The invention discloses a highway intelligent monitoring system and method. The method comprises the following steps: counting the number N1 of current vehicles and the average vehicle speed V1 in a highway with the length of L1; when V1lt; when Vmin1 is greater than Vmin1, estimating the average time T1 = L1/V1 when the current vehicle passes through the section of expressway; and according to the average time T1, carrying out regional speed limiting on the previous section of the expressway L2 of the expressway L1 as V2. According to the invention, a regional speed limiting device and a speed measuring device on an existing expressway are combined, and a vehicle counter is combined, so that the number and the average driving speed of vehicles in each expressway section are monitored in real time; for the monitored congested expressway section, the time for the vehicles to enter the congested road section is prolonged in a mode of performing speed-limiting driving on the vehicles in the upper expressway section, further vehicle upheaval is prevented, the average implementation speed of the vehicles in the congested expressway section is further reduced, and the driving speed of the vehicles in the congested expressway section is further improved. And the congestion time of the congested highway section is effectively shortened.
