Yunex Traffic Onboard Unit (OBU)

The Yunex Traffic OBU2X is a hybrid V2X communication unit for vehicles. It enables the integration of vehicles into cooperative ITS systems (C-ITS). In combination with Roadside Units (RSUs) messages can be exchanged bidirectionally in real-time via DSRC or C-V2X between vehicles and infrastructure. Where no RSUs are available a cellular communication via 4G LTE to traffic management central is used to send prioritization requests from vehicle to traffic controller. With this approach the advantages of both technologies can be combined: robust, free and standardized real-time communication via V2X and long-range communication via LTE for areas without full RSU coverage.

Via the OBU2X public transport and emergency vehicles can be prioritized at the intersection and receive information about the priority response. At the same time other C-ITS use cases can be supported without the need for additional equipment. For example, information about the current signal phase and timing (SPaT) can be used to improve the efficiency of the prioritization. In the future also hazard alerts can be sent and received to increase the safety for pedestrians and bicyclists.
