4 Use cases for the probe vehicle systems data sharing framework 4.1 The conceptual framework for vehicle probe system data sharing Various probe data systems are deployed and successfully operated by service providers independently. However, most likely, the vehicle probe data collected by one ITS systems can only be used for a specific application by the service provider and are not shared among other applications. In exploiting applications and services for a smart city, such data cannot be used effectively, for the purpose of solving smart city mobility issues, for example. Part of the issue is that the service providers often work in their own specific application silos and fail to see the value of data sharing from a holistic viewpoint. It is recommended that the vehicle probe data be shared among stakeholders; this sharing could support various potential fields of services for smart city service applications via a common database. Ideally, all the data in each application supporting a smart city ought to be exchanged through all fields of services with a common format. However, this is not feasible as most of the vehicle probe data systems in place are deployed at different times and provided by different vendors. In the case of the probe vehicle system, for example, aside from the data gathered from certain applications or services which do follow a set of standards, most of the data collected requires transformation or conversion to ensure data interoperability. From a data access efficiency viewpoint, the best place to implement these data conversions is at the common database.
Although data interoperability is essential when adopting the common database for probe data, data ownership and privacy protection need to be taken into consideration as high priority issues. Probe data might need to be gathered from sources applying proprietary means. Some service providers can consider that such data bear much value and can be reluctant to grant the access to those data freely. Furthermore, some probe data can be associated with an individual and needs to be specially protected according to personal privacy protection regulations. This document describes useful use cases for sharing vehicle probe data and provides useful examples currently used and planned around the world. This document provides role model descriptions of data sharing only, and does not cover data collection, nor data provision. The conceptual framework of the vehicle probe system, as shown in Figure 1 below, depicts the relations among stakeholders, such as a service provider, vehicles including connected and automated vehicles (CAV), roadside systems and the roadside operation authorities. The key is to have a common database so that all the service data, regardless of their origins can be fed and stored in the common database. Since the implementation of such a framework for probe data systems can vary, the framework depicted in Figure 1 is for reference only and cannot include all the stakeholders and outlines of their roles.
