摘　　要：高速公路匝道处历来是交通事故多发区,选取影响高速公路匝道区行车风险的安全分析指标,采用加法评分法对高速公路匝道区车辆行车风险系数进行分析,提出高速公路匝道行车风险系数计算模型,应用统计学中的效用系数理论对模型的数值进行规范化处理,并对模型参数进行标定。The ramp of freeway has always been the accident-prone areas, and the paper selected index for the traffic safety analysis of freeway ramp, which influence the travelling vehicle on freeway ramp. Using average adder law to analyze the vehicle travelling risk on the freeway ramp, the paper proposed the calculating model of travelling vehicle risk on the freeway ramp. Applying the effectiveness factor theory of statistics to the value of model for standardized processing, the parameters of model is standardized.

关 键 词：高速公路 匝道 行驶风险 安全评价
