| 摘要： | Research Project 0-4186 entitled, 'Cradle-to-Grave Monitoring of Pavements and Pavement Management Information System (PMIS) Functionality Enhancement Planning,' is intended to develop strategic plans for integrating the pavement-related databases at the Texas Department of Transportation (TxDOT) and enhancing the decision support functions in the PMIS. To integrate pavement-related data, a new information system is proposed. This report presents a comprehensive cost-effectiveness analysis as a part of the feasibility study for developing the proposed information system. The concept of information system integration is outlined first, followed by a brief review of the current pavement-related databases and a discussion of the conceptual framework for the proposed information system. Then, potential methods for conducting cost-benefit analysis are reviewed. Using the findings from the review, a framework for cost-effectiveness analysis is established with an eight-step process. Using the eight-step process, the cost-effectiveness analysis for the proposed information system is conducted. Sensitivity analyses are also performed to examine the relative impact of the selected input parameters on the output of the cost-effectiveness analysis. Based on the analysis results from the capital budgeting models, it is evident that the investment on developing a new information system to support the pavement engineering and management activities at TxDOT is fully justified. |
