    Public values in the socio-technical construction of autonomous vehicle futures

    Abstract

    This study argues that policymaking guided by public values can help to secure public benefit in technology implementation, for two reasons. Firstly, the emergence and deliberation over plural values can result in more publicly beneficial outcomes; secondly, public values establish the meaningful link between public interest and policy goals. We explore the value bases

    Examining the performance of transit systems in large US metropolitan areas

    Abstract

    The assessment of transport systems has traditionally focused on congestion and ridership as its core performance measures. These perspectives fail to account for the actual service people seek from the transport system—the ability to reach destinations. Recent studies have shifted to focus on accessibility as a performance indicator, but do not address the question

    A new index to assess the situation of subgroups, with an application to public transport disadvantage in US metropolitan areas

    Abstract

    The evaluation of how particular segments of society fare is a common concern in many policy and academic realms, including transportation. The Target group Position Index (TPI) is introduced to assess the relative situation of a target group compared to a larger population. It uses two distinct population-specific benchmarks to determine the relative position of the

    Defining and Implementing a Sufficient Level of Accessibility: What's Stopping Us?

    J Ryan, Karel Martens
    Abstract

    Recent transport equity literature has proposed a sufficientarian approach to transport planning, according to which all individuals would be entitled to a minimum level of accessibility deemed adequate or sufficient. The implementation of this approach would require the adoption of an accessibility standard as a key performance

    Models and the Questions We Ask

    Abstract

    Travel demand modeling has been used as a tool by transportation professionals for defining travel behavior processes and procedures for close to seventy years. With origins tied to the construction of the interstate highway system, our pursuit to understand the connections between human behavior and infrastructure is an under-examined part of transportation planning's

    Social identity and cycling among women: The case of Tel-Aviv-Jaffa

    Abstract

    Through the lens of the Social Identify Theory (Tajfel, 1974), this research aims to understand how social identity affects the perception of cycling as a mode of transport among women from different socio-income backgrounds. Using the case study of Tel-Aviv-Jaffa (Israel), we found that cycling is associated with distinct social categories rather than seen as a 'socially

    Value dimensions of autonomous vehicle implementation through the Ethical Delphi

    Abstract

    Using the Ethical Delphi method, this research seeks to understand how professionals relate to ethical socio-spatial implications of possible widespread autonomous vehicle (AV) deployment in cities and societies, and to distil values that can shape AV futures. First, we sought to understand whether professionals engage in ethical thinking and reasoning regarding AV

    Equity in Accessibility: Moving From Disparity to Insufficiency Analyses

    Abstract

    Many studies on transport equity have analyzed disparities in access to destinations between different population groups. In this study, we challenge this disparity approach and propose an alternative: analyzing accessibility insufficiencies. We argue that disparity analyses fall short on two accounts. First, they are based on group averages that inherently hide in-group

    Exploring changes in individuals travel behaviour after bus Rapid Transit implementation in Dar es Salaam

    Abstract

    The use of Informal Public Transport (IPT; i.e., minibuses, motorcycles, and tricycles) for activity participation in Dar es Salaam is associated with mobility difficulties, e.g., traffic congestion, unscheduled services, and lack of safety of the journey. The introduction of the Bus Rapid Transit (BRT) in May 2016 aimed at reducing mobility difficulties by improving

    Core versus periphery: Examining the spatial patterns of insufficient accessibility in U.S. metropolitan areas

    Abstract

    Recent transport equity literature suggests that accessibility analyses should move beyond mapping of the uneven patterns of access to opportunities. Instead, this literature proposes a sufficientarian approach, according to which all individuals are entitled to a minimum level of accessibility. In line with this approach, in this paper we ask: “What are the spatial
