驾驶任务缓急与汽车驾驶倾向性的相关性

Correlation between task urgency and driver's propensity

以驾驶任务缓急程度为研究对象,对50名被测试者分别进行3次不同缓急程度运输任务的实验研究,获取在不同任务缓急程度下驾驶员的各项生理和心理特征数据,计算相应的汽车驾驶倾向性预判值.运用单因素方差分析方法,分析任务缓急程度与驾驶倾向性的相关性.研究结果显示,在较缓、一般缓急和较急3种任务缓急程度的情况下,驾驶倾向性影响因子(驾驶员的速度估计偏差、操作反应时间、注意力和情绪等)的值显著不同,表明任务的缓急对驾驶倾向性影响显著.

The transportation task urgency was taken as the study object. Transport task experiments of three different degrees of urgency were organized for 50 drivers. The physiological and psychological feature data of drivers were obtained. And the pre-judgment values of driver＇s propensity and driver＇s propensity was elaborated through one-way analysis were calculated. Correlation between task urgency of variance. Results show that the values of the impact factors of driver＇s propensity are significantly different in the cases in three task priorities of the slowness, the general urgency, and the most urgency. The characterization parameters considered are the driver＇s speed estimation bias, the operation response time, the attention, the emotion and so on. Namely task urgency has significant effect on driver＇s propensity.
