Abstract
Autonomous vehicle (AV) is an innovative transport option that has the potential to disrupt all industries tied to transportation systems. The advent of AV technology will bring a novel on-demand mobility pattern such as shared autonomous vehicle (SAV). To promote AV technology, it is important to understand which factors influence travelers’ intention to use AVs and SAVs. This paper collected literature from databases such as Scopus, Web of Science and ScienceDirect, and made a systematic review. The study aims to explore the determinants that influence travelers’ behavioral intentions towards use AVs and SAVs based on an extended version of the theory of planned behavior, which incorporates knowledge and perceived risk. This study was tested empirically using a valid survey sample collected from 906 respondents in China. Structural equation model was conducted to investigate the predictors of intentions to use AVs and SAVs. Results showed that knowledge about AV technology and perceived risk are the two main potential obstacles for travelers to use AVs and SAVs. Attitude significantly affects AVs and SAV choice intentions. Subjective norm is the most critical factor affecting the travelers’ intention to use AVs. Perceived behavioral control potentially stymie the travelers’ intention to use SAVs. The findings will enhance the understanding of travelers’ choice motivation from psychological and service perspectives, and provide data support for governments and companies in improving travel management strategies and product services.
Highlights
Traffic safety and congestion are major transportation issues in many areas around the world
New forms of mobility mode are entering the market, which will have a huge impact on travel mode choice in the future transportation system
By incorporating knowledge and perceived risk, this study has proposed and empirically tested an extended theory of planned behavior (TPB) model to understand traveler’ behavioral intention to use Autonomous vehicle (AV) and shared autonomous vehicle (SAV)
Summary
Traffic safety and congestion are major transportation issues in many areas around the world. One of the largest costs of vehicle ownership is the depreciation cost, the value of the car could be lost over time It will be years before widespread adoption of AV technology, some studies suggested clearly that AV technology will have a devastating impact on traditional transportation systems. With the popularity of AV technology and the increase in AV penetration on the road, AVs and SAVs could dramatically reduce congestion caused by human driving behavior and improve the road transportation efficiency [10,14,15]. The analysis of travelers’ choice is an important issue for policymakers, who might decide to implement specific interventions to stimulate the diffusion of innovative and sustainable technology
