摘要
为探究城市道路条件下常见驾驶分心行为对驾驶绩效的影响,以 16 名青年志愿者为被试,开展实车驾驶试验,测量车辆纵向和横向行驶参数,对比分析正常驾驶和分心驾驶状态下的驾驶绩效,并探讨驾驶经验的影响.结果表明:3 种分心行为均使横向加速度标准差和纵向加速度标准差增加,而使速度均值降低,说明驾驶员通过速度和转向控制补偿分心状态下的驾驶绩效;交谈对速度均值和纵向加速度均值、阅读广告对速度标准差和横向加速度均值具有显著性影响(p＜0.05);接听电话时,经验驾驶员速度标准差明显高于新手(p=0.021);接听电话和阅读广告次任务下,经验驾驶员的横向加速度均值均明显较高(p=0.003,p=0.004),说明经验丰富的驾驶员受分心行为的影响程度更低.
Abstract
To investigate influences of common distracted driving behaviors on driving performance in the urban environment,three secondary tasks were designed.Sixteen young subjects were recruited.The driving tests were conducted under real conditions.Vehicle longitudinal and lateral driving parameters were measured.The driving performances under normal driving and distracted driving conditions were compared and analyzed,and the influences of driving age on these performances were also discussed.The results show that compared to the normal driving,in all 3 distracted conditions,the standard deviation of longitudinal acceleration and the standard deviation of lateral acceleration increase while vehicle speed decreases.This indicates that drivers compensate for driving performance by speed and maneuver while distracted.The mean speed and the mean longitudinal acceleration are significantly influenced by the talking task,while the standard deviation of speed and the mean lateral acceleration are significantly influenced by reading the advertisement(p＜0.05).The standard deviation of speed is significantly higher for experienced drivers compared to novices in the phoning condition(p=0.021).During phoning and advertisement reading tasks,the mean lateral acceleration is significantly higher for experienced drivers compared to novices(p = 0.003,p = 0.004).This means the experienced drivers are less affected by distracting behaviors.
