This document describes a basic role model of smart city mobility monitoring and services by data sharing platform as a common platform for smart city instantiation. It provides a paradigm describing: a) a framework architecture for the provision of a mobility monitoring service b) a description of the concept of operations, and the role models c) a conceptual architecture between actors involved in the provision/receipt of mobility monitoring service applications d) references for the key documents on which the architecture is based e) a taxonomy of the organization of generic procedures. scope is specialized in defining the requirements of the basic role and functional model of service for the introduction of mobility monitoring services including infrastructure facilities to support mobility in urban and rural areas In-vehicle control system is not in scope of this document. This document is describing the scope limited to the mobility monitoring services using physical and digital infrastructure. The physical infrastructure facilities are, for example, battery charging facility, dynamic charging facility for battery electric vehicle, physical infrastructure markings, physical traffic regulation signs, mobility monitoring facility, emergency responding service support facility, traffic operation control centre facility, fee collection service facility such as road usage fee, battery EV charging facility, online reservation and online mobility usage fee payment facility, other infrastructure platform facility to support mobility monitoring services. This document can contribute to the development of future mobility monitoring service business cases other than system service described within this document.
