“…Although nationally representative surveys provide valuable information about users’ willingness to accept and adopt AVs, individuals should be directly exposed to this emerging technology, to inform their perceptions of the capabilities and limitations of automation [ 5 , 6 , 13 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. While we hope that automation solves our current transportation problems, we want users to have realistic expectations of automation and to calibrate their trust, perceptions, and hesitation with the actual capabilities of the systems.…”

Autonomous Shuttle Operating on Highways and Gravel Roads in Rural America: A Demonstration Study

The safe integration of Automated Driving Systems (ADS) into the nation’s on-road transportation system, particularly in rural areas, could vastly improve overall quality of life for a rapidly growing segment of the US population. This paper describes findings from the first half (i.e., three of six phases) of a demonstration project called “ADS for Rural America”. The goal of this project is to conduct a series of demonstrations that utilizes an autonomous shuttle to show how older adults (≥65 years old) could be transported from their rural homes to other locations in rural areas, as well as an urban center. This paper examines older adults’ perceptions of automation before and after riding in an autonomous shuttle and their ratings of anxiety throughout the ride as they experience particular road types and maneuvers. After riding in the shuttle, older adults expressed decreased suspicion, increased trust, and increased reliability of ADS compared to baseline. Older adults reported low levels of anxiety during the 90 min ride in the shuttle. To promote the adoption and acceptance of ADS, older adults should be exposed to this technology.

“…It is also widely believed that such intentions are somewhat associated with subsequent behavioral preferences [29,36]. The Theory of Planned Behavior (TPB) [37], the Norm Activation Theory (NAT) [38], the New Ecological Paradigm (NEP) [39][40][41][42], and the Value-Belief-Norm (VBN) theory put forward by [43] serve as the theoretical foundation for this study, as discussed below.…”

“…It proposes three variables for the prediction of behavior, namely (i) Personal Norm (PN) or moral obligation, (ii) Awareness of Consequences (AC), and (iii) Ascription of Responsibility (AR), which denotes the feeling of responsibility for negative behavioral consequences on society and the environment. The NEP was conceptualized [39][40][41][42] in response to the issue regarding the detrimental effects of human activities on the fragile biosphere. Similarly, the VBN theory was postulated by [43], who focused on several values related to environmental behaviors, such as self-regard and self-sacrifice toward other humans, the environment, and the planet, which all play a role in driving pro-environmental human behaviors.…”

Studying the Joint Effects of Perceived Service Quality, Perceived Benefits, and Environmental Concerns in Sustainable Travel Behavior: Extending the TPB

2023

The importance of the sustainability concept has gained increasing attention from scholars and practitioners. In this context, the aim of this study was to examine the determinants of intention to continue to use the new Metro in Qatar, which is considered a sustainable mode of travel. Therefore, in this paper, a special attention was paid to certain variables, such as environmental concern, perceived quality, and perceived benefits. A quantitative method approach was employed, in which data were collected based on self-administered questionnaires. A total of 1334 Qatar residents responded to the survey questionnaire, and Structural Equation Modeling (SEM) was used for hypothesis testing. The results confirmed the direct effects of perceived behavioral control, social influence, and attitudes on the intention of residents to continue to use the Metro network in their travel. Moreover, perceived behavioral control was found to play a mediating role, enhancing the indirect relationship between perceived benefits and intention to continue to use the Metro network. More importantly, environmental concerns significantly and positively affected the attitudes and perceived behavioral control of travelers; furthermore, these variables presented a mediated influence—through service quality—on the intention to continue to use the Metro network. This study enriched the sustainability behavior literature by examining the influences of crucial factors. Thus, this study is considered of great value for policy-makers who hope to maximize the awareness level of environmental sustainability among the population, in order to encourage them to embrace changes in their lifestyle towards becoming more environmentally responsible.

“…Companies like Tesla and Waymo have shown some really impressive examples of autonomous driving in real road conditions. Waymo has already created a fleet of vehicles that operate as taxis in some US cities [14], WeRide did the same in Guangzhou, China [4] and Tesla has announced that is launching a similar service soon.…”
