摘要

路口是行人最容易發生危險事故的地方，本研究探討行人穿越路口的安全問題與對應的設計建議。研究共分為三調查，第一個調查為觀察實驗，探討行人在常見五種類型路口的違規穿越行為。第二個調查為問卷，探討行人穿越路口的安全意識。第三個調查以台北市和平東路圓環為範例，透過非參與式觀察法理解高風險圓環中行人穿越的行為與策略。研究結果顯示，儘管號誌秒數是根據Webster公式訂定，但路口秒數是行人做出穿越決策的重要依據。根據和平東路圓環調查發現：基隆路口提前秒數高達10秒，會誘發行人提早穿越。基隆路口也由於綠燈秒數僅有30秒，使得行人無法在時間內順利通過。和平東路口由於隱藏秒數高達26秒，增加了行人紅燈後滯留路口的行為。調查可知公式無法適應所有類型的路口。因此，號誌秒數的設計應配合實際的環境作出調整，而行人也應提升法規號誌的安全意識，以維護自身穿越路口之安全。

The most dangerous accident-prone place for pedestrians is the intersection. This research explores the safety problems of pedestrians crossing intersections and gives related design suggestions. The research is divided into three parts. The first is observation experiment, which explores the illegal crossing behavior of pedestrians in the five most common intersections. The second is questionnaire survey, which explores the pedestrian’s safety conscience when crossing intersections. The third is to investigate through nonparticipant observation to understand the pedestrian's crossing behavior and strategy in high risk roundabouts.
The research shows that, despite the signal’s seconds are set by the Webster Formula, the seconds available for pedestrians to cross the intersection is the most important factor. According to the Heping E. Road’s roundabout survey, the signal on Keelung Road intersection has a ten-second gap between the signal turning green and the cars stopping, which induces pedestrians to cross the intersection in advance. Keelung Road’s green light signal is only available for thirty seconds, which makes it impossible for pedestrians to cross in time. Heping E. Road’s intersection has twenty-six seconds between the signal’s red light and the cars moving, which increases the behavior of pedestrians staying at the intersection. From the observation, the formula isn’t suitable for all kinds of intersections. Therefore, the design of the signal’s seconds should be adjusted according to the actual environment. Pedestrians should also better acknowledge the traffic signals to ensure their own safety.
