路燈光源與道路環境對辨識路旁行人反應之影響
Impact of Street Light and Road Environment on the Detection of Roadside Pedestrian
摘要
本研究旨在探討白天和夜晚對於駕駛者在辨識路旁行人過程中，路燈類型和道路環境對其反應時間與正確率之影響。本實驗分為兩部分進行，第一部分針對白天，為一2（陰影：有陰影vs.無陰影）×2（道路環境：住宅區vs.空曠區）之因子實驗設計；第二部分則針對夜晚，採用一3（路燈類型：白光vs.黃光vs.無燈光）×2（道路環境：住宅區vs.空曠區）之實驗設計。收集駕駛者之反應時間和反應正確率進行分析。實驗結果發現，整體而言，複雜的道路環境（住宅區）會使駕駛者反應時間變慢並降低其反應正確率。此外，駕駛者在辨識路旁行人的任務當中，白天反應時間較快於夜晚；在夜晚的行車環境下，黃色光之路燈比白色光或是無路燈之照明環境更容易辨識出路旁行人。

This study aims to investigate the effects of the street light type and the road environment on driver's response of road side pedestrian detection in either daytime or nighttime. In the daytime, a 2 (with or without shadow) x 2 (road environment, residential area vs. open area) experiment was conducted; while for the nighttime experiment, the three street light types (white vs. yellow vs. no-light) and the mentioned above two road environments were designed as the independent variables. The participants' reaction times and response accuracy were collected as the dependent variables. Results show that the driver reacted faster in the daytime than that in the nighttime. Furthermore, in the nighttime with yellow street lights caused drivers to respond the roadside pedestrian faster than them in the white street lights. In general, complex road environment (the residential area) has negative impact on driver's detection and response performance.
