Functional ObjectDescriptionUser Defined
ITS Communications Support'ITS Communications Support' provides means to send and receive messages to and from other ITS Objects. It provides mechanisms for scheduling and prioritizing communications traffic. It may also provide relay functions.False
ITS Management Support'ITS Management Support' provides management of the ITS Object. This includes management of regulatory information and policies, management of application processes, management of communication system configuration and update management, communications interfaces, protocol–specific techniques to ensure interoperability such as service advertisements, communications congestion management and interference management, local device states and communications information, billing management, fault management, service level and performance monitoring.False
ITS Security Support'ITS Security Support' provides communications and system security functions to the ITS Object, including privacy protection functions. It may include firewall, intrusion management, authentication, authorization, profile management, identity management, cryptographic key management. It may include a hardware security module and security management information base.False
TMC Intersection Safety'TMC Intersection Safety' controls and monitors RSEs that support stop sign, red light, and mixed use crossing violations. It configures the RSEs for the current intersection geometry and traffic signal control equipment at the intersection. Information that is currently being communicated to passing vehicles and the operational status of the field equipment is monitored by this application. The operational status of the field equipment is reported to operations personnel.False
