On connected infrastructure, roads and vehicles now talking to each other
Digitalization of infrastructure assets will lead to increasingly widespread information exchange between infrastructure and vehicles, and among vehicles. In the initial stage, this dialog will take place mainly as I2V (Infrastructure-to-Vehicle), and then evolve into V2X (Vehicle-to-Everything), allowing communication among vehicles, road infrastructure and any other element that may be part of the interconnected system.
Movyon’s goal is to give freeway operators an active role in developing autonomous driving, so that the road infrastructure can amplify the ability of vehicles to receive and return information, in addition to the information that can be processed by its on-board sensors, with the aim of raising safety and sustainability levels.
The cooperative technologies developed by Movyon enable communication between vehicles and the infrastructure (V2I), exploiting antennas arranged along the freeway to interface with devices on board the vehicles and with traffic control centers. This system allows vehicles to receive information such as the presence of construction sites, queues and accidents, while the infrastructure collects real-time traffic data from vehicles, and then returns it to the traffic monitoring centers.
Antennas are also used to improve precision positioning to ensure that vehicles are always able to maintain the same level of driving automation, a crucial safety-related aspect, especially in areas with poor or no GPS signal (such as tunnels).
Regarding autonomous driving, Movyon collaborates with several research institutes. With the Politecnico di Milano in particular, it has initiated several projects for testing advanced technologies on specially designed autonomous vehicles.
The most recent testing projects include those carried out in open traffic for the purpose of collecting information to verify how the vehicle “reads” the infrastructure, with a particular focus on horizontal and vertical signs. This serves to identify the technologies and actions needed to optimize interaction between vehicles and infrastructure.

MOVYON innovation on board the solution
I2V-V2I with 5G
MOVYON is experimenting with testing I2V-V2I communication by using an Internet-connected platform, which users can access through their smartphones, possibly 5G. This approach, complementary to other short-range technologies, will allow for maximum scalability and flexibility in its future developments.
C-ITS G5
This technology is based on a European standard derived from the DSRC short range protocol IEEE 802.11.p. It is chosen with a view adopted to maximum achieve the utmost interoperability and close partnership with other interconnected motorway operators: it allows for coexistence with other technologies based on DSRC 5,8 ghz – Electronic Toll Collection – and digital tachograph.
Communication technologies
The V2X communication platform between vehicle and road infrastructure is direct and bi-directional. Setting up a platform allows for processing data sent directly by the RSU or by ASPI systems, and for directing the information packages. The vehicle thus receives the information and sends them it to the car, thanks – for example – to infotainment.
Data collection and aggregation
This solution makes it possible to allow anonymously collecting the driver’s data in anonymous format, then aggregate them inside the traffic control center, which collects information about all vehicles on the road network. Having heterogeneous information results in a competitive edge, especially during the first technological transition phase, where connected vehicles and others will have to coexist, still allowing in any case for the exchange of reliable and safe information.
