熊本市中心市街地来訪者分類と総来訪者数の推計に関する研究

摘要

1.Background In the recent city center of Kumamoto, the acceleration on hollowing out of commercial facilities has been concerned by the development of large shopping center in the suburbs and inter-city competition caused by the opening of Kyushu Shinkansen. To cope with this tendency, Kumamoto city has made several town plannings for revitalizing the city center since 2007. The purpose of this study is to estimate the numbers of visitors by their characteristics on round trip route and purchasing behavior, and to find out some factors to vitalize the city center. 2.Study Method Behavioral survey on the city center visitors was made in the year 2008 and 2009. We asked 16 items by the interview on 5 days in 2008, l) Visited stores, 2) Items of purchase, 3) Frequency of visit, 4) Purpose of the visit, 5) Point of the interview, 6) Walking roads and so on. In 2009, 28 surveyors observed traffic volumes of visitors at 279 points of the city center from 9AM to 5PM on two days. We classify city center visitors into the 5groups by the round trip and consumption index. Multiple regression analysis was employed to estimate the numbers of visitors into the city center by using above mentioned survey results. Traffic volume of each observed points is objective value and the numbers of visitors on each round trip rout is independent value. The regression coefficients should be positive number because of the regression model structure. The results of this analysis are shown in the map by using GIS. 3. Conclusion In this research, we classified town visitor into 5groups from the perspective of rambling activities and consumption behavior. We found that characters of visitor's behavior were different group by group. The characteristic of first group can be generalized as low consumption but high visit frequency in this group. In contrast, the fifth group is high consumption but low visit frequency. Not only the person who consume large amount of money, but also the person who stay long time is important, because that makes the town lively. In fourth group, they visited the city for the purpose of large stores. We advocate planning shopping malls with large parking for increasing access to other places in city center. The third group is enjoying the whole city, rambling long distance, long staying time, visit to various stores. For the group that rambling area is small, the furtherance of rambling in side streets is necessary. People using public transport have a tendency to ramble wide area. Total number of estimated city center visitors is 17,900 people on weekday and 30,400 people on holiday. Total consumption of all visitors is about 118 billion yen in downtown area year. We proposed several policies and means for revitalize the city center based on the characteristics of each group.%中心市街地衰退という問題は、近年全国的に広がりをみせている。特に地方都市において深刻であり、熊本巿もそのうちのひとつである。熊本市では近年、九州新幹線鹿児島ルートが全線開通し、福岡市との都市間競争が問題視されている。また、郊外大型店の進出により、中心市街地の空洞化が懸念されている。その様な中、熊本市では平成19年に中心市街地活性化基本計画を策定し、城下町という歴史的な魅力と中心市街地の魅力向上により、来訪者の回遊を促すことから活性化を図るまちづくりに取り組んで来た。
