The invention discloses an expressway shunting area lane changing behavior risk prediction method and system, and the method specifically comprises the steps: constructing a vehicle lane changing intention process trajectory data set and a vehicle lane changing behavior process trajectory data set based on the start time of a lane changing behavior; constructing a lane changing intention recognition model by adopting a deep learning algorithm, and comparing to obtain a lane changing intention time period with the highest recognition accuracy; constructing a vehicle lane change collision probability index and a vehicle lane change collision severity index, and coupling a lane change behavior safety risk prediction index; a deep learning algorithm is adopted to construct a highway shunting area lane changing behavior safety risk prediction model, and lane changing behavior risk real-time prediction is performed based on the model. According to the method, the safety risk of the lane changing behavior of the vehicle in the expressway diversion area is predicted, the lane changing safety of the vehicle is guaranteed, and the method has important significance for dynamically predicting the traffic safety risk of the expressway diversion area, improving the expressway traffic safety management and control level and effectively reducing the traffic accident number of the expressway diversion area.
