Pavement vehicle interaction (PVI) is a concept that looks at the interaction between a vehicle’s tires and the roadway surface on which it is driving. It is also known as rolling resistance. Three factors relating to a road’s surface condition and structural properties contribute significantly to PVI: roughness, which refers to how bumpy or smooth a road is; texture, the abrasiveness of the road surface; and deflection, the bending of a pavement under the weight of a vehicle. Traffic patterns and temperature are influential factors as well.
PVI leads to excess fuel consumption (EFC), which is wasted fuel consumption beyond what is required to move a vehicle. EFC contributes to smog and greenhouse gas emissions, and impacts drivers, states, and municipalities financially.
CSHub research has led to models that quantify excess fuel consumption due to PVI for pavement segments and pavement networks.
