The quality of the roads drivers travel on every day impacts the amount of fuel vehicles use, as well as the associated greenhouse gas emissions. On roads where surface conditions are poor or structural properties are inadequate, vehicles consume additional fuel beyond what is needed to move. This wasted fuel is known as excess fuel consumption. Improving road design and conditions results in instant environmental and economic payback.
