Abstract:

Accurately measuring freight traffic volume and traffic volume structure of the road network plays an important role of supporting the decision- making of the competent departments in transportation industry. This study proposes an improved statistical method for regional network freight traffic volume measurement using truck daily average section traffic volume and equivalent mileage as two analogy indexes. The proposed method considers the relationship between regional network transport volume and vehicle transport volumes and analyzes the full sample data from expressway toll collection and highway traffic surveys. The traffic volume of regional road network was refined based on the highway technology level. The structural transport volume was then obtained, and the connection between regional network transport volume and vehicle transport volume was established. The case study analyzed the freight transportation in Yunnan province of China. The results indicate that: the freight turnover of high-grade highways accounts for about 71% of total regional turnover volume. The freight turnover of Expressway accounts for 54% . The freight transport volumes between Yunnan and other provinces are relatively low, which indicates the degree of economic openness needs improvements.
