交通動線規劃常以車輛為導向，而較忽略行人考量。當駕駛人於駕駛上有所疏失或不當行為時，便會導致車輛衝撞行人的事件。本研究目的是探討藉由警示回饋信號協助行人與駕駛者雙方避免危險。首先以問卷探究道路環境對受訪者心理層面上的影響；及不同時段的差異性。歸納問卷結果，行人認為計時功能與聲音提示可減輕心理壓力；以時間方面而言，夜晚與尖峰時段，受測者很明顯的感到緊張。其次以實驗測試受測者對於行人穿越設施中聲光兩類警示號誌之感受度，選取不同聲音樣本與燈光閃爍頻率並以單因子變異數分析做差異性檢驗。聲音樣本波包頻率高，具有強警示特質，燈光閃爍週期與危險感覺強度成負相關。適當的警示回饋將可提高人行道的安全性。

Traffic line often ignored the pedestrian considerations. The behaviors and need of pedestrian in different situations were studied by questionnaire and observation. Anxiety during crossing in traffic peak time and nighttime is higher than normal. The sound warning and timer during crossing are helpful to reduce anxious. Two set of experiments were conducted to find how to caution walkers and drivers to enhance security. The sound and light effect were studied by experimental approaches to find out suitable parameters. The high frequency wavelet has higher wariness. The flashing period is inversely proportion to people's wariness. By using suitable warning feedback can help pedestrians to avoid possible accident caused by the high-speed vehicle.
