目前對於市中心商圈行人遊逛實態的了解似乎仍不夠充分，特別是行人在遊逛過程中，「集客據點間的距離與配置型態」與「主軸線、次軸線與建築物通道之利用效果」等，涉及都市設施配置與行人遊逛之關係仍有待釐清。本研究以高雄市新堀江商圈爲研究場域，利用隨機抽樣設計追蹤594組行人（共1330人），而後利用追蹤調查所獲得之步行路徑資料，來確立行人遊逛的基本尺度單位，再透過遊逛範圍的模式化與類型化，來呈現商圈空間結構之實態。研究結果發現，市中心商圈內欲形成各種形式之遊逛單位時，核圈域的存在與否是關鍵要因，因此核圈域的整建相對於路網整建（含主軸線、次軸線與建築物通道）更爲重要。此外若缺乏次軸線，則即使有遊逛人次比率較高的主軸線亦不能產生遊逛單位。

It seems that pedestrian excursion behavior is not well recognized in downtown business districts. "Distance and allocation between attractors" and "effects of major axis, secondary axis, and building passage", which related to the problems of relationship between facilities allocation and pedestrian excursion are extraordinarily unclear. This study adopted follow-up-pedestrian survey to collect data, Commeraial Zone of Kaohsiung City as a research field, and the pedestrian trip collected from 594 group samples, total 1330 pedestrians, were used to decide "basic scale unit". Furthermore, excursion areas are modeled and classified to display pedestrians' excursion situation and structure of street space, and construction strategy at empirical area could be provided. This study found that the major component to form a excursion unit is the existence of a core area. Consequently, constructions to core areas are more important than that to street networks, which include major axis, secondary axis and building passage. This study also found that major axis with high pedestrian rate can not certainly form a excursion unit without secondary axis.
