Abstract:

The Florida Department of Transportation has commissioned the University of Florida to perform a research study to develop user cost models for the Department's implementation of AASHTOWare (trademark) Pontis (trademark). The project features a literature review and survey, a thorough analysis of the sensitivity of Pontis to various user cost factors using Florida bridge data, gathering of additional data available within the Department, and analysis of the additional data. Because Pontis is already installed and operational, the research necessarily has a strong implementation component, working closely with the users of the system to ensure that the results can readily be put into practice. Among the products of the research will be some improved components of the user cost model, and a roadmap for the agency to supplement its existing data resources in the future to continue to improve the effectiveness of the models. At its current stage, the project has developed an updated description of the mathematical form of the models, using a software testing methodology that may prove useful to any agency evaluating the reliability and suitability of new engineering or decision support software. The sensitivity analysis has identified the strengths and weaknesses of the model and established priorities for further investigation in the rest of the study. A request has been made to the Pontis Task Force for certain enhancements to allow Pontis to accept the improved components that Florida would like to develop.
