Utilization of Big Data Analysis to Build up Pavement Life Cycle Assessment in Taiwan Freeway

Growing number of road in Taiwan was followed by the increasing number of agencies, companies,organizations, institutes, and governing. Budget limitation, environmental condition and increasing ofthe transportation volume become issues and must be analyzed. It becomes essential to embracingsustainability for their business activities as an effective tool to assist in the selection of construction,rehabilitation, and maintenance treatments for the roads. As an important feature of sustainability, lifecycle assessment emphasizing economic, environmental, and social factors in the decision-makingwith more systematic and organized. Life Cycle Cost Analysis (LCCA) and Life Cycle Assessment(LCA) can be used to quantify the budget and environmental performance with sustainabilityconsiderations. FHWA report FHWA-SA-98-079 developed LCCA as incorporates initial anddiscounted future agency, user, maintenance, and other relevant costs over the pavement life as analternative investment. It attempts to identify the best value as the lowest long-term cost that satisfiesthe performance objective for investment expenditures. LCA incorporates environmental impacts overthe full life cycle of a product or system, including impacts that occur throughout the production,maintenance, and use phase of pavement. The big freeway database is needed for analyze thepavement life cycle that takes the main role for the efficiency, sufficiency and reliability funding, alsofor the environmental and responsible for substantial energy and resource consumption. This projectwill predict pavement life cycle and long term road network performance as a function of trafficvolumes and loading, road pavement type, pavement condition, and maintenance standards; optimizethe overall performance over the time, in accordance with policy objectives and within budgetaryconstraints; and analyze the environmental effect for whole pavement life cycle in case of Guanxisection as part of Taiwan National Freeway no.3. HDM-4 use to simulate total life cycle conditionsand costs for an analysis period with comparative cost estimates and economic analyses of differentinvestment options. Based on the combination of FHWA software, local parameter, big data analysisand life cycle assessment in study, the results of this this should be worthy to further study andreference.
