This paper presents an approach for developing a Mobility as a Service (MaaS) system architecture under Autonomous Transportation Systems (ATS), which is a new transition from Intelligent Transportation Systems (ITS) with emerging technologies. The concept of ATS is put forward, which aims to integrate all the components and users of the transportation system to achieve self-organizing system operation and autonomous mobility services. To provide a common framework to plan and implement MaaS applications in the context of ATS, it is essential to develop a MaaS architecture that captures the features of ATS. Through the general steps involved in a process in which travelers travel from the origin to the destination, we propose approaches to identify the user needs, the services and key elements of the system. With the basic components, three architecture elements are constructed: functional architecture, logical architecture and physical architecture. The proposed MaaS system architecture design can help the administration make services planning and implement planned services in an organized way, as well as support further technical deployment of mobility services.
