Overview

The National Transportation Communications for Intelligent Transportation System (ITS) Protocol (NTCIP) is a family of standards that provides both the rules for communicating (called protocols) and the vocabulary (called objects) necessary to allow electronic traffic control equipment from different manufacturers to operate with each other as a system. The NTCIP is the first set of standards for the transportation industry that allows transportation systems to be built using a "mix and match" approach with equipment from different manufacturers. Therefore, NTCIP standards reduce the need for reliance on specific equipment vendors and customized one-of-a-kind software. To assure both manufacturer and user community support, NTCIP is a joint product of the National Electronics Manufacturers Association (NEMA), the American Association of State Highway and Transportation Officials (AASHTO), and the Institute of Transportation Engineers (ITE). More information concerning the NTCIP family of standards and their related documents is available in the NTCIP 9001 - NTCIP Guide, available on-line at (www.ntcip.org).

Human communications relies on a vocabulary of words, each defined with a fixed meaning and spelling that are understood by the members of the conversation group. Computers have a similar vocabulary, called "objects" in the NTCIP standards. These objects define all possible commands, responses and information that may be exchanged among microprocessor-controlled electronic equipment, traffic management systems (which could include central computers housed in a center or portable computers, e.g. laptops), and by extension, their human operators. The NTCIP groups these objects by subject material (e.g., closed circuit television systems) and calls these groupings "object definitions." The objects defined in this standard allow an operator to command closed circuit television (CCTV) systems to do something and verify that the camera has accomplished the command.

What are these standards for?

This standard, NTCIP 1205 - Object Definitions for Closed Circuit Television (CCTV) Camera Control, provides the vocabulary - commands, responses and information - necessary for traffic management and operations personnel to control, manage, and monitor cameras, lenses and pan/tilt units. This standard contains object definitions to support the functionality of these devices as used for transportation and traffic monitoring applications. The standard includes conformance group requirements and conformance statements to support compliance with the standard.

Who uses them?

This standard, NTCIP 1205 - Object Definitions for Closed Circuit Television (CCTV) Camera Control, should be used by transportation and traffic engineers involved with the design, specification, selection, procurement and installation, operation, and maintenance of closed circuit television systems and components. ITS product hardware and software designers and application developers, particularly those involved in the development of traffic management systems, should find this standard especially relevant to their efforts.

How are they used?

This standard, NTCIP 1205 - Object Definitions for Closed Circuit Television (CCTV) Camera Control, defines a vocabulary of "objects" used to assure that the transportation management center computer-based devices, and closed circuit television systems "speak" a common language. A message must be understood by the device it was intended for, and equally important, it must not be misunderstood or misinterpreted by another device on the same network. Object definitions unambiguously define the content, terminology, units and format of commands, responses and information affecting communications with closed circuit television systems.

This standard must be used with one of the NTCIP communications profiles (see related NTCIP documents below) which provide the communications channel for information transfer between devices. It must be used with the NTCIP Global Object Definitions (NTCIP 1201), which provides the glossary of common object definitions used by multiple NTCIP devices.

Scope

Communications between a transportation management center’s central computer and closed circuit television systems are accomplished by using the objects defined in NTCIP 1205 - Object Definitions for Closed Circuit Television (CCTV) Camera Control. These objects define the information, commands and responses that must be understood by the devices at both ends of the communications channel.
