This invention introduces a decentralized two-way communication
system (DCS) for vehicles, operated by civilians and authorities, that complements existing Emergency Alert Systems (EAS) systems managed by governmental authorities, and the vehicle Vehicle-to-Everything (V2X) communications. The
system allows vehicle drivers and occupants, pedestrians, authorities and other road users to transmit and receive messages and emergency alerts in between them, as well as to and from infrastructure. The DCS is linked to existing Vehicle Management Systems (VMS), and
software applications for mobile devices. The DCS leverage the vehicle Vehicle-to-Everything (V2X) communication systems, and can be used in different communication embodiments such as: Vehicle-to-Vehicle (V2V); Vehicle-to-Infrastructure (V2I); Vehicle-to-
Pedestrian (V2P); Vehicle-to-Cloud (V2C); and Vehicle-to-Network (V2N). An object of the DCS is to improve road safety, road awareness, sharing road conditions, weather updates, road
hazard updates, emergency alert systems (EAS) and save lives.
