The invention discloses a real-time road condition prediction method and system based on GPS data in a PEMS, and relates to the technical field of traffic control. According to the method, real-time road condition prediction is carried out by adopting GPS data (including latitude and longitude coordinates, speed, acceleration and the like) of vehicle-mounted exhaust gas detection equipment PEMS, a data source of an existing vehicle is fully utilized, the accuracy and the real-time performance of road condition prediction are improved, the method does not depend on specific sensor equipment, data acquisition is more convenient, and the cost is lower. Meanwhile, through the prediction model and feature selection, the complex incidence relation between the vehicle driving data can be better captured, and the accuracy and robustness of prediction are improved.
