應用計畫行為理論探討行人對互動式交通號誌之使用意圖

Modeling Pedestrian Behavioral Intention toward Interactive Traffic Signals using the Theory of Planned Behavior

行人因等待時間過長或分心使用手機而闖越馬路，導致城市交通事故頻傳。為此，本研究引進並改良德國的創新概念，提出互動式交通號誌系統。我們運用計畫行為理論（TPB）作為分析框架，旨在探討行人對此系統的行為意圖及其影響因素。以台北車站行人為對象，透過問卷調查法蒐集數據，共獲得396份有效樣本。實證結果顯示，行人對互動式號誌的態度、主觀規範以及知覺行為控制三項構念，均與其使用意圖呈顯著的正向關係。本研究建議交通管理單位可採用此策略，藉由設計互動機制，有效降低行人因分心造成的交通意外風險，同時增進公共空間的良性互動，為智智慧交通規劃提供重要參考。

Urban traffic accidents frequently arise from pedestrians jaywalking due to long waiting times or being distracted by mobile phones. To address this critical safety and efficiency conflict, this study introduces an optimized concept of interactive traffic signals, adapted from a German design. We utilize the Theory of Planned Behavior (TPB) as the analytical framework to investigate the key factors driving pedestrians' behavioral intention toward this novel system. Data was collected via a questionnaire survey targeting pedestrians at Taipei Main Station, yielding 396 valid responses. The empirical results confirm that pedestrians' Attitude, Subjective Norms, and Perceived Behavioral Control (PBC) all demonstrate a significant positive relationship with their intention to use the interactive signals. We suggest that traffic authorities consider this strategy to effectively mitigate accident risks caused by distraction and foster positive social interaction in public spaces, offering valuable guidance for smart city planning.
