Benefit Cost Models to Support PMS Decisions
| 项目名称： | Benefit Cost Models to Support PMS Decisions |
| 摘要： | A goal of the Ohio Department of Transportation (ODOT) is to achieve steady state system condition. The amount of funding required to achieve and to maintain steady state level of service is dependent upon the selection of an optimal mix of treatment categories (new construction, major rehabilitation, minor rehabilitation, and preventive maintenance) and timing. A pavement management process is necessary to assess system condition and determine cost effective strategies. Under previous research projects, researchers have developed, and ODOT has populated, a pavement management information system (PMIS) which consists of pavement design history, rehabilitation actions, costs, and performance in terms of pavement condition and ride quality. Tools in the PMIS provide decision makers with the ability to predict future pavement condition. These tools provide decision makers with the ability to perform "what-if" analysis of both the financial impact and level of service to the public. However, the financial analysis must consider costs of future maintenance and rehabilitation in addition to current spending. Given the size of the pavement network and the number of competing project candidates, the number of feasible alternatives will be very large. Therefore, it is desirable to have a procedure to quickly narrow down the alternatives, and assist ODOT decision makers with choosing among the "near optimal" plans. A research study to develop such a procedure is warranted. The objective of this study is to enhance PMIS by developing and incorporating procedures and routines to (1) investigate and quantify the mid to long term financial impact of selecting alternative projects; (2) define and determine the optimal multi-year work plan according to ODOT specified criteria such as maximizing statewide pavement network condition, subject to budgetary and other constraints; and (3) determine the required multi-year budget, by treatment category, to preserve the existing system at a specific steady-state condition. This research project has the following tasks Task 1: Perform a literature review and conduct a survey to identify benefit cost and budget optimization and allocation models and procedures used by other state and foreign transportation agencies. Task 2: Review ODOT's PMIS to determine the availability of data. Task 3: Summarize and report the results of the literature search and survey. Summarize the pros and cons of each benefit cost and budget optimization model and procedure identified. Identify any deficiencies in the PMIS data for the various procedures. Recommend a procedure for use by ODOT. Task 4: Modify ODOT's PMIS application or develop an application compatible with ODOT's PMIS to perform the analysis/procedures identified in Task 2 and selected by ODOT for use. Task 5: Validate the modified PMIS by using historic distress and cost data to predict current conditions. Task 6: Prepare and submit a final report detailing the work performed for this project. Standard reports as required by the RD&T2 Manual of Procedures; and updated PMIS. |
