Data-Enhanced Design: Engaging Designers in Exploratory Sensemaking with Multimodal Data

Research in the wild can reveal human behaviors, contexts, and needs around products that are difficult to observe in the lab. Telemetry data from the use of physical products can help facilitate in the wild research, in particular by suggesting hypotheses that can be explored through machine learning models. This paper explores ways for...

The relationship between cycle track width and the lateral position of cyclists, and implications for the required cycle track width

Sufficient cycle track width is important to prevent single-bicycle crashes and collisions between cyclists. The assumptions on which the minimum width is based in guidelines is founded on only a few studies. The aim of the present study is to investigate the relationship between cycle track width and lateral position of cyclists. Method: We...

Do cyclists need HMIs in future automated traffic?: An interview study

Cyclists are expected to interact with automated vehicles (AVs) in future traffic, yet we know little about the nature of this interaction and the safety implications of AVs on cyclists. On-bike human–machine interfaces (HMIs) and connecting cyclists to AVs and the road infrastructure may have the potential to enhance the safety of cyclists....

Spatial Activity-Travel Patterns of Cyclists

Knowledge about the way how the bicycle is used for activity participation is still scarce. This thesis provides empirical insights into typical activity-travel behaviour of cyclists. A special focus is put on the spatial dimension of activity-travelling by bicycle and its determinants. The findings can be used to design more bicycle-friendly...

Cycling Economics

Cycling is increasingly receiving attention in research and policy and practice, in many cities and regions in the world. The focus is mainly on cycling infrastructure and effects on travel behavior and health. The economics of cycling have not received a lot of attention yet. This chapter gives an overview of the current state of knowledge...

Estimating cycling aerodynamic performance using anthropometric measures

Aerodynamic drag force and projected frontal area (A) are commonly used indicators of aerodynamic cycling efficiency. This study investigated the accuracy of estimating these quantities using easy-to-acquire anthropometric and pose measures. In the first part, computational fluid dynamics (CFD) drag force calculations and A (m²)...

Insights into factors affecting the combined bicycle-transit mode

This paper considers an increasingly popular, sustainable multimodality: the combination of bicycle and transit. The flexibility of the bicycle combined with the speed and comfort of good transit can be a highly competitive alternative to the car. This study shows that many factors influence the uptake and attractiveness of the bicycle...

Cycling or walking? Determinants of mode choice in the Netherlands

Interest into active modes (i.e. walking and cycling) has increased significantly over the past decades, with governments worldwide ultimately aiming for a modal shift towards active modes. To devise policies that promote this goal, understanding the determinants that influence the choice for an active mode is essential. The Netherlands is...

Is active travel part of a healthy lifestyle? Results from a latent class analysis

Introduction: Behavioral health risk factors are major causes of morbidity and mortality worldwide. The four main risk factors, the so-called SNAP-factors, relate to smoking, nutrition, alcohol consumption and physical inactivity. A consistent finding in health research is that these behaviors tend to cluster together, thereby resulting in...

Insights into factors affecting the combined bicycletransit mode

This paper considers an upcoming, sustainable multimodality: the combination of bicycle and transit. The flexibility of the bicycle combined with the speed and comfort of good transit can be a highly competitive alternative to the car. This study shows that many factors influence the uptake and attractiveness of the bicycletransit combination....

Modelling multimodal transit networks: integration of bus networks with walking and cycling

Demand for (public) transportation is subject to dynamics affected by technological, spatial, societal and demographic aspects. The political environment, together with financial and spatial constraints limit the possibilities to address transit issues arising from growing demand through the construction of new infrastructure. Upgrading of...

Riding performance on a conventional bicycle and a pedelec in low speed exercises: Objective and subjective evaluation of middle-aged and older persons

This study investigated cycling performance of middle-aged (30–45 years old; n = 30) versus older (65+ years; n = 31) participants during low-speed tasks for which stabilization skills are known to be important. Additionally, participants’ self-ratings of their cycling skills and performance were assessed. Participants rode once on a...
