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。
According to the driver’s ability of information processing in the field of visual acuity and field of vision, a model for calculating the speed limit of road sections in highway traffic accidents is established. Based on the scene information of road and environment, traffic flow, traffic management, drivers and other personnel as well as the weather and other accident sites, ergonomics was used to quantify the probability of occurrence of various types of information and calculate from the basic information features of the accident scene The Speed Limit of Typical Expressway Traffic Accidents. The calculation results show that the limit of one-lane closed road section of two-way four-lane expressway is 70km.h-1; the limit of single-lane and two-lane enclosed road sections of two-way six-lane expressway are 806,0 km.h- 1; the speed limits of single-track, double-lane and three-lane closed road sections of bidirectional eight-lane expressways are respectively 80,706,0 km.h -1.
