The invention discloses a traffic transportation operation monitoring early warning and decision
analysis method based on vehicle infrastructure cooperation, and relates to the technical field of intelligent traffic. According to the method, real-time collection of dynamic traffic elements is realized through a multi-dimensional sensing network of a vehicle end, a road side and an environment and V2X communication, time-space reference unification of multi-
source data is ensured, a road-vehicle-environment-event
semantic network is constructed, multi-dimensional recognition of abnormal events such as accidents, congestion and
severe weather is realized in combination with hierarchical
feature extraction, and the method has the advantages of being high in practicability and high in practicability. The method is advantaged in that identification accuracy is improved, abnormal
event propagation paths can be predicted, global road network situation prediction capability is realized, differential early warning is generated based on a comprehensive
risk index, multi-level responses such as
traffic signal adjustment and path planning are triggered,
response time is greatly shortened,
emergency response efficiency is optimized, a decision execution effect real-time feedback mechanism is established, and the method is suitable for popularization and application. The
system performance is continuously optimized along with data accumulation, and the defect that a
big data platform lacks an
intelligent decision closed loop is avoided.
