Estimating the Life-Cycle Cost of Intersection Designs

Jeudi, 11 Février, 2016 - 16:30

TRB’s National Cooperative Highway Research Program (NCHRP ) Web-Only Document 220: Estimating the Life-Cycle Cost of Intersection Designs describes the Life-Cycle Cost Estimation Tool (LCCET). The LCCET spreadsheet allows users to compare alternative intersection designs based on initial construction costs, ongoing maintenance and operations costs, operational efficiencies for a variety of modes, safety effects, and emissions. Alternative designs include roundabouts and traditional intersections using stop signs and traffic signals. Use of the tool is designed to help provide a consistent approach to these comparisons based on benefits and costs. The report and related materials are available online at http://www.trb.org/Main/Blurbs/173928.aspx
