The tool delivered by that project did not consider outsourcing as an option for IMAP expansion. There has been much research over the last ten years that can be applied to yield much improved estimates both of system costs and also of transportation network benefits from well-designed IMAP deployments. Buoyed by this motivation, the NC State/ITRE project team proposes to conduct a thorough review of the state of the practice and well as applicable research to provide new methodologies implemented in an accompanying computational engine that will enable NCDOT to conduct accurate assessments of IMAP program costs and benefits, including evaluation of public and private delivery of service options, and to conduct selection and prioritization of routes for IMAP system expansion
