Software Maintenance Support for Current Generation CID Grant uri icon



  • In 1998, at the request of the Federal Highway Administration, NIATT initiated development of the next generation Controller Interface Device. The CID provides a real time linkage between traffic controllers and FHWA’s CORSIM model, allowing traffic engineers to efficiently test traffic signal timing plans before they are implemented in the field. During the past three years, NIATT students and faculty, working in interdisciplinary teams from electrical, computer, mechanical, and civil engineering, have developed and tested a production prototype version of the CID. The CID was extensively beta tested at twelve sites around the U.S. during spring 2001. As a result of this beta test, NIATT verified that the CID hardware design was sound and stable. NIATT also identified a number of software changes that were required to make the operation of the CID more effective for end users. This direct work with end users, while providing the development of sound tools, has given NIATT students the opportunity to work in practical and realistic engineering environments. NIATT expects to license the CID technology to a traffic control manufacturer in summer 2001, with the release of the CID II to the marketplace in fall 2001.

    This project will provide the resources to maintain and support the three CID software tools and to develop additional software tools to enhance the traffic engineering applications to which the CID can be used.
