摘要
为了对山区公路路段进行安全评价,以运行车速和行车轨迹偏移量为评价指标,提出了基于驾驶模拟器的安全评价方法。为了验证该方法的有效性,选取山区路段进行了实测实验,与基于驾驶模拟器的评价结果进行对比。结果显示2种情况下运行车速和行车轨迹偏移量差异性不显著,表现出相似的变化趋势,且评价得出的危险路段一致,表明了基于驾驶模拟器的安全评价方法的可靠性。
Due to the high frequency of accidents in mountain areas,road safety evaluation based on driving simulator was put forward to assess the road safety of mountainous highway with the indexes of vehicle speed and deviation of traveling trajectory.To verify the feasibility of the proposed method,field test was conducted on a mountainous highway and the results were compared with those derived from the simulated experiment.Results show that the variation trends of vehicle speeds and trails were consistent and their differences were small,which indicats that the driving simulator is effective to be used in the safety evaluation of mountainous highway.
