摘　　要：为提高危化品道路运输驾驶员日常安全绩效考核的科学性与便捷性,首先,从车载全球定位系统(GPS)中挖掘自然驾驶数据,运用改进的基于坐标系自适应变换的行驶轨迹分段拟合方法,提取行驶速度、加速度、平面曲率、道路坡度与坡长等动态驾驶数据;然后,结合车辆侧翻车速预测模型、长大下坡制动鼓温升模型,建立行驶速度稳定性、车辆横向稳定性、长大下坡制动稳定性和驾驶状态稳定性4个层次共7个指标的安全评价体系;最后,采用组合赋权法,构建10分制的危化品道路运输驾驶员安全绩效评价模型。研究结果表明:基于坐标系自适应变换的行驶轨迹分段拟合方法平均减少19.23%的拟合残差,构建的评价模型对危险驾驶行为反应灵敏。In order to improve science and convenience of daily safety performance evaluation of drivers in road transportation of dangerous chemicals,firstly,natural driving data were mined from vehicle GPS to evaluate drivers ’ safety performance.By using improved piecewise fitting method based on adaptive transformation of coordinate system,dynamic driving data such as driving speed,acceleration,plane curvature,road slope and slope length were extracted.Then,combined with vehicle rollover speed prediction model and brake drum temperature rise model,a safety evaluation system with seven indexes was established,which includes four levels:driving speed stability,vehicle lateral stability,braking stability and driving state stability.Finally,combination weighting method was used to build a 10 point safety performance evaluation model for road transport drivers of dangerous chemicals.The results show that piecewise-fitting method based on adaptive transformation of coordinate systemreduces fitting residual by19.23% on average,and evaluation model is sensitive to dangerous driving behavior.
