OBU OBU-V1 is an onboard telecommunications terminal mounted on vehicles and intended for functioning as part of a data transmission network between vehicles, road infrastructure and intelligent transport system. OBU-V series support both DSRC/ITS-G5 and C-V2X technologies

On-Board Unit (OBU)

Cars equipped with V2X devices (OBU - on-board unit) transmit data about the location and status of their systems to the telecommunications elements of the road infrastructure (RSU - road side unit). The ITS-G5 protocol stack standardized by ETSI transmits data over the air between RSU and OBU. vehicles.
The RSUs analyze the information received from a plurality of vehicles and generate a distribution of warning messages about possible collisions and other incidents. Alerts about potential incidents are also sent to the ITS platform (Intelligent Transport System) to take the necessary actions depending on the incident and collect statistics for individual sections of the road network.
In turn, the ITS platform, based on data entered by operators and data from other systems, generates messages transmitted to the RSU (information about planned road works, information about significant deterioration in weather conditions, information about the operating modes of traffic light objects etc.).
The RSUs sent out warnings to passing vehicles.
