Traffic operation situation awareness method, module and system

The invention provides a traffic operation situation sensing method, module and system, which are applied to an intelligent road information physical system. The traffic operation situation sensing method comprises the following steps: monitoring traffic flow data of a management and control road network, and calculating a weighted density and a weighted flow corresponding to the management and control road network based on the traffic flow data, wherein the traffic flow data comprises vehicle flow and vehicle density of each road section of the control road network; obtaining a road network macroscopic basic diagram corresponding to the management and control road network, wherein the road network macroscopic basic diagram comprises an unblocked interval, a saturated interval and a supersaturated interval; and determining the traffic operation situation of the management and control road network based on the position interval of the weighted density and the weighted flow in the road network macroscopic basic
