Abstract: A backend for a hazard detection system comprising: a processor; and a memory in communication with the processor, the memory storing a set of instructions. The set of instructions, when accessed and executed by the processor, cause the processor to: receive vehicle and/or driver data from a vehicle, evaluate the received vehicle and/or driver data, use the evaluation as a basis for detecting a hazard in road traffic, and send the information about the detected hazard to at least one vehicle to warn said vehicle about the hazard.

Abstract: A method for selectively transmitting data from a transmitter to a receiver in a non-railbound land vehicle comprises, at the receiver end, selecting at least one geographical region. In this case, a geographical region corresponds to a limited area on a map. After the at least one region has been selected, a request is transmitted to the transmitter to transmit data relating to the at least one selected geographical region, and finally a data transmission initiated by the transmitter in response to the request is received. The data relating to the at least one selected geographical region contain, in particular, information relating to a traffic route infrastructure in the geographical region, which information is valid for a limited period or for a longer time.
