摘　　要：长大下坡是公路高风险路段,主动交通安全防控是该路段的重心工作。然而如何合理确定交通状态感知设备覆盖率,以及如何制定防控方案仍缺乏论证。本研究首先基于互联网出行数据分析长大下坡特殊风险路段交通运行风险特征,通过数据驱动方式对长大下坡路段交通风险进行评价;随后基于评价结果制定不同等级的交通状态感知设备布设方案和交通风险防控方案;最后开展驾驶模拟实验探究高速公路长大下坡路段交通风险防控方案对驾驶行为的影响。本研究考虑速度调节水平、操作稳定水平、心理舒适水平及风险意识水平4个维度构建多维综合评价指标体系,以分析交通状态感知设备不同覆盖率对驾驶行为的影响效应。In recent years,active traffic safety prevention and control has become the focus of safety improvement on long downhill sections of highways.However,how to reasonably determine the coverage rate of traffic state sensing equipment and how to formulate prevention and control plans are still lacking.This study first analyzes the traffic operation risk characteristics of long downhill special risk sections based on Internet travel data,and evaluates the traffic risks of long downhill sections in a data-driven way;then,based on the evaluation results,different levels of traffic state sensing equipment deployment plans and traffic risk prevention and control plans are formulated;finally,a driving simulation experiment is carried out to explore the impact of traffic risk prevention and control plans on long downhill sections of highways on driving behavior.This study considers the four dimensions of speed regulation level,operational stability level,psychological comfort level and risk awareness level to construct a multidimensional comprehensive evaluation index system to analyze the impact of different coverage rates of traffic state sensing equipment on driving behavior.
