摘　　要：为了解决出入口匝道安全性问题,减少高速公路出入口匝道事故率,通过对高速公路出入口匝道安全现状进行分析,从道路因素、车辆因素以及其他因素方面选取9个评价指标分析高速公路出入口匝道的安全状况,应用集值统计法确定各个指标的权重,通过对出入口匝道设计参数的分析,评价高速公路出入口匝道的安全性。应用建立的出入口匝道安全评价模型对仁赤高速公路某典型的出口匝道进行了详细的安全评价。In order to solve the security problems and reduce the accident rate on the freeway entrance and exit ramp, by analyzing the safety current situation of the freeway entrance and exit ramp, nine evaluation indexes is chosen to analyse the security status on the freeway entrance and exit ramp from road factor, vehicle factor and other factors. The set valued statistics is applied for confirming the weigh of each index and the security of the freeway entrance and exit ramp is evaluated by analyzing the design parameter on the entrance and exit ramp. The security evaluation model of the entrance and exit ramp established on this essay is applied for the detailed safety evaluation on the one of the typical exit ramp in the RenChi freeway.
