Mr. John Smith

Job title



The C-MobILE project defines a new European C-ITS Reference Architecture to ease and promote the deployment of C-ITS services throughout Europe in an interoperable, replicable way. This hybrid architecture is taken as the basis in Barcelona to implement and deploy new mobility services to help increase road safety and traffic efficiency, not only in the city, but also in its metropolitan area. As a main innovative point, traditional C-ITS have been adapted to work over cellular communications and offer both existing and new services. This paper gathers all the process followed to offer a group of cellular-based C-ITS services to almost any kind of road users, from passenger cars to VRUs, including public transport and emergency services. As the backbone of that process the Barcelona-specific end-to-end technical implementation (data sources, formats, backend and frontend) is presented and detailed. This becomes the platform where all the specific services are implemented and managed, those being GLOSA, In-Vehicle Signage, Emergency Vehicle Warning, Road Works Warning, Road Hazard Warning, Flexible Infrastructure, Warning System for VRUs, Motorcycle Approaching Indication and Probe Vehicle Data. Such a platform is formed by different, independent data sources (providing different mobility data), a data management module (where all the data is treated and the road events to be notified are generated), a dissemination module (notifying all those events to the users, depending on their location, via cellular communications), and the frontend application, which is the interface between the system and the end-user. The interactions between the different modules and the data flow, including formats, are also detailed. All the services are thought to be deployed in a large-scale context, with many users connected at the same time and events being updated in real-time. Furthermore, and following one of the project main objectives, they are interoperable with all the C-MobILE sites, which means that the end-user app from Barcelona can be taken to cities such as Bordeaux, Bilbao, Copenhagen, Newcastle, Eindhoven, Helmond, Thessaloniki or Vigo, and still provide the services which are active in those locations. Such an interoperability approach is also presented in this paper.
