Comparing Ranking and Optimization Procedures for the Texas Pavement ManagementInformation Systems

摘要

The Pavement Management Information System currently implemented within TxDOTcontains a simple single year ranking procedure for prioritization of projects and for conducting impact analysis. The report compares the performance of this ranking procedure with two multi-year optimization procedures, one that only permits a single treatment during the planning period, the other allows multiple treatments. A case study of 23 sections is used to compare the three methodologies and their effectiveness is compared in terms of how the individual sections are prioritized and the overall pavement condition at the end of the planning horizon.
