The invention provides a traffic early warning method and device of a population movement track. The traffic early warning method comprises the following steps: acquiring telecommunication data of a mobile terminal to obtain longitude and latitude data of three target base stations; calculating distances among the mobile terminal and the three target base stations, and mutual distances among the three target base stations, so as to determine a current position of the mobile terminal; and pre-estimating a future moving position of the mobile terminal according to position information records of the mobile terminal, so as to judge the population density in a monitoring region at a certain moment in the future according to the pre-estimated future moving position of the mobile terminal, and carry out traffic early warning of the population movement track of the monitoring region. According to the method provided by the invention, the cost of early warning of the population density is effectively reduced and the complexity of calculating the population density is reduced; and meanwhile, the change condition of the population density in the monitoring region is obtained according to the moving track pre-estimated by the position data of the mobile terminal, and identification and early warning services can be provided for a population traffic jam condition; and the accuracy of predicating the traffic can be effectively improved.
