Jahanshahi, Danial (author), Costello, Seósamh B. (author), Dirks, Kim Natasha (author), van Wee, G.P. (author)This study explores the effectiveness of cycling initiatives in encouraging bicycle usage, and the relationship with sociodemographic characteristics amongst residents of the multi-cultural city of Auckland, New Zealand. The study considered regular cyclists, potential cyclists, as well as non-cyclists across demographic groups, including age,...journal article 2023

van Wee, G.P. (author), de Jong, Tom (author)This paper explores to what extent inequalities in travel times, measured via the Gini index, depend on the spatial scale at which (average) travel times are measured. By using the new concept of Dedicated Accessibility Points, for the Netherlands we calculated average travel times at four spatial levels, ranging from virtually individual...journal article 2023

Soghrati Ghasbeh, Sogand (author), Pourmohammadzia, N. (author), Rabbani, Masoud (author)Purpose: This paper aims to address a location-distribution-routing problem for distributing relief commodities during a disaster under uncertainty by creating a multi-stage model that can consider information updates during the disaster. This model aims to create a relief network that chooses distribution centers with the highest value while...journal article 2022

De Graaf, Maartje M.A. (author), Perugia, Giulia (author), Fosch-Villaronga, Eduard (author), Lim, Angelica (author), Broz, F. (author), Short, Elaine Schaertl (author), Neerincx, M.A. (author)Discrimination and bias are pressing issues of many AI and robotics applications. These outcomes may derive from limited datasets that do not fully represent society as a whole or from the AI scientific community's western-male configuration bias. Although being a pressing issue, understanding how robotic systems can replicate and amplify...conference paper 2022

Martínez-Buelvas, Laura (author), Rakotonirainy, Andry (author), Grant-Smith, Deanna (author), Oviedo-Trespalacios, O. (author)Connected and automated vehicles (CAVs) are expected to revolutionise transport worldwide and transform urban life. However, there are many unknowns concerning the impacts of these technologies in terms of sustainability, justice, and safety. It has been suggested that CAVs may exacerbate inequities and safety disparities concerning the...journal article 2022

van Wee, G.P. (author)This discussion paper proposes a conceptual model for the factors influencing ethical concerns regarding accessibility, building on the idea that people should have a minimum level of access to some destinations (founded in the ethical principle of sufficientarianism), and secondly from the idea that differences in levels of accessibility...journal article 2022

Jafino, B.A. (author), Kwakkel, J.H. (author), Klijn, F. (author)To support equitable adaptation planning, quantitative assessments should consider the fairness of the distribution of outcomes to different people. What constitutes a fair distribution, however, is a normative question. In this study, we explore the use of different moral principles drawn from theories of distributive justice to evaluate...journal article 2022

Jafino, B.A. (author)Transport network criticality analyses aim at identifying important segments in a transport network. Such studies are often based on the utilitarian principle, where the criticality of a segment is assessed based on its contribution to the aggregate performance of the transport system. To allow for the use of alternative moral principles, I...journal article 2021

Dixit, M. (author), Chowdhury, S.J. (author), Cats, O. (author), Brands, T. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)Circuity of transit networks, defined as the ratio of network to Euclidean distance traveled from origin to destination stop, has been known to influence travel behavior. In addition to the longer time spent in travel, for networks where fare is based on distance traveled, higher circuity also means higher fare for the same Euclidean distance...journal article 2021

Jafino, B.A. (author), Kwakkel, J.H. (author)To support equitable planning, model-based analyses can be used to explore inequality patterns arising from different scenarios. Scenario discovery is increasingly used to extract insights from ensembles of simulation. Here, we apply two scenario discovery approaches for unraveling inequality patterns and their drivers, with an application to...journal article 2021

Leffler, David (author), Burghout, Wilco (author), Jenelius, Erik (author), Cats, O. (author)The paper develops a simulation model and evaluates fixed versus on-demand operational designs of a station-based automated feeder service. The evaluation considers the operational cost and average passenger level-of-service trade-offs as well as distributional differences in waiting times. Two case studies are used to evaluate such trade...journal article 2021

Rubensson, Isak (author), Susilo, Yusak (author), Cats, O. (author)When Public Transport Administrations propose changes in fare schemes or increased fares, they are often met with concerns regarding the proposed fare schemes fairness. Implicit in these concerns is an understanding of relations governing land use and public transport, impacting equity. In this paper, we use socio-economic statistics of...journal article 2020

Ciullo, A. (author), Kwakkel, J.H. (author), De Bruijn, Karin M. (author), Doorn, N. (author), Klijn, F. (author)Flood risk management decisions in many countries are based on decision-support frameworks which rely on cost-benefit analyses. Such frameworks are seldom informative about the geographical distribution of risk, raising questions on the fairness of the proposed policies. In the present work, we propose a new decision criterion that accounts...journal article 2020

van der Veen, Anne S. (author), Annema, J.A. (author), Martens, Karel (author), van Arem, B. (author), Correia, Gonçalo (author)Equity considerations in transportation planning literature have received increasingly more attention in the previous decades. While there have been theoretical suggestions to base transportation planning methods on the philosophical principle of “sufficientarianism” (whereby everyone is entitled to a minimum level of a good or service), the...journal article 2020

Rubensson, Isak (author), Susilo, Yusak (author), Cats, O. (author)A fair distribution of public transport benefits is a commonly stated goal of agencies and operators of public transport. However, it is less complicated and costly to provide accessibility in some parts of cities and their surroundings than in other parts. Densely populated areas, and areas situated closer to the city center therefore often...journal article 2020

Pangbourne, Kate (author), Mladenović, M. (author), Stead, D. (author), Milakis, D. (author)In this paper we focus on the development of a new service model for accessing transport, namely Mobility as a Service (MaaS) and present one of the first critical analyses of the rhetoric surrounding the concept. One central assumption of one prevalent MaaS conceptualization is that transport services are bundled into service packages for...journal article 2020

Sustainability indicators: Monitoring cross-county water cooperation in the Nzoia river basin, KenyaOnencan, A.M. (author), Enserink, B. (author), van de Walle, B.A. (author)Kenya Water Services Regulatory Board (WASREB) Impact Report indicates a stagnation in water coverage at 55 percent, for the last three years, contrary to the 2015 target of 80 percent. One main reason for the stagnation is weak cross-county cooperation between hydrologically interdependent governments. WASREB has little guidance on what...journal article 2019

Ciullo, A. (author), De Bruijn, Karin M. (author), Kwakkel, J.H. (author), Klijn, F. (author)Rivers typically flow through multiple flood-protected areas which are clearly interconnected, as risk reduction measures taken at one area, e.g. heightening dikes or building flood storage areas, affect risk elsewhere. We call these interconnections 'hydraulic interactions'. The current approach to flood risk management, however, neglects...journal article 2019

Alexander, Meghan (author), Doorn, N. (author), Priest, Sally (author)Legitimacy is widely regarded as a founding principle of ‘good’ and effective governance, yet despite intense academic debate and policy discourse, the concept remains conceptually confusing and poorly articulated in practice. To bridge this gap, this research performed an interpretive thematic analysis of academic scholarship across public...journal article 2017
