ISO TR 4286-2021 pdf free download – Intelligent transport systems — Use cases for sharing of probe data.
This document describes various use cases for the sharing of probe vehicle data as a commonplatform for smart city instantiation.When modernizing a city towards a smart city, it is necessaryfor information flows across various fields, such as transportation,healthcare, energy, water andother government services, to be effectively managed and shared. Despite efforts from many cities,integrating all databases related to all services has proven to be a cumbersome task.One challengeis the lack of a systematic way that can be modelled for data sharing.The lTS data sharing model forvehicle probe data can serve as the basis for instigating this type of work. To elaborate how vehicleprobe data work can be applied to achieve this objective, this document:
– gathers use cases and examples of vehicle probe data sharing around the world, and
– provides use cases for data sharing that are appropriate for smart city ITS mobility solutions.By examining these use cases and current and planned data sharing practices around the world, thisdocument demonstrates how this mechanism can help implement many smart city applications.
This document also shows that by combining the vehicle probe data with roadside sensor data, andother important public and private data sources, the services can be operated more effectively.
Data collection methods and data or information provisioning are beyond the scope this document.Specifically, this document does not describe items related to the vehicle probe data collection nor thevehicle probe data provision activities as specified by other existing standards such as ISO 19414.

As shown in Figure 1, the service provider, through the pre-provision process, requests vehicle data from a vehicle and the vehicle provides vehicle data to the service provider accordingly. The service provider stores data into the database and executes application services with the support of the database, and the processed information of those services are provided back to the vehicle. Likewise, the service provider can exchange information with road authorities. In some cases, the service provider can collect probe data from the vehicle through a road authority. In such a case, the vehicle data are collected by roadside sensors and passed to the road authority. Data collected through other roadside sensors can also be collected by the road authority. The road authority can then aggregate those data and send them to the service provider. In return, the service provider can provide the processed valuable information to the road authority. 4.2 Concept of data sharing of vehicle probe data Although a common database can help the service provider improve its operational efficiency in its service realm, the real benefit to a probe vehicle system can be further amplified only if multiple probe databases in the probe vehicle system are also shared. Figure 2 provides a conceptual view of how multiple databases are shared in a probe vehicle system. The databases shown on the left are the ones associated with each service provider, such as probe service and other services.ISO TR 4286 pdf download.
