Hybrid V2X Communication for Safety-critical Applications

Inhalt:
The exchange of information between road users makes it possible to improve the individual perception of traffic situations and thus increase safety in the traffic area. The transmission of safety-critical information requires reliable technologies that meet the requirements of a dynamic network with highly mobile participants. The two technologies, ITS-G5 and LTE-V2X, are currently available for this purpose. Both have individual advantages and disadvantages. This investigation looks at ways to combine ITS-G5 and LTE-V2X to create a hybrid network that will increase transmission reliability and better meet the requirements of security-critical applications. The investigation was carried out with the help of a simulation environment. The results show that a hybrid network can indeed increase the reliability of transmissions, with the number of hybrid participants supporting both technologies being decisive for effect.
