摘要：	Life-cycle cost analysis (LCCA) uses economic principles to compare competing investment alternatives. It is used by the Alabama Department of Transportation (ALDOT) to help select between asphalt and concrete alternatives for large paving projects. The purpose of this University Transportation Center for Alabama research project was to collect data that will assist ALDOT in determining the user costs or vehicle queue lengths that may result from a highway work zone. This project was the second phase of a multi-phase project to update the LCCA process. The researchers investigated the following areas: Project/Work zone duration data for typical Interstate reconstruction and rehabilitation activities. Investigation of typical work zone configurations (i.e. lane closure scenarios) for Interstate rehabilitation activities. Investigation of two software packages capable of calculating vehicle queue lengths. Evaluating the effectiveness of calculating user costs with FHWA's RealCost v.2.1 software. Appropriate recommendations were made to ALDOT to reflect the findings of the research.
