驾驶员危险知觉测试及其信效度分析
首发时间:2015-09-08
摘要:为了开发以动态交通视频为基础的驾驶员危险知觉测试,将反应时方法和眼动方法相结合,利用Tobbi眼动仪呈现75个从驾驶员的视角拍摄的动态交通视频(50个视频包含危险)对152名驾驶员进行试验。结果表明:删除不能有效地区分不同驾驶经验驾驶员的视频,最终保留26个视频组成危险知觉测试。测试的内部一致性信度为0.903,对不同驾驶经验驾驶员的整体分类准确性为82.7%。眼动数据分析进一步验证了测试的有效性,驾驶员对危险兴趣区的注视次数越多,总注视时间越长,他们对潜在危险的反应时间越短。总体来说,驾驶员危险知觉测试的信效度较好,适合用于我国驾驶员行为评估、驾驶训练和驾照考试等方面。

Driver's Hazard Perception Test and Its Reliability and Validity
Abstract:In order to develop a hazard perception test for Chinese driver by using dynamic traffic video, we tested 152 drivers by combining reaction time method and eye movements method. 75 dynamic traffic videos shooting from the drivers' view, among which 50 videos contained a latent hazard, were showed by Tobbi eye tracker. Results showed that after eliminating those problematic videos and those videos that can't distinguish novice and experienced driver, a 26-video HPT was finally got. The reliability of the HPT (Cronbach's α) was 0.903. The overall classification accuracy of the HPT was 82.7%. Further analysis of eye movements data verified the validity of the HPT. We found that the more drivers' fixations and the longer their total fixation time, the faster they can react to the latent hazard. Therefore, the reliability and validity of the HPT was well and it suited for assessing Chinese drivers' hazard perception ability.
