以往行人設施服務水準評估方式乃採用車流服務水準想法而來,透過密度、流量及速率方法評估行人通道優劣。但行人行走較車輛運行擁有較高自由度,且在通道中行進方向並非為單一方向。因此,該方法雖可評估通道擁擠程度,但無法評估行人受干擾程度。因此,本研究以建立行人干擾指標研究目標,提供日後研究者評估使用。本研究透過行人受干擾兩反應分別建立兩行人干擾評估方式偏 移率及干擾熵,其中偏移率乃用以衡量行人在通道中受干擾所產生偏移的程度;干擾熵衡量行人在通道中受干擾速率的變化程度。研究中實地拍攝捷運台北車站行人流動狀況以分析不同行人參數對干擾程度的影響,發現區域密度以及動線方向比對行人干擾程度皆有正向關係、干擾與速度之間有反向關係;此外,偏移率及干擾熵兩指標之間有一正向線性關係。研究中並針對不同乘客以影片問卷方式調查干擾程度認知,再透過模糊理論區分六個干擾等級,以做為判定通道行人流動干擾程度評估標準,最後並透過實例應用說明本研究所建立干擾指標有其實用性。
The transitional pedestrian flow evaluate method is like the traffic flow by the density,flow and speed, but the method could not evaluate the pedestrian conflict. Because pedestrians have moved more freedom then car. So this study wants to establish a new method to provide the planner and manager to evaluate the pedestrian facility. According to the observation, this study builds on two conflict indexes, the first one is conflict entropy which to calculate the pedestrian variance of walking speed, another one is dodge ratio which to evaluate the degree of pedestrian departure when pedestrian run into conflict. The result shows the conflict and density, direction ratio has positive liner relation, the speed has the negative relation, and the conflict entropy and dodge ratio have the positive liner relation. Besides, in order to provide more effective indexes to the planners and managers, this study has also divided six conflict index scales by fuzzy theory.
