The invention discloses an expressway vehicle lane change risk estimation method, a medium and equipment. The method comprises the following steps: determining a vehicle to be subjected to lane change in a target area; constructing a lane changing scene schematic diagram based on the position relationship between the vehicle to be subjected to lane changing and the adjacent vehicle; determining a lane changing danger stage of the vehicle to be subjected to lane changing according to the lane changing scene schematic diagram; constructing a lane changing risk estimation model based on the lane changing danger stage and a pre-configured lane changing minimum safety distance; the lane changing risk estimation model is used for determining the collision risk of the vehicle waiting for lane changing during lane changing, and the minimum lane changing safety distance is determined at least based on the lane changing danger stage. According to the method, the more accurate risk value of the vehicle on the expressway during lane changing can be estimated.
