- Abstract:
- The American Association of State Highway and Transportation Officials (AASHTO) and Federal Highway Administration (FHWA) encourage the use of various Accelerated Bridge Construction (ABC) strategies, which can help reduce onsite construction time, minimize traffic and environmental impacts, improve work zone safety, and deliver longer lasting and more durable bridges. ABC approaches include the application of technical innovations and management techniques. The decision to use ABC must be made on a project-by-project basis as each bridge location is unique, and factors constraining each project are different. Toward this end, FHWA developed a qualitative decision making framework called Analytic Hierarchy Process (AHP) to determine whether prefabricated bridge elements should be considered for a given project. The simplest AHP form consists of three levels, the overall goal of the decision, the criteria by which alternatives will be evaluated, and the available alternatives. A hierarchical structure of decision criteria helps the user decompose the decision into comparisons between each set of criteria
