DNE21+ represents road transportation sector in two way. One is vehicle type and the other is technological category. The type of vehicle includes small passenger car, large passenger car, bus, small truck, and large truck. Vehicle technologies are categorized into internal combustion engines, electric cars, fuel-cell cars, and alternative fuel vehicles, including bioethanol mixed with gasoline, biodiesel mixed with diesel, and CNG. The gasoline and diesel combustion engines for gasoline/diesel are further classified into conventional internal combustion cars (low/high efficiency), hybrid cars, and plug-in hybrid cars.

Scenarios on service demand of road transportations are developed for passenger cars and buses separately based on per-capita GDP and the historical trends. As for road freight transport (t-km) scenarios of cargo trucks, overall cargo service per-capita is estimated by the GDP size, and then the transition of modal share is assumed.
