针对山区道路车辆行驶安全及潜在危险路段的辨识问题,在分析山区道路主要事故形态特征的基础上,从车辆动力学角度出发,基于风险分析理论,以车辆行驶过程中可能出现的侧翻、侧滑、侧向偏离、纵坡倒溜等事故特征为评价指标,建立了山区道路车辆运行安全评价模型,用风险指数来反映车辆在山区道路行驶时事故发生的可能性。通过对实际道路车辆行驶安全性评价表明,所建立的安全评价模型能定量计算车辆在实际道路行驶时的安全指数,并能分析道路全线的潜在风险情况,为山区道路与车辆之间的协同安全评价提供了一种有效方法。
Aiming at the identification of road safety and potential dangerous road segments in mountainous area, based on the analysis of the morphological characteristics of the main accidents in mountainous roads, from the perspective of vehicle dynamics, based on the risk analysis theory, Slip, lateral deviation, sloping slope and other accident characteristics as the evaluation index, established a mountain road vehicle safety evaluation model to use the risk index to reflect the vehicle when the mountain road driving accident possibility. The evaluation of driving safety on actual road vehicles shows that the safety evaluation model established can quantitatively calculate the safety index of vehicles on the actual road and can analyze the potential risks across the road to provide a coordinated safety measure between the mountain roads and vehicles Evaluation provides an effective method.
