In general, Shopping centers are located in the center of transportation, which induce more traffic concentration than other facilities. As a result, it becomes to one of the aggravating factors of urban & transportation problem such as traffic conjestion, parking problems.Thus, in planning shopping-center, it is desirable that consumer’s trip pattern is should be more carefully analyzed in order to alleviate the above problems.
This study is aimed at finding the characteristics of shopping trips and analyzing the choice behavior of shopping center and mode-to-shop.
This study has developed a nested logit model in which consumers choose shopping center and mode-to-shop with a sequential structure.
The model was estimated using household data from the 1989 May, Seoul metropolitan area and the 18 alternatives of shopping center and 5 mode alternatives.
The estimated model have been evaluated and it may be concluded that this model for shopping trips is effective and fesible.
The conclusion of this study are as follows.
1. Out-of-vehicle travel time is more important factor affecting behavior of mode choice than in-vehicle travel time.
2. All of direct-elastcities for mode with respect to the travel time is more elastic than travel cost.
3. Accessibility to shop is more important factor affecting the choice of shopping center than parking space.
4. The value of out-of-vehicle travel time exceeds the value of in-vehicle trvel time by 1.64 times.
