VII System Architecture Overview June 2006
VII System Architecture The VII System consists of multiple Sub-systems developed by both Public and Private Entities that will ultimately enable functionality for public and private Services
Communications Transportation of data between a vehicle and a network user, optionally supporting preservation of communication session as vehicle move between RSEs. RSE Information Lookup Provide RSE information, such as location or current service offerings to network users. Management Monitoring, configuration and control using network management systems and services. Security Provides for managed security controls and mechanisms. Positioning Utilizes multiple sources to develop accurate vehicle positioning System Time Utilizes GPS (Stratum-1) timing source for system components facilitating synchronization. Probe Data Distribution Distribute vehicle generated probe data to subscribing network users Advisory Message Distribution Distribute geographically-focused advisory messages to passing vehicles Map Element Distribution Distribute local intersection and road section maps to passing vehicles is support of safety applications. Position Correction Distribution Distribute position correction information to passing vehicles in support of safety applications. Roadside Infrastructure Support Interface with signal controllers for distribution of signal phase and timing information to passing vehicles in support of safety applications. Interface with roadside sensors to forward information to network user or to distribute advisory messages to passing vehicles. Interface with roadside transaction processing systems.
