在沙漠等特殊环境下,驾驶员的反应特性水平是衡量驾驶员驾驶适宜性的重要指标。为了探索汽车驾驶员的反应特性在特殊环境中的表现特征,本文利用复杂(选择)反应检测仪对沙漠公路行车途中汽车驾驶员进行了实地测试,测试包括反应时间和误反应次数在内的反应特性,并根据获得的有效样本检测数据进行统计整理,对受测驾驶员反应能力总体情况及与驾驶员年龄、驾龄、持续行车时间、检测时的气温等因素之间的关系进行了重点分析。研究表明,受急躁心理影响,沙漠环境下的驾驶员反应速度明显高于平均水平,而误反应次数增多,沙漠公路受测驾驶员复杂反应时间和误反应次数平均值分别为0.74 s和2.91次。关联度分析表明,沙漠公路驾驶员的年龄、驾龄、驾车时间及测试温度等因素与反应时间和错误次数均具有较强的相关性。相对于其他几项因素,驾车时间对驾驶员反应特性的影响最为明显。
In the desert and other special circumstances, the driver’s level of response characteristics is an important indicator to measure the driver’s suitability. In order to explore the characteristics of driver’s response characteristics in special environment, this paper uses a complex (selective) reaction detector to test the driver on the desert highway while testing the reaction including reaction time and number of false reaction Characteristics, and based on the obtained effective sample test data for statistical finishing, the analysis of the overall situation of the tested driver’s reaction ability and the relationship between the driver’s age, driving experience, driving duration, temperature during testing and other factors were analyzed. The research shows that under the influence of impatience, the reaction speed of driver in desert environment is obviously higher than the average level, while the number of false reaction increases. The average reaction time and number of false reaction of pilots in desert highway are 0.74 s and 2.91 . Correlation analysis shows that the drivers of desert highway age, driving experience, driving time and test temperature and other factors and the reaction time and the number of errors have a strong correlation. Driving time has the most pronounced effect on driver response compared to several other factors.
