The invention provides an expressway traffic accident detection and early warning system. The expressway traffic accident detection and early warning system comprises a field detection unit, a data processing unit, an information transmission unit and an alarm unit. The field detection unit comprises an image acquisition module and an image receiving module; the data processing unit comprises a vehicle detection module, an agglomerate fog detection module, a vehicle tracking module, an information processing module and a storage module; the vehicle detection module is used for detecting and judging whether a target object in a to-be-detected area is a vehicle or not; and the agglomerate fog detection module is used for detecting whether agglomerate fog exists in the to-be-detected area ornot; the information transmission unit comprises a wireless transmitting module; the wireless transmitting module is connected with the information processing module; and the information processing module is communicated with the alarm unit through the wireless transmitting module. Correspondingly, the invention provides an expressway traffic accident detection and early warning method, which is higher in detection precision and low in false alarm rate, and secondary traffic accidents on the expressway are effectively avoided.
