摘　　要：根据驾驶人在动视力和视野范围内的信息处理能力,建立了高速公路交通事故现场路段限速值计算模型。根据道路与环境、交通流、交通管理、驾驶人与其他人员以及天气等事故现场信息,运用人机工程学原理,将各类信息的出现概率进行量化处理,并由事故现场基本信息特征计算得到典型高速公路交通事故现场的限速值。计算结果表明:双向四车道高速公路单车道封闭现场路段限速值为70 km.h-1;双向六车道高速公路单车道、双车道封闭现场路段限速值分别为806、0 km.h-1;双向八车道高速公路单车道、双车道、三车道封闭现场路段限速值分别为80、706、0 km.h-1。Based on the ability of processing information within the dynamic sights and visual fields of drivers, a calculation model of speed-limit value for traffic accident scene section was set up. According to the information characteristics of road and environment, traffic flow, traffic management, drivers, irrelevant personnel and weather, the occurrence probabilities of different informations were quantitated by using ergonomics theory. The speed-limit values were calculated in typical freeway accident scenes referring to the information characteristics. Calculation result shows that the speed-limit value is 70 km ·h^-1 in one-lane enclosed accident scene of bidirectional four-lane freeway. In one-lane and two-lane enclosed accident scenes of bidirectional six-lane freeway, the values are 80, 60 km·h^-1 respectively. In one-lane, two-lane and three-lane enclosed accident scenes of bidirectional eight-lane freeway, the values are 80, 70 and 60 km·h^-1 respectively. 4 tabs, 2 figs, 14 refs.
