Abstract: A vehicle messaging transmission method, a vehicle messaging transmitter, a vehicle messaging reception method, a vehicle messaging receiver, an infrastructure node method, and infrastructure node and computer program products are disclosed. The vehicle messaging transmission method, comprises: detecting a vehicle event; and transmitting both a vehicle-to-vehicle message over a vehicle-to-vehicle radio link, the vehicle-to-vehicle message identifying the vehicle event and a vehicle-to-infrastructure message over a vehicle-to-infrastructure radio link, the vehicle-to-infrastructure message identifying the vehicle event. In this way, rather than periodically transmitting location messages, instead messages are only transmitted when a particular event occurs. This helps to reduce the volume of messages since the messages are only transmitted when an event occurs. Also transmitting a vehicle-to-vehicle message enables messages to be transmitted quickly, with reduced latency.
