N2 - Shared autonomous vehicles (SAVs) are projected by experts to transform transportation, but consumers will decide whether they are actually a success. This study aims to identify the perceptions, attitudes, concerns, and preferences of people who experienced a pilot demonstration of SAVs that had been integrated with current transportation systems. It applies ordinal logistic regression to analyze the survey data collected from the users and nonusers of the SAV service and analyzes the results of interviews conducted in the post-deployment phase of the project. The results of the survey analysis indicate that the ease of using AVs, which, among other things, eliminates the need for parking, is positively correlated with individuals' willingness to use SAVs. Conversely, concerns and confusion about having both drivers and AVs on the street are negatively correlated with individuals' willingness to use SAVs. Virtual interviews with users and nonusers in the post-deployment phase of the project revealed that waiting time, pickup and drop-off locations, and the inability of AVs to make tight turns at intersections were major concerns for SAV service users. This study provides insights into the perceptions and attitudes of those who do and do not use the service and identifies strategies to successfully integrate an SAV service with an existing transportation network to enhance SAV operations.
