The invention relates to the field of urban
safety risk management and control, and discloses an urban safety regional risk
analysis method and
system. The method comprises the following steps: acquiring video data of a crowd activity region by
video monitoring equipment; acquiring block port data of each main entrance of a region; counting and calculating the
traffic flow of a block port according to the block port data of the region, analyzing the proportion of vehicles to personnel entering the area, acquiring the data of vehicles remaining in the region, and carrying out early warning about regional
road congestion; analyzing video data of the crowd activity region based on a
video detection technology, and identifying crowd real-time statistics, density
estimation and regional dynamichuman flow abnormal characteristic analysis under multiple scenes in the region by adopting a depth learning
algorithm; and carrying out probability analysis and
verification by utilizing regional
pedestrian flow historical data, block port flow historical data, crowd real-time statistical data and the block port data of main entrances, calculating regional entrance
pedestrian flow and
traffic flow density, and carrying out early warning about regional
safety risk in advance. By the method, real-time sensing of human flow and
traffic flow in a key region is realized, and
safety risk early warning and prevention in the key region are also realized.
