This repository contains the source code of the Center-To-Center Reference Implementation (C2C RI) Tool. The C2C RI supports efficient deployment of systems using C2C communications by providing a standardized way to verify conformance to C2C standards. The C2C interface may be between two traffic management centers or any two centers that need to coordinate (regionally or locally) the management of a corridor, arterial, incident, event, or more. Currently the C2C RI supports conformance testing for the Institute of Transportation Engineers (ITE) Traffic Management Data Dictionary (TMDD) v3.03c, TMDD v3.03d and TMDD v3.1 standards, and National Transportation Communications for ITS Protocol (NTCIP) 2306 v1.69 Web Services Description Language (WSDL)/Simple Object Access Protocol (SOAP) protocol.
