The final objective of this research is to estimate the demand for clean-fuel vehicles. This paper first describes the travel characteristics of existing vehicles such as distribution of distance travelled in a day, longest stopping time by vehicle type and region using data from the Road Traffic Census Survey. These characteristics are then compared with the performance level of present clean-fuel vehicles. the major findings are: a) travel characteristics vary much among vehicle types, notably between commercial vehicles and others; b) large portion of smaller cars and mini-cars are operated within the current performance level of corresponding clean-fuel vehicles.
