    Abstract: An area alert management system (AAMS) for reducing false alerts in a road management system comprises a map data unit comprising map data for a defined geographical area. The defined geographical area includes at least one roadside unit (RSU) configured to receive data from one or more vehicle on-board data processing units. An alert analysis unit of the AAMS receives vehicle generated alerts. The AAMS includes a static environment data unit comprising static environmental data for said defined geographical area. Upon receiving a vehicle generated alert, the alert analysis unit uses a location associated with the vehicle generated alert to obtain data from any of the map data unit, the static environment data unit or sensor data and determines if the received vehicle generated alert is consistent with the obtained data. If not consistent, the alert is determined as a false alert.

    Abstract: A method for improving road safety of a vehicle in a system having a plurality of communicatively connected roadside units (RSUs) placed within a defined geographical area, each RSU configured to receive data from a plurality of sources located within its respective coverage area forming part of said defined geographical area and to at least transmit the received data and/or data derived from the received data to one or more data processing units located within its coverage area. The method has the steps of: receiving data defining an event E1 occurring within the coverage area of an event RSU; determining a type of the event E1; and based on the type of event E1, communicating data defining the event E1 or data related to the event E1 from the event RSU to one or more selected RSUs from remaining RSUs.

    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.
