V2I (vehicle-to-infrastructure) communication

Our way to prepare you for the future

Vehicles are becoming ever more connected. Cars will talk to other cars (V2V), to transport infrastructure (V2I) such as traffic lights, to smartphone-wearing pedestrians and cyclists, and to data centres via cellular networks. V2I (Vehicle to Infrastructure) communication uses technology that allows vehicles to communicate  with the traffic system around them that may affect the vehicle, and vice versa. The main motivations for V2I are road safety, traffic efficiency, and energy savings.

One communication technology that is standardized within Europe by the automotive industry is the short range communication standard Wifi-11p. This form of cooperative communication can be compared to traditional Wifi, with very fast set-up times. This standard is used between cars to e.g. share breaking information. Road side infrastructure, such as traffic lights and variable message signs, can be equipped with Road Side Units (RSU’s) to communicate with these vehicles using the same standard. Road users benefit by receiving information on e.g. time-to-red and time-to-green, speed advice and general messages, like warning for road works, icy roads or reindeers. Road authorities benefit by receiving more granular data from individual vehicles on the road. This data is used to predict and improve flow, road safety and emission. Some of these services can also be provided to smart phones in vehicles, connected via cellular communication, extending the user base.

Dynniq’s connected and cooperative service propositions

Dynniq offers road authorities Road Side Units (RSU’s) to communicate with cooperative traffic. RSU’s can be managed with Dynniq’s Connected and Cooperative Services Platform (CCSP). CCSP facilitates the geographical information flow between RSU’s and traffic management centres. Messages from traffic management centers are sent to the appropriate RSU’s, so the right users are receiving warning messages at the right moment, e.g. to avoid head-end collision or roadworks. The other way around CCSP receives data from vehicles that can be shared across other RSU’s or traffic management. An example use case is a stopped emergency vehicle that transmits it’s position to CCSP via a nearby RSU. CCSP propagates this information to other RSU’s in the surrounding. In vehicle, information is communicated via an On Board Unit with Wifi-11p or cellular apps.

Proven eco-system

Dynniq is involved in various European projects on this theme from the early start. From standardization, and implementation of reference architecture, recent projects where Dynniq is involved are now targeted at a proven production-ready international cooperative corridor eco-system. These projects, such as Intercor, Aurora and C-Mobile cover vendor equipment interoperability, security and use cases.
