The Transportation Service Index (TSI) is a monthly (quarterly) measure of the volume of services performed by the for-hire transportation sectors. The objective of this study is to develop and analyze TSI for cross-border transportation. The cross-border transport is classified into four sectors: air passenger, maritime passenger, air freight and maritime freight. For each sector, a seasonal adjustment model is developed. Passenger index and freight index are calculated by employing the Fisher's ideal index method. The Cross-border Air Passenger and Freight TSIs steadily increased from 1995 to 2008. These can be lagged index comparing with the business cycle in Korea. The cross-border TSIs are not likely to be useful in forecasting economic activity in the future. However, they can be useful for transportation planning and decision-making: monitoring of transportation service changes, analyzing the effect of the execution of transportation policy and so on.
