ABSTRACT
Pavement surface characteristics and the associated pavement vehicle interaction (PVI) affects vehicle operating costs (VOC) and excess fuel consumption (EFC). This paper summarizes an evaluation of six current PVI models that consider pavement roughness and/or texture through a parametric study of the model inputs. The intent of the study was to gain a better understanding of the sensitivity of the different models to the various PVI input parameters, and to further assess the impacts of pavement surface characteristics on EFC. In general, all models indicated that increase in roughness, texture, speed and vehicle weight results in increased fuel consumption. Exceptions are noted along with some unidentifiable contradictions that may be associated with the empirical nature of some of the models.
