Cooperative intelligent transport systems have the potential to increase the benefits of intelligent transport systems (ITS) services and applications. Cooperative ITS is a subset of the overall ITS that communicates and shares information between ITS stations to give advice or take actions with the objective of improving safety, sustainability, efficiency and comfort beyond the scope of ITS.
ISO/TS 19091 defines the message, data structures, and data elements to support exchanges between the roadside equipment and vehicles to address applications to improve safety, mobility and environmental efficiency. In order to verify that the defined messages will satisfy these applications, a systems engineering process has been employed that traces use cases to requirements and requirements to messages and data concepts.
The focus of ISO/TS 19091 is to specify the details of the SPaT, MAP, SSM, and SRM supporting the use cases defined in this document. Adoption of these messages varies by region and their adoption can occur over a significant time period.
Note: ISO/TS 19091 covers the interface between roadside equipment and vehicles. Applications, their internal algorithms, and the logical distribution of application functionality over any specific system architecture does not covered by this document.
ISO/TS 19091 on cooperative ITS V2I and I2V is useful for:
Cooperative-ITS is a remarkable advancement of intelligent transport systems. Numerous cooperative applications are specified that open up new possibilities to make traffic safer, more efficient, and smarter. Technologies are developed and improved to realize and support those new services and applications. To enable those applications, information needs to be reliably communicated between the stationary infrastructure and mobile vehicles.
ISO/TS 19091 describes the use cases for several applications that address safety, mobility, and ecological sustainability. Each use case has information needs that communication between vehicles and the infrastructure they facilitate. It then identifies the information needs for the applications and the requirements to satisfy them. It maps the requirements into data frames and data elements to fulfil the requirements within the specified message set.
ISO/TS 19091 provides you with a connected vehicle alternative for request and status communication without impacting the back office or local intersection operations of priority management.
