Analysis and Validation of Historical Transportation Investment

The North Carolina Department of Transportation (NCDOT) incorporates economic competiveness as one of the criteria for prioritizing transportation projects and uses the Transportation Economic Development Impact System (TREDIS) to quantify the economic impact of capacity expansion highway projects as part of project prioritization. This proposal presents a project involving structured research that will document and quantify the long-term economic impact of major highway expansion projects specifically derived from projects completed as part of the 1989 Highway Trust Fund Act. The proposed study will provide NCDOT with these deliverables: (1) Evidence-based case studies associated with past Highway Trust Fund projects that helps demonstrate their economic benefits and impacts and communicate them to primary stakeholders of NCDOT; and (2) An ability for NCDOT to submit case studies to the American Association of State Highway and Transportation Officials' (AASHTO’s) new EconWorks initiative. EconWorks will become a national repository for case studies (replacing or exceeding the Strategic Highway Research Program's (SHRP’s) Transportation Project Impact Case Studies (TPICS) site) & potentially a more data rich analysis for states to draw from, thereby increasing the national stature and recognition of the transportation investment work being done in NC.
