Abstract

The invention discloses an automatic driving open test road environment risk degree determination and grading method and system, relates to the technical field of road traffic safety risk assessment and management,. The method includes: constructing various types of accident risk degree calculation models according to historical artificial driving road accident data; correcting each type of accident risk degree calculation model according to the vehicle accident data, and calculating each type of accident risk degree by utilizing the corrected each type of accident risk degree calculation model according to the road environment data and the traffic flow data; and determining the safety risk degree of the road environment according to the risk degrees of various accidents. By considering the risk causes of various accidents, the scientific calculation of the risk of the automatic driving open test road environment is realized.
