通过对高速公路客观安全性影响因素(道路线形、交通设施、路面状态及自然环境)及主观安全性影响因素(驾驶员的生理负荷——心率、眼动和脑力负荷NASA-TLX)与道路安全的关系进行研究,提出了基于主客观安全性的高速公路综合运营风险评价方法。应用结果表明,该评价体系符合客观实际,为高速公路运行环境安全性评价以及运营安全管理决策提供了理论依据。
By analyzing the influence factors of highway objective security (road alignment, traffic facilities, road conditions and natural environment) and subjective safety factors (physiological load of driver - heart rate, eye movement and brain load NASA-TLX) and road safety The author puts forward the risk assessment method of expressway comprehensive operation based on subjective and objective security. The application results show that the evaluation system is in line with the objective reality and provides a theoretical basis for the safety evaluation of the operation environment of the expressway and the operational safety management decision.
