【摘要】：近几年,高速公路上因右侧硬路肩宽度设置不合理而引起的道路交通事故频发。道路环境不同间接引起的驾驶行为紊乱是导致交通事故发生的重要因素。因此,针对高速公路不同右侧硬路肩宽度对驾驶行为协调性影响问题,从驾驶人视觉感知角度出发,以广东省高速公路实际调研资料为基础,选取右侧硬路肩宽度不同的典型路段,深入分析右侧硬路肩宽度对车辆行驶左右偏移量及车速分布的影响。研究结果表明:当驾驶员行驶于高速公路最外侧车道时,右侧硬路肩宽度的不同对驾驶行为协调性的影响显著,合理的硬路肩宽度易使驾驶员处于安全、舒适、高效的驾驶状态,驾驶行为协调性较好;而过窄或过宽的硬路肩宽度易引起驾驶员紧张和分心,间接造成驾驶行为紊乱,增加发生交通事故的可能性。
[Abstract]:In recent years, there are frequent traffic accidents caused by the unreasonable setting of the right hard shoulder width on the expressway.The disturbance of driving behavior caused by different road environment is an important factor leading to traffic accidents.Therefore, in view of the influence of different right-side hard shoulder width on the coordination of driving behavior, from the perspective of the driver's visual perception, based on the actual investigation data of Guangdong expressway,In this paper, the influence of the width of the right hard shoulder on the movement of the vehicle and the distribution of the vehicle speed is analyzed in depth by selecting the typical road sections with different width of the right hard shoulder.The results show that when the driver is driving in the outermost lane of the expressway, the difference of the width of the right hard shoulder has a significant effect on the coordination of driving behavior, and the reasonable width of the hard shoulder makes the driver safe and comfortable.The driving behavior coordination is good in efficient driving condition, while the narrow or too wide hard shoulder width can easily cause driver tension and distraction, which indirectly cause driving behavior disorder and increase the possibility of traffic accident.
