ISO TS 5255-1:2022 pdf download – Intelligent transport systems — Low- speed automated driving system (LSADS) service — Part 1: Role and functional model.
7 Role and functional model 7.1 Objective This clause describes a generic role and functional model for the provision of ITS service applications for LSADS services. It explains the general concept of role and functional model operations. It also provides a definition for the role and functional model and the elaboration of the model at a conceptual level. 7.2 National variations The definition of what comprises an ITS service application is an issue for national decision and can vary from country to country. The instantiation of interoperable on-board platforms (or nomadic devices such as smart phones) for ITS service application with common features is ideal but varies between countries, as does the provision of services. It is possible that certain countries will mandate the use of such a platform, while others will offer it as an option to meet the requirements of the ITS service application with minimum administration and paperwork (providing a good business case for operators to fit and use the equipment). Certain countries might implement a single, government- operated, -controlled, or -contracted service provider, which will be the single communication manager between the user and the service. Other countries might provide a market-based solution with multiple service providers competing for the business of vehicle operators. 7.3 Basic role model The role model concept defined in ISO/TR 4445 shall be considered as baseline document. Figure 1 shows the basic role model for ITS service application for smart cities.
7.4.1 Role and functional model options For the requirements of the role and functional model, it needs to be possible for an LSADS service application user to use the services of different service providers in different geographical areas, or for different services to be provided within the same geographical area. In these circumstances, where there is a market of competing service providers, it is likely that the solution will be for the user to choose a single service provider who will provide and maintain the LSADS service application on a nomadic device (such as a smart phone) and who will deliver to the user all services to which that user chooses to subscribe. Other options are possible, but should be able to support the peer conceptual role and functional model. 7.4.2? Certification? of? service? providers As determined by the regulator, the LSADS service provider will need to be certified by the regulator, and so some form of certification authority (regulatory) role forms an essential part of the role and functional model. However, the role can and will be instantiated differently by different jurisdictions. LSAD vehicle inspection and certification is performed by certain parties, taking into consideration regional authority-defined regulations.
