The expressway of the Korea has an important role in freight movement because 76 percent of the commodity is transported by trucks. However, there has been few indices on the role of expressways regarding freight transportation and truck traffic. The objective of this study is to propose four freight transportation related indices using ITS-related system such as TCS and HS-Wim: total truck’s travel miles (veh . km/year), total freight transport miles (ton . km/year). efficiency of truck’s travel (veh . km/km), and efficiency of freight movement (ton . km/km). These truck and freight related indices were estimated and compared by two different data sources: traffic volume data using VDS and OD data using TCS. These indices were designed to estimated on real time and updated every day and month. keywords: efficiency of freight movement, efficiency of truck’s travel, freight transport miles, smart restrictive vehicle analysis system, truck’s travel miles
