基于SCANeR的城市道路应激场景驾驶模拟实验

Stress Scenario Simulation of City Road Based on SCANeR

相较于实车实验,驾驶模拟实验具有更安全、影响因素更可控、实验可重复性高等优势,并更容易获取大量的实验数据。因此利用SCANe R软件对城市道路应激场景进行建模并实现模拟驾驶,对驾驶员反应时间和应激驾驶行为进行实验探究。通过驾驶经验的不同,性别的不同以及行驶速度的不同,将驾驶员分类进行实验。实验结果表明,经验丰富的驾驶员在实际驾车过程中遇到的应激场景较多,对危险信号的出现形式有一定的积累,会在可能出现突发情况的时候给自己一个心理暗示,从而在一定程度上使得感知危险信息的速度较快;女驾驶员的反应时间的波动比较小;在行人横穿马路的情况下,车速对驾驶员的反应影响显著,随着车速的提高,反应时间明显增加。

Compared with the real vehicle many advantages. For example, the driving experiments on the road and the test simulator is more secure and easier drive, the driving simulator has to control, low cost of driving environment, and easy to collect many parameters. Therefore, SCANeR is used to model the city road stress scene and simulates the driving, and to detect drivers＇ reaction time and stress driving behavior. By driving experience of different gender and driving speed of different, the driver classification experiment. The experimental results show that the gender of the driver stress reaction time and operation behavior of stress had little effect on the; experience for this influence are great and speed. It is for individual scene driver response characteristics of the impact is relatively large.
