New article: Stay local or go regional? Urban form effects on vehicle use at different spatial scales: A theoretical concept and its application to the San Francisco Bay Area

Image
Abstract: This paper explores the respective roles of local and regional characteristics of urban form on vehicle travel. We hypothesize that the effects of urban form on vehicle use at the local and regional levels are complementary, and we introduce the concept of local and regional action spaces, which are defined based on the accessibility of alternative means of transport within an acceptable travel time, to test this hypothesis. Multilevel and ordered logit models are developed for the San Francisco Bay Area to estimate the effects of urban form and socioeconomic characteristics on vehicle kilometers traveled (VKT) and vehicle trip frequency (for work, shopping, and social/recreational purposes). We find that the two urban scale characteristics exert complementary effects on VKT. However, because people in the San Francisco Bay Area display significantly lower VKT in the local than in the regional action space, we conclude that regional-scale inter-ventions would c…

New article: Do people consider an acceptable travel time? Evidence from Berkeley, CA

Abstract: This paper explores the extent to which people identify an acceptable travel time for each trip they want to make and investigates the primary characteristics of this behavioural threshold. We assume that an acceptable travel time is defined through utilitarian processes that are related to cognitive and affective evaluations of travel that develop throughout a person’s lifetime. We apply a mixed methods approach to explore our hypothesis, based on semi-structured in-depth interviews with a stratified, according to commuting mode, random sample of 20 individuals living in Berkeley, CA. Our results support the validity of the acceptable travel time concept and offer (a) initial evidence on its variation to the travel mode and sociodemographic characteristics and (b) insights into people’s perceptions, attitudes, feelings and experiences about their travel. Thus, our results can contribute to a better understanding of individuals’ travel decisions and valuation of…

Guest lecture: Development and implications of automated vehicles (TU Delft Transport Institute 21th May, lecture hall G, CiTG)

Image
Next Thursday, May 21 Maaike Snelder and I will give a presentation about the development and implications of automated vehicles, during the Transport Thursday at the faculty of CiTG. Here is a brief description of the lecture and more info about registration. See you there...! Automated driving is a hot topic worldwide associated with many uncertainties though. When will the first fully automated vehicle hit the market and what will be the subsequent implications for our cities and transport systems? Will there be more or less congestion, will we drive longer or shorter distances, are we going to own or share cars? This lecture will address this type of questions in an interactive way… so please do not forget to bring your phone or laptop with you!
We invite you to attend this guest lecture from 12.30h – 13.30h in CiTG lecture hall G (lunch is included). If you know others who might be interested, please feel free to invite them as well.
Please register at transport(at)tudelft.nl
