基于Uchida-Kraepelin心理测试的酒后驾车交通事故倾向测量

针对利用驾驶员的血液酒精浓度一致标准测定和问责酒后驾车行为的方案在某些场合可能不够严谨的问题,为探索新型测量技术,招募18位驾驶员开展酒后Uchida-Kraepelin心理测试(UK测试).结果显示,随着驾驶员饮酒量的增加,UK作业曲线从未饮酒时的定型曲线特征逐渐向非定型曲线特征转变,且作业错误率均值递增.定义UK作业偏离度,探明其与交通事故倾向具有一致性,且两者具有正相关性,平均相关系数为0.71.UK作业偏离度能够揭示酒后驾车交通事故倾向,或可作为酒后驾车行为测定和问责的一种新证据参数;基于UK测试分析的酒后驾车交通事故倾向测量是一种可探索方案.

Traffic Accident Tendency Measurement Method for Drunk Driving Based on Uchida Kraepelin Psychological Test

Abstract： In view of the problem that it might not be reasonable enough to evaluate and punish drunk driving according to the blood alcohol concentration of the driver, 18 drivers were recruited to join the Uchida Kraepelin (UK) test in order to discover a novel method. The results showed that work curves of UK changed significantly from shaped style to unshaped style as the drivers drank successively, together with increasing values of average work mistake rates. These helped to define a work deviation value. Experiments proved that there existed monotonic consistency relationships between work deviation values and traffic accident tendencies, together with an average coefficient of 0.71. Thus, UK work deviation value was able to uncover traffic accident tendencies of drunk driving, and probably could be a new evidence for judging and publishing drunk driving. UK test and its results analysis may be a potential method for measuring traffic accident tendencies of drunk driving.
