摘要： 从驾驶员安全舒适性角度对高速公路平曲线指标进行安全性评价具有现实意义，基于课题组的驾驶工作负荷理论、计算方法和安全舒适性阈值等研究成果，根据设计方案，现场随机抽取小客车和大货车典型试验驾驶员各14名进行驾驶安全舒适性试验.通过对339个平曲线段样本的驾驶工作负荷度变化规律分析，对平曲线段进行了驾驶安全舒适性界定；通过对平曲线指标与驾驶工作负荷度的相关性分析，建立了平曲线半径与驾驶工作负荷度关系模型；结合驾驶工作负荷度安全舒适性阈值，利用模型对平曲线指标进行安全舒适性评价；最后，通过对两条高速公路进行安全性评价分析.结果表明，该评价方法是可行的.

Abstract: In view of driver safety and comfort, safety evaluation of index of horizontal curve on freeway is significant to road design, operation and management. Based on the theory and method of driver workload, typical vehicles (cars and trucks) are chosen for realvehicle testing with a random sample of 28 drivers. This study analyzes the data of 339 horizontal curve sections. The orderliness of driver workload degree is obtained, by which the authors classified the standard of horizontal curve. It establishes the regression model between driver workload degree and road alignment index. Combined regression model with controlling values of driver safety, index of horizontal curve is used to evaluate driving safety. Finally, the case studies of two freeways show that the evaluation method is feasible.

Key words: traffic engineering, driver workload, horizontal curve, driver safety and comfort, safety evaluation
