38、ORD NTCIP 1211 v02, this standard, defines the management information base for Signal Control and Prioritization (SCP) Systems. It defines individual parameters that represent the configuration, status, and control information that is unique to an SCP. NTCIP 1211 v02 defines a set of objects for use
39、 in controlling traffic signal systems in priority applications. NTCIP 1211 v02 provides definitions of the management information related to Signal Control and Prioritization (SCP). SCP management information includes individual parameters that represent the configuration, status, and control infor
40、mation of such a device. It also includes data frames and message sets of these parameters and others from different standards to address the operational information exchanges between the devices in a baseline system configuration. NTCIP 1211 v02 defines requirements that are applicable to an NTCIP
41、environment that involves the control of traffic signal controllers. While the term Signal Control and Prioritization implies a logical implementation, the data concepts may be applicable to a physical device. By definition, SCP operates in the context of a “system“ that includes a priority requeste
42、r, such as a transit vehicle, traffic signal controllers, and the management centers that configure and monitor the traffic signal controllers. It, therefore, imposes functional and communications requirements on all of these “system“ components. The following keywords apply to NTCIP 1211 v02: NTCIP
43、, traffic signal control, transit, emergency responder, priority control, prioritization, signal priority. It also defines specific groupings of these parameters and others to address the operational configuration, monitoring, and control of the device/entity in a baseline system configuration. NTCI
44、P 1211 v02 is an NTCIP Device Data Dictionary Standard. NTCIP Device Data Dictionaries Standards formally express management information in terms of objects (data elements, data frames, and messages) for use within NTCIP systems. NTCIP 1211 v02 uses only metric units. For more information about NTCI
45、P standards, visit the NTCIP Web site at http:/www.ntcip.org. There are normative and informative annexes in NTCIP 1211 v02: a) Annex A is normative and contains a Requirements Traceability Matrix (RTM) that traces requirements to the dialogs and data objects used to fulfill it. b) Annex B is inform
46、ative and contains the object tree showing the major nodes of the SCP object structure within the Global object tree. c) Annex C is normative and (in a future version) is intended to contain the test procedures associated with the user needs, functional requirements, dialogs, and objects defined in
47、NTCIP 1211 v02. d) Annex D is informative and contains each of the major revisions and changes provided for between NTCIP 1211 v02, and its predecessor, NTCIP 1211 v01. e) Annex E is informative and documents user requests that were not included in NTCIP 1211 v02. f) Annex F is informative and provi
48、des a tutorial on SCP and provides examples on how a typical SCP system may work. g) Annex G is normative and contains the definitions for the Generic SNMP interface including the definitions to perform GET, SET, GET NEXT commands. These definitions may to be moved to a different NTCIP standard at a
49、 future date, because this content is applicable to all device-specific NTCIP standards. h) Annex H is normative and serves as a placeholder for systems engineering descriptions that may be moved to a different NTCIP standard at a future date, because this content is applicable to all device-specific NTCIP standards. 2014 AASHTO / ITE / NEMA Do Not Copy Without Written Permission NTCIP 1211 v02.24 Page ii User Comment Instructions The term “User Comment” includes any type of written inquiry, comment, question, or proposed revision, from an individual person or organization,
