Evaluation of Roadway Efficiency (EVE)
EVE is an information database that defines current and future highway needs. It has the ability to prioritize projects in a five-year time frame by parameters such as Average Daily Traffic (ADT), volume-capacity (v/c) ratios, Level of Service (LOS), economic justification and degree of hazard. As specific project prioritization criteria are defined by the Long Range Planning process, these criteria will be integrated with the statewide collection of data, analysis, and mapping of roadway deficiencies and practical application process to streamline use. The Prime Study Needs Assessments are supported by the Evaluation of Roadway Efficiency (EVE) Program, focusing on developing system performance measures, project economic viability; expanding project prioritization criteria, and transportation systems scenario development. EVE data system is responsible for collecting and maintaining Level of Service and ADT (current and forecasted traffic data) using information from the Department’s Tennessee Roadway Information Management System (TRIMS) database.
