Abstract: The annual vehicle kilometers traveled (AVKT) is essential to study the transportation and environmental protection. The key influencing factors of AVKT include vehicle type, regional transportation capacity, and vehicles’ technique conditions. Because it is difficult to obtain the exact value of AVKT under current technical conditions, AVKT has to be estimated according to other data. Based on the analysis of the influencing factors of AVKT, this study develops an algorithm to calculate AVKT on the basis of a small sample. The establishment of calculation formula is based on the data of vehicle type, vehicle licensing, accumulated mileage, and vehicle population. This study also proposes an algorithm to calculate vehicle mileage distribution based on the accumulated mileage. The research shows that AVKT is determined by the vehicle type distribution, vehicle age distribution, vehicle mileage distribution, and the accumulated mileage. With consideration of various factors, the method is suitable for a variety of classification standards and can be generalized to some extent. The method is also exemplified by the data and is proved to be feasible.
