摘要
利用实测数据,用回归分析方法建立了乘客不舒适感量化指数与车速、平整度标准差及路面状况指数的关系模型.根据计算结果,提出了高速公路对应不同路面状况的最高车速限制取值的建议.
A model to correlate passenger uncomfortableness index with vehicle speed, standard deviation of pavement roughness and pavement condition index (PCI) was derived by regression from observed data. Suggestions about maximum speed limits on freeways under different pavement conditions were presented based on the correlation.
