Conference Paper
Full-text available
Autonomous driving has started to receive attention not only by the research community but also by planning practitioners and policy makers concerned with urban development. There is great concern and perhaps even greater uncertainty about how autonomous vehicles in cities may possibly affect a core domain of city planning: the interaction of the t...

We provide an in-depth theoretical discussion about the differences between individual-specific latent constructs (representing attitudes, for example, but also other characteristics such as values or personality traits) and alternative-specific latent constructs (that may represent perceptions) affecting the choice-making process of individuals; w...
Article
When designing stated-choice experiments modellers may consider offering respondents an “indifference” alternative to avoid stochastic choices when utility differences between alternatives are perceived as too small. By doing this, the modeller avoids adding white noise to the data and may gain additional information. This paper proposes a framewor...
Article
The main objective of this paper is to compare the consequences of treating the attitudinal and perceptual indicators of hybrid discrete choice (HDC) models as continuous or ordinal outcomes. Based on tradition and computational reasons, such indicators are still predominantly treated as continuous outcomes in practice. This usually neglects their...

Article
Full-text available
It is well-known that not all the variables affecting decisions in a discrete choice situation are objective characteristics of the alternatives. Some of them are associated with difficult to measure attributes which may be represented as latent variables. Since this type of variables cannot be directly observed by the analyst, they must be estimat...
Conference Paper
Full-text available
It is fact that not all the objective characteristics of alternatives affect decisions directly in a choice model. Some of them affect individual decisions through changes in the valuation of immeasurable alternative attributes, which are usually represented as latent variables. Traditionally, these characteristics have not been taken into consider...

Abstract As bicycling as a mode of transport for everyday mobility gains increasing interest from both the public and from policy makers in Germany (Abt. 3 Verkehrsplanung, Referat für Stadt-planung und Bauordnung, Landeshauptstadt München, 2015) (Senatsverwaltung für Umwelt, Verkehr und Klimaschutz, n.d.) (Tomik, 2018), the need to include bicycling in the transport models that support policy evaluation procedures becomes pressing. This study used an online stated preference survey and discrete choice modelling to investigate the effects of street environment attributes on bicyclists’ route choice in Berlin, Germany. Included among the attributes were two urban design characteristics, complexity – expressed as a contrast between historical and post-war buildings in Berlin - and streetscape design. Both multinomial logit models with interaction parameters and mixed logit models with random coefficients were estimated. The results of these models show that both urban design characteristics have a significant effect on the route choice of bicyclists. The results also confirmed many hypotheses concerting the effects of street environment attributes, including several related to pavement types, motorized traffic volumes, and bicycle type used by the bicyclist. The results are also suitable to use as input for traffic modelling programs such as MATSim (Horni, Nagel, & Axhausen, 2016).
Project
The aim of the project is to analyze the full potential of autonomous and connected driving and to create a dialogue between the relevant stakeholders who play a crucial role in the implemen-tation of the technology in the traffic system in Germany. In-depth research analysis on the po-tential opportunities and risks from the implementation and use of vehicle automation will build the base for this dialogue. This work aims to ensure that automated and connected driving con-sider residents´ mobility needs, contribute to create a sustainable and more efficient traffic system, and support Germany as a market leader for this technology. Potential opportunities and risks of the implementation and use of automated and connected driving as well as users´ and stakeholders´ requirements for the technology will be addressed in a literature review, quantitative surveys, and interviews and workshops. An additional part of the project is to support knowledge and experience exchange between government funded research projects addressing automated and connected driving by organizing regular workshops and summarizing important achievements and results from these projects. Moreover, action fields for the implementation of the technology in the traffic system and a comprehensive concept for future dialogue between relevant stakeholders will be derived from the results of the project. An important starting point for the analysis within the project is the National Strategy for Automated and Connected Driving published by the German government. The project is funded by the Federal Ministry of Transport and Digital Infrastructure.
