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 -

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 -
Understanding Travel and Mode Choice with Emerging Modes
(2019)Arbeitsberichte Verkehrs- und RaumplanungResearch presented in this paper analyzed two data sets from Revealed Preference (RP) and Stated Preference (SP), obtained with a new travel diary and mode choice survey. This survey, called Mobility Jakarta, combines both revealed and stated preference parts and was conducted in the Greater Jakarta region. This is the first survey that collected responses from a substantial sample of the population across the whole metropolitan area. We ...Working Paper -
Impact of major road supply on individual travel time expenditure
(2017)Arbeitsberichte Verkehrs- und RaumplanungThis study estimates the impact of major road supply on individual travel time expenditure (TTE) using data on 30-year changes in transportation infrastructure and travel behavior. The impact observed shortly after the improvement to the road infrastructure is estimated from a data set that combines records on large-scale household travel surveys in the Tokyo metropolitan area conducted in 1978, 1988, 1998, and 2008. Linear and Tobit ...Working Paper -
Expanding a (electric) bicycle-sharing system to a new city: Prediction of demand with spatial regression and random forests
(2019)Arbeitsberichte Verkehrs- und RaumplanungThe number of bicycle-sharing systems has undergone strong growth in the last two decades. This growth is part of a worldwide trend that has began in the 1990s and has strongly accelerated after 2005. Early bicycle-sharing systems have mainly been provided as a public service by cities, but meanwhile major international bicycle-sharing companies have emerged that seek to expand their operations to new cities. Two major strategic questions ...Working Paper -
High-resolution destination choice in agent-based demand models
(2011)Arbeitsberichte Verkehrs- und RaumplanungThis paper describes the modeling of destination choices for discretionary activities in a multiagent transport simulation, using MATSim as an example. MATSim is based on utility maximization and its utility function has always been deterministic. Unobserved heterogeneity is now added to the utility function through a random error term, meaning that MATSim is now fully compatible with discrete choice theory. Real-world simulation results ...Working Paper
