The invention provides a road traffic early warning system. The system comprises at least one group of conductive coils, data collectors and a traffic early warning center, wherein the at least one group of conductive coils is buried in at least one carriageway of each preset road section respectively; the data collectors are connected to each group of the conductive coils on each carriageway and are used for generating traffic data of the carriageway according to a current signal provided by each conductive coil group; the traffic early warning center is communicated with the data collectors and is used for determining a traffic jam condition based on traffic data analysis of the carriageway of received each road section and providing for a driver. The conductive coils are used to collect the traffic data and the data is transmitted to the traffic early warning center. A bandwidth occupied by video data transmission can be effectively reduced. Because the traffic data is directly provided, a process of traffic data extraction does not need to be performed on a video image so that a data processing amount of the early warning center is greatly simplified.
