Disclosed is a vehicle-road collaborative lane-changing risk assessment method based on a coordinate transformation, including: parsing vehicle marshaling information of a vehicle-road collaborative platform to obtain driving data of involved vehicles; determining a two-dimensional coordinate system that takes a lane-changing vehicle as a center point; converting a geographic coordinate system into a spatial coordinate system, and mapping the same into the two-dimensional coordinate system to complete the transformation from the geographic coordinate system to a real-time plane coordinate system; establishing a risk assessment model; inputting driving data and expected values of the involved vehicles during the lane changing into the risk assessment model for computational analysis and simulation; and exploring an influence of the driving data on a lane-changing risk to identify a factor that has a greatest influence on the lane-changing risk.
