영어 초록

Since 1960's there have been conducted quite numbers of origin and destination (O-D) surveys in Korea. Most of them, however, were to be said not so successful.
In this paper, it was investigated that why the previous O-D surveys were failed, and that how it could be improved. The findings of this study are:
1. The collection of sample data itself was performed relatively well, but the problem was in the improper expansion methods which were applied.
2. To improve the expansion methods, it should be performed not only the dwelling unit-based sample surveys but also commercial vehicle survey, cordon line survey, screen line counts and other auxiliary travel surveys like transit patronage survey, vehicle miles survey etc. at the same time.
3. To expand the sample surveyed data in a proper way, the adjustment factors should take a disaggregate form and also should be applied not to the specific trips, but to the specific trip makers to avoid the bias which could be caused by the application of adjustment factors in a way that has been used previously.
4. If there is no considerable change in travel patterns, we can synthesize the present O-D data with past surveyed sample data, using present statistic data in the same way which was developed in this paper when expanding and adjusting sample data.
