NTCIP 2001

Description / Abstract: The Class B Profile Standard establishes a common method of interconnecting ITS field equipment such as traffic controllers and variable message signs (VMS), defines the protocol and procedures for establishing communications between those components, and references common data sets to be used by all such equipment. Its application is intended for equipment sharing a single communications channel or subnetwork (subnet). The Class B Profile is just one part of NTCIP. NTCIP is a suite of protocols and standards that address all different aspects of transportation and traffic control communications. The Class B Profile addresses the need for a common field device communications standard. It establishes a method for interconnecting field devices, defines the protocol and procedures to establish communications link between them, and defines a common set of operation information variables.
