doi:10.3969/j.issn.1674-0696.2021.12.01

摘要/Abstract

摘要： 为研究安全预警系统对高速公路浓雾区路段控速行为和驾驶安全性的影响，搭建了不同安全预警系统下驾驶模拟环境，通过驾驶模拟实验获取了35位驾驶员的驾驶行为数据。将研究路段分为3部分（无雾区、雾区渐变段和浓雾区域），分析不同实验条件（无预警、动态信息标志预警、车载预警、车载预警&动态信息标志预警）对控速行为和驾驶安全性的影响。研究结果表明：驾驶员的个体属性（性别、年龄和驾驶经验）对驾驶员进入雾区前后的控速行为没有显著性影响，雾区预警系统对驾驶员进入雾区前后的控速行为表现出显著影响；在车载预警条件下，驾驶员进入雾区前控速行为准备更充足，且进入雾区后运行稳定性较好；预警信息可以提高雾区前后的纵向驾驶安全水平，且车载预警系统开启时，纵向驾驶安全水平更高。

Abstract: In order to study the impact of safety early warning system on speed control behaviour and driving safety in dense fog area of expressway, the driving simulation environment under different safety early warning systems was established. Through the driving simulation experiment, the driving behavior data of 35 drivers were obtained. The studied section was divided into three parts (no fog area, fog area transition section and dense fog area), and the influence of different experimental conditions (no warning, road facilities warning, on-board warning, on-board warning & road facilities warning) on speed control behavior and driving safety were analyzed. The results show that: the drivers individual attributes (gender, age and driving experience) have no significant impact on the drivers speed control behavior before and after entering the fog area, while the fog area early warning system has a significant impact on the drivers speed control behavior before and after entering the fog area. Under the condition of on-board early warning, the driver is more prepared for speed control before entering the fog area, and the operation stability is better after entering the fog area. Early warning information can improve the longitudinal driving safety level before and after the fog area, and when the on-board early warning system is turned on, the longitudinal driving safety level is higher.

Key words: traffic engineering; safety early warning; dense fog area; driving simulation; driving behavior
