Expanded Controller Interface Device Input/Output Capabilities and CID Software Coordination

The controller interface device (CID) is the result of several years of hardware and software development by National Institute for Advanced Transportation Technology (NIATT). This project had two objectives: the first was to expand the capability of the CID for applications where the number of input/output connections limit performance. The second objective was to investigate a new application area for CID technology, developing and testing a prototype to use the CID and CORSIM simulation to test traffic controller compliance to NTCIP communication standards. This final report is made in two parts. The first describes the development of a synchronous data link control (SDLC) interface capability for the CID. The second part discusses the completion of the real-time playback system to test CID timing performance introduced in and is presented in the form of a paper titled: "Real-Time Playback Hardware-in-the-Loop Simulation of Traffic Systems," presented at IECON 2005, 32nd Annual Conference of the IEEE Industrial Electronics Society. This paper discusses the development of a software-controlled embedded system to evaluate the effect of communication latencies in hardware-in-the-loop simulation of traffic systems. The tool uses the CID hardware developed for hardware-in-the-loop simulation with modifications made to the firmware to support real-time playback (RTPB). RTPB simulators have been used in power systems as a cheap alternative to real-time simulators. In some cases RTPB is the only possible simulation method. This paper presents the application of RTPB to traffic simulations using actual traffic controller hardware.
