【摘要】 为满足高速公路运行车速与线形设计之间的协调性,提高高速公路车辆运行的安全性,开展高速公路设计一致性评价研究.在收集实际高速公路线形及事故数据的基础上,应用交互式道路安全设计模型(IHSDM)进行设计一致性评价,将评价结果与实际事故数据进行对比,分析了该模型的适用性.针对该模型在中国高速公路应用中存在的不足进行了改进,并将设计一致性存在问题路段与线形设计存在不足路段进行对比分析,验证了改进模型的有效性.分析结果表明:改进模型评价结果准确率为83.3%,较原模型评价准确率提高了25%,研究成果可以为高速公路线形设计的安全性评价提供技术支持.更多还原

【Abstract】 In order to meet the coordination between the speed of the highway and the linear design of the highway, improve the safety of the vehicles running on the highway and carry out a research on the evaluation of the consistency of the highway design, the interactive road safety design model(IHSDM) is used to evaluate design consistency based on the collection of actual highway alignment and accident data, the evaluation results is compared with actual accident data, and the applicability of the model is analyzed. Based on the deficiency of the model in the application of China expressways, a comparative analysis of the sections with problems in design consistency and the sections with linear designs is performed to verify the effectiveness of the improved model. The analysis results show that the evaluation accuracy of the improved model is 83.3%, which is 25% higher than the original model evaluation accuracy. The research results can provide technical support for the safety evaluation of highway alignment design.更多还原
