Resource provisioning, orchestration of heterogeneous facilities, life-cycle management, and task offloading are all open research topics that need fog/edge computing models. Managing a fog/edge orchestration framework, such as is done within the RAINBOW project, enables the creation of new application schemas in a variety of fields. Politecnico di Torino, Links Foundation Lab and CRF Lab collaborated on a safety vehicular application through an Urban Mobility Demonstrator (UMD) use case to test the RAINBOW framework in an automotive environment.

Using the RAINBOW orchestration capabilities, a Road Side Unit (RSU) with a camera can best manage the resources (e.g., bandwidth, power consumption, video resolution, etc.) required to run a combination of computer vision and artificial intelligence algorithms to detect the presence of animals on the road. When a road hazard is recognized, the RSU creates and transmits an alert message to nearby vehicles as well as throughout the network. Messages transmitted this way across the network are controlled by a cloud Broker node, which forwards them to cars entering the hazard region to warn them of the imminent risk.

In addition to the proper execution of all the mentioned procedures, Politecnico di Torino created an online platform for event visualization in a map environment called City Aggregator as a project’s main output. Following the management by the cloud Broker node of all Vehicle-to-Network (V2N) communications, the City Aggregator platform can display live vehicle movements in a map visualization environment, as illustrated in the featured image. Furthermore, when the RSU transmits an alert message to the cloud Broker, the hazard regions are depicted on the City Aggregator urban map, as seen in the Figure 1.

In the context of traffic management applications, online platform objects for event representation in a map environment, such as the City Aggregator, play a vital role. Traffic conditions, roadworks, vehicle accidents, street closures, and other mobility events may all be easily transmitted through the network by info-mobility agencies. Notifications produced in this manner may be controlled by a cloud node and shown on an online platform, allowing the driver to benefit from an integrated mobility service.
