The invention discloses an intersection traffic jam preventing and automatic emergency handling system. The system is characterized by comprising an image capturing unit, an image analysis unit, a network cloud data and cloud computing unit and a signal lamp control computer, wherein the image capturing unit is used for acquiring intersection video images, the image analysis unit is used for analyzing the intersection video images so as to discover traffic jam in a specific direction of an intersection, the network cloud data and cloud computing unit is used for acquiring traffic jam states of peripheral intersections of jammed intersection nodes and judging whether jam in the current intersection can be eased by peripheral road networks in short time or not, and the signal lamp control computer is used for generating corresponding signal lamp phase tables according to judgment results of the network cloud data and cloud computing unit and allocating the signal lamp phase tables to an intersection signal lamp control machine. The intersection traffic jam preventing and automatic emergency handling system aims to enable a computer system to discover the traffic jam states automatically before the traffic jam turns into a 'deadlock' really, and ease intersection vehicle jam states to the utmost by modifying a traffic signal lamp phase time sequence and the like so as to avoid intersection traffic 'deadlock' as far as possible. Meanwhile, the intersection traffic jam preventing and automatic emergency handling system is capable of warning automatically when the intersection traffic 'deadlock' occurs really, publishing warning information and controlling an influence range by adopting extreme signal lamp phases.
