Left: A stopped Blue Bird school bus broadcasts its stop-arm status to an approaching Audi e-Tron vehicle to notify the driver that children are currently entering or exiting the school bus.


Right: An Audi e-Tron driver enters an active school zone with school zone safety beacons equipped with a road side unit (RSU) that sends a direct, low-latency signal to the vehicle with embedded C-V2X technology. When received, a BSM (basic safety message) notification on the vehicle dashboard indicates an area where school children are present and to slow down.


driver’s dashboard as school buses communicate to pas- senger cars of school bus stops. Qualcomm’s C-V2X solutions allow vehicles to com-


municate directly with other vehicles (vehicle-to-vehicle or V2V), with road infrastructure (vehicle-to-infrastruc- ture or V2I) and with pedestrians and other vulnerable road users (vehicle-to-pedestrian or V2P). Vehicle-to-Cloud (V2C) and Vehicle-to-Network serve as


complementary forms of communication already in most new vehicles for increased awareness, Misner shared. “Delivering dependable, real-time information [is]


critical for safety applications, C-V2X supports highly accurate, time-critical alerts that help make all road users more detectable,” he said. “When integrated into road- side units (RSUs), vehicles and even school buses, C-V2X technology can help address the unique safety needs of VRUs and facilitate safety applications designed to reduce the number of injuries and fatalities on the road.” Traffic Signal Preemption and Traffic Signal Priority


are two separate use cases supported by Qualcomm’s C-V2X technology and partners like Applied Informa- tion, Misener noted.
