NEMA NTCIP 1209 V 02:2014

Communication between an ITS Management Center or portable computer and a Transportation Sensor System (TSS) is accomplished by using NTCIP Application Layer services to convey requests to access or modify values of TSS data elements resident in the TSS via an NTCIP network. An NTCIP message consists of a specific Application Layer service and a set of data elements. An NTCIP message may be conveyed using any NTCIP defined class of service that has been specified to be compatible with the Simple Transportation Management Framework (STMF). The scope of NTCIP 1209 v02 is limited to the functionality related to TSS within a transportation environment. NTCIP 1209 v02 defines data elements that are specific to TSS and also defines standardized data element groups that can be used for conformance statements. The limits and descriptions of the parameters are established to give the user maximum flexibility to operate TSS that either existed when NTCIP 1209 v02 was developed or may exist in the future.
