choice for households is presented that uses the multiple discrete-continuous extreme value (MDCEV) model as a framework. The aim of the model is to establish a model to allocate car types to activity based microscopic agent based transport simulations. What is new in the presented model, is that in addition to socioeconomic attributes of households, the choice is also influenced by fuel price. To model ...Working Paper -
Modelling urban mode choice behavior during the COVID-19 pandemic in Switzerland using MDCEV models
(2021)Arbeitsberichte Verkehrs- und RaumplanungIn this paper we describe and model the behavioral response of the COVID-19 pandemic in Switzerland. We use the MOBIS-COVID GPS-tracking dataset which includes a pre-pandemic reference base. We transform the trip-level data in weekly distance proportions per mode per week, and model the data using a multiple discrete-continuous extreme value (MDCEV) model. We derive four distinct segments from September 2019 until the end of 2020 and use ...Working Paper -

EpiSim Switzerland scenario
(2021)Arbeitsberichte Verkehrs- und RaumplanungIn Switzerland, 702000 people tested positive for the SARS-CoV-2 to date (June 20th, 2021) and 10875 died. Population-wide strategies including testing, tracking, tracing, social distancing, and the use of personal protective equipment are implemented all around the world to mitigate the impacts of the pandemic. Society, economy, and the most vulnerable groups of the population become central when designing the strategies to limit the ...Working Paper -
Impact of bicycle traffic on the macroscopic fundamental diagram
(2019)Arbeitsberichte Verkehrs- und RaumplanungInteractions between bicycles and cars have begun to attract increasing attention. This paper aims to investigate network-level car-bicycle interactions by quantifying the impact of bicycle traffic on empirical macroscopic fundamental diagrams (MFDs). First, the stratified re-sampling method is used to analyze the impact of bicycle-related facilities on network capacity and critical density. Then, the trapezoidal MFD function is applied ...Working Paper
