Shingal - Ansan Freeway, opened to traffic in November 1991, is playing a role of one of the national industrial arterials by carring mainly the industrial freights of Seoul - Incheon Region. The proportion of truck traffic in the total traffic volume of the route reached at 40%. However, transportation demand far exceeds the capacity of the freeway, resulting in a serious traffic congestion and weakened national competitiveness. This study is carried out to seek for short - term traffic improvement measures which can be implemented in advance of the planned widening project. Specifically, causes of traffic congestion are studied and the effectiveness of each improvement measure was analyzed.
