摘　　要：为保障高速公路改扩建施工区行车舒适与安全,减少交通事故发证率,考虑驾驶人行车舒适性,针对驾驶人视认和决策行为特征,构建基于驾驶人行为特征的限速模型,提出一种高速公路改扩建施工区限速梯度判定模型,并结合荣乌高速改扩建施工区进行仿真验证。研究结果表明:不同限速类型能够应用在3 km、6 km和9 km高速公路改扩建施工区,同梯度减速区间对应的三级限速行车舒适性大于二级限速与单一限速。To ensure the comfort and safety of driving in the construction area of highway renovation and expansion, reduce the issuance rate of traffic accidents, and consider the driving comfort of drivers, a speed limit model based on driver’s visual recognition and decision-making behavior characteristics is constructed. A speed limit gradient judgment model for the construction area of highway renovation and expansion is proposed, and simulation verification is carried out in combination with the construction area of Rongwu Expressway renovation and expansion. The research results indicate that different types of speed limits can be applied in the construction areas of 3 km, 6 km, and 9 km highways, and the driving comfort of the third level speed limit corresponding to the same gradient deceleration interval is greater than that of the second level speed limit and a single speed limit.
