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.

Description

technical field [0001] The invention relates to the technical field of road traffic safety risk assessment and management, in particular to a method and system for determining and grading the risk degree of the road environment for an open test of automatic driving. Background technique [0002] At present, the vigorous development of artificial intelligence, big data, communication technology, etc. has made a high degree of progress in autonomous vehicle technology. Open road testing is an indispensable and important link in the development and application of autonomous driving technology. In order to enable vehicles to operate safely, reliably, and efficiently under various road traffic conditions and usage scenarios, the autonomous driving function requires a large number of tests and verifications and undergoes a complex evolution process. Before self-driving cars are officially launched on the market, they must be fully tested in a real traffic environment to fully ver...
