Contributory Factors Affecting Willingness to Use Shared Autonomous Vehicles in Greece

Abstract

The aim of this paper is to investigate the factors that affect willingness to use Shared Autonomous Vehicles in Greece. To achieve this goal, an on-line questionnaire survey was designed and distributed via various different channels, with a final sample size of 164 questionnaires. The designed questionnaire explored modal choice through a stated preference experiment, while revealed preferences related travel characteristics, traveler perceptions and attitudes, as well as demographic characteristics were also collected. Statistical analysis was performed through the design of multinomial logit models, with the dependent variable being modal choice. Results indicated several contributory factors including travel cost, travel time, trip purpose, transport mode, preferences and attitudes considering privacy and flexibility, technology familiarisation and traveller age and income. The results of this work can be utilized for the design of targeted policies towards promoting the use of shared autonomous vehicles in the future.
