The invention relates to a traffic safety risk monitoring method and device, a storage medium and computer equipment. The method comprises the following steps: acquiring driving data of a vehicle driving on a target road and traffic flow data of the target road within a preset acquisition duration; obtaining a total frequency index of dangerous driving behaviors according to the driving data; acquiring a traffic flow characteristic index according to the driving data and/or the traffic flow data; and obtaining the safety risk level of the target road based on a decision tree model according tothe total frequency index and the traffic flow characteristic index of the dangerous driving behaviors. According to the method, the driving data of the vehicle and the traffic flow data of the target road are comprehensively considered, traffic safety risk assessment and monitoring are carried out on the target road from multiple dimensions, the assessment dimensions are comprehensive, and the assessment precision is more accurate.
