“…This is in contrast to previous studies that solicited PwDs' perceptions of AV without a lived experience in an AV (Etminani-Ghasrodashti et al, 2021;Hwang et al, 2020) or included adults with developmental or visual disabilities (Feeley et al, 2020) or physical and visual disabilities (Hwang et al, 2020;Mason et al, 2022). Researchers often incorporate universal design principles to investigate transportation barriers in a heterogeneous sample of PwDs (Etminani-Ghasrodashti et al, 2021;Feeley et al, 2020;Hwang et al, 2020). As observed in this study, an inclusive design approach offers numerous benefits specific to adults with SCI.…”

“…The primary strengths of this study were that the participants' perceptions were assessed with a valid and reliable AVUPS, before and after riding in the AS that operated on public roads with ambient traffic, and the strict inclusion of participants with an SCI. This is in contrast to previous studies that solicited PwDs' perceptions of AV without a lived experience in an AV (Etminani-Ghasrodashti et al, 2021;Hwang et al, 2020) or included adults with developmental or visual disabilities (Feeley et al, 2020) or physical and visual disabilities (Hwang et al, 2020;Mason et al, 2022).

“…Studies have highlighted the importance of shared AV services as a mobility option for older adults and persons with disabilities (PwDs; Fagnant & Kockelman, 2015;Hwang et al, 2020). However, information is starting to emerge pertaining to the perceptions of people with mobility impairments (e.g., SCI, orthopedic injuries) and the use of AS (Etminani-Ghasrodashti et al, 2021;Feeley et al, 2020;Hwang et al, 2020). These studies included heterogeneous samples of PwDs and did not expose these populations to an AV.…”

Individuals with a spinal cord injury (SCI) have challenges using transportation. Autonomous shuttles (ASs), if accessible, may support their transportation needs. This study quantified the perceptions of AS for adults with and without SCI, before and after riding in the AS. We hypothesized that the perceptions of AS for individuals with SCI would improve, by the greatest magnitude, after riding in the AS. This mixed-method quasi-experimental design included 16 adults with SCI and 16 age-matched controls. While there were no differences between the groups, both groups reported having fewer perceived barriers to using AS after riding in the AS ( p = .025). After riding in the AS, both groups stated that the AS must be available, accessible, and affordable if they are to use AS. In conclusion, adults with SCI should experience AS if they are to accept and adopt this mode of transportation.

“…Although in this research the variables influencing the development of AVs in Iran were examined, the findings may be applied to other emerging nations with similar economic and social situations. As most of the existing study on AVs focuses on the public [80], it is advised that the viability of implementing AVs for passengers with diverse mobility and communication demands be investigated [83]. This is particularly crucial for Iran, a nation with a large proportion of elderly [72] and handicapped citizens who have difficulty using the standard public transportation networks now in place [84].…”

Autonomous Vehicle Adoption in Developing Countries: Futurist Insights

et al. 2022

In recent years, research into autonomous vehicles (AVs) has become highly popular in industrialized nations due to their importance in the future success of smart cities. Research on this mobility technology and the critical elements affecting its development in developing countries, however, has been rather limited. This paper aims to shed light on the most influential elements of AV adoption in developing nations. A structural analysis approach is used, based on the primary qualitative data—that was gathered via an expert-opinion poll utilizing the fuzzy Delphi with a snowballing method and engaging 25 experts in the field in two rounds—, in accordance with the tradition of futurist research. The analysis has led to the identification of 11 key factors, from the initial factor pool of 54, affecting AV adoption in the case study context of Iran. The results of the analysis revealed the following conclusions, that fall under the policy and legislation domain, and present the most significant issues impacting AV adoption: (a) Future orientation of government—consistency and of accountability of policies, the long-term vision of the government for developing AVs industry; (b) Managing the international sanctions for foreign investment, and; (c) Funding mega projects to enable AVs. The results indicate that the establishment of legislation and the formulation of government policy regarding the provision of infrastructure, investment, and credit allocation are crucial for the development of AVs in Iran and other developing nations with comparable characteristics.

“…To develop the statements about service attributes, we referred to focus group discussions with members of the university community, people with disabilities, and members of the general public, which were performed before deploying the RAPID SAVs (38). These focus group discussions identified the main preferences and concerns of potential users about the proposed SAV service, including the capacity of the service, trip cost, safety, disability-friendly features of the service, accessibility, and reliability (38,39). To explore the concerns and preferences extracted from the SAV predeployment studies, we asked respondents to evaluate the SAV service features: ease of booking and scheduling SAV rides through the mobile application, waiting time, the convenience of pickup and dropoff locations, ease of boarding, comfort of the seats, climate control, speed of the vehicles, feeling safe in the vehicles, and feeling safe when sharing rides with other passengers.…”

Despite the growing interest in implementing shared autonomous vehicles (SAVs) as a new mobility mode, there is still a lack of methodologies to unpack SAV adoption by individuals after experiencing self-driving vehicles. This study aimed to fill this gap by analyzing data collected from a users’ survey of a self-driving shuttle piloted downtown and on a university campus in Arlington, TX. Employing structural equation modeling, the hypothesized relationships between SAV adoption and key factors were tested. Data analyses indicated that individuals with limited access to a private vehicles, low-income people, young adults, university students, males, and Asians were more likely to ride this new service. Furthermore, results showed that SAV service attributes, including internal and external service performance and usual transportation mode, affected users’ willingness to continue using the service in the future. The study also highlighted the role of trip waiting time, -purpose, and -frequency on SAV adoption. Our model simultaneously considered usual transportation mode and trip frequency as factors that could mediate the role of vehicle ownership on SAV adoption. The results suggested that participants with greater access to a private vehicle were strongly interested in using private vehicles and less likely to use the ridesharing alternative, consequently they less frequently used the piloted SAV. The outcomes from this study are expected to inform planners with advanced knowledge about emerging technology to help them to adjust SAV policies before autonomous vehicle services are fully on the roads.
