39636 本系统有效解决了传统培训中存在的枯燥乏味、实践机会少、易发生危害等问题，为其他领域相关系统的开发提供了参考。 The system effectively solves the problems of boringness, less practical opportunities and damages in traditional training, and provides reference for the development of related systems in other fields.
39637 为了研究道路交通系统中“人-车-路”多因素对驾驶行为及车辆安全状态的影响，设计了多因素组合成6种场景的模拟驾驶对照试验。 In order to study the influence of multi-factors of human-vehicle-road on driving behavior and vehicle safety status in road traffic system, a simulated driving comparison test of six scenarios combined by multiple factors is designed.
39638 利用驾驶模拟器、生理仪、眼动仪分别采集驾驶行为相关的19项指标，选用方差分析比较各项驾驶行为指标差异情况。 Driving simulator, physiography and eye tracker are used to collect 19 indicators related to driving behavior respectively. The differences of sample data are compared by variance analysis.
39639 选用非线性支持向量机(Support VectorMachine，SVM)对样本数据进行分类及预测，建立了驾驶行为风险等级预测模型，并利用试验数据验证了模型的有效性。 The nonlinear SVM(support vector machine) is used to classify and predict the sample data. The driving behavior risk level prediction model is established, and the validity of the model is verified by the experimental data.
39640 结果表明：模型的预测精度达到93.94%，建立的风险等级预测模型能够有效的判别驾驶员及车辆的状态。 The results show that the prediction accuracy of the model reaches 93.94%. The established risk level prediction model can effectively judge the status of the driver and the vehicle.
39641 针对目前高速公路中央分隔带开口处活动护栏防撞等级较低的问题，提出了一种SAm级混凝土活动护栏及一种新型连接装置。 Aiming at the problem of low anti-collision grade of the movable guardrail at the opening of the central divding belt of the expressway, a SAm-level concrete movable guardrail and a new connecting device are proposed.
39642 基于有限元的方法，建立车辆与护栏的碰撞模型，通过LS-DYNA对车辆与护栏碰撞过程进行求解， Based on the finite element method, the collision model between the vehicle and the guardrail is established, and the collision process is also calculated by LS-DYNA.
39643 根据不同车型的碰撞结果分别在缓冲，阻挡和导向性能上对护栏的安全性能进行评价， According to the collision results of different vehicle types, the safety performance of the guardrail is evaluated in terms of cushioning, blocking and guiding performance.
39644 其中小型车辆与护栏碰撞后的OIV(Occupant Impact Velocity)值<12 m/s，ORA(Occupant Ridedown Acceleration)值<20 g且车辆没有驶出导向框； The OIV value is less than 12 m/s for small vehicles' collision with the guardrail, and the ORA value is less than 20 g and the vehicle does not drive out of the guide frame.
39645 大型车辆与护栏碰撞后没有发生穿越、骑跨等现象且车辆没有驶出导向框，均满足护栏安全性能评价标准。 No crossing or straddling occurred and the vehicle does not drive out of the guide frame after collision between the large vehicle and the guardrail.
