Road CCTV monitoring system and road CCTV monitoring method

The invention discloses a road CCTV monitoring system, which comprises a CCTV control module, a CCTV monitoring module, a video acquisition module, an analysis and computation module and a plurality of flow monitoring modules, wherein the flow monitoring modules acquire travel information data of vehicles running on roads and transmit the travel information data to the analysis and computation module in real time; and the analysis and computation module processes the travel information data and transmits the result of the processing to the CCTV control module. The invention also discloses a road CCTV monitoring method. In the method, the analysis and computation module compares the travel information data acquired in two adjacent time periods, and the system gives a road jam alarm according to the result of the comparison. The system and the method adopt the flow monitoring modules to monitor the travel information data of the vehicles running on the roads, grasp the travel conditions of the vehicles on the roads according to the change of the data, and give road jam prompt and determine the position of a road jam according to the travel conditions.
