Abstract:The objective of this study was to evaluate the accuracy of the FHWA LCCA user delay cost model in estimating user delay costs for roadwork projects in Louisiana. This research addressed only the user delay cost component of the FHWA LCCA model. Evaluation of the FHWA LCCA model was limited to two state roadwork projects in progress at the time of this study, I-10 in LaPlace and I-10 in Lake Charles. The evaluation consisted of 1) analysis of the accuracy of model inputs, 2) analysis of the model outputs as compared to actual delay times observed, and 3) sensitivity analysis of the model’s user delay cost estimates to errors in model inputs.
