Abstract: Provided is a system for improving road safety of a vehicle. The system comprises a central management platform for managing a plurality of network cooperation engine (NCE) modules. Each NCE module manages a plurality of edge gateway devices (EGWs) which are each located in a respective defined geographical area of limited size. Each EGW communicates with multiple roadside units (RSUs) in its area and exchanges real-time and low latency information with said RSUs and with any vehicle on-board data processing units (ICGWs) in vehicles presently within its area. Each ICGW is adapted to be installable in a vehicle. The ICGW is configured to receive real-time data from one or more on-board vehicle modules. The ICGW is also configured to receive data from its EGW and the RSUs which are themselves configured to receive data from a plurality of sources located within said defined geographical area and to transmit said received data and/or data derived from said received data to said ICGW. The ICGW is configured to process data to autonomously determine any one or more of: a threat to the vehicle; an alert to be issued; and a control action to be implemented for the vehicle. A size of the defined geographical area may be selected such as to enable data from said EGW and/or RSUs to be transmitted to said ICGW in real-time or at least at or less than a first, low level of latency.
