摘要
A driving risk unified quantification method based on comprehensive consideration of human, vehicle and road factors. The method comprises: obtaining an initial driving safety field model of a driving risk according to an energy transfer principle; decomposing the initial driving safety field model into a longitudinal direction and a transverse direction, and establishing a unified driving safety field model according to information of a vehicle j and traffic environment information; calculating a field force Fji caused by the vehicle j to any position point i in a traffic environment where the vehicle j is located; and according to the field force Fji, identifying the driving risk to which the point i is exposed under the influence of the vehicle j. According to the method, on the basis of the fact that a driving risk comes from comprehensive interaction between various factors that influence driving safety, a unified driving safety field modeling idea which can accurately reflect an interaction relationship between vehicles in a road traffic environment is provided.
