The invention relates to the technical field of traffic accident information processing, in particular to a driving speed analysis method in a vehicle collision accident, which comprises the following steps of: constructing a hypothesis model, constructing classified statistical data into a matrix based on a statistical method, and performing data analysis by using a principal component analysis method and the like. And comprehensive indexes and factors having significant correlation with the vehicle speed are analyzed, data modeling is performed based on a data set sample formed by cases, and a theoretical relationship between the driving speed of the car and the damaged trace of the car is constructed. And checking and evaluating the model, observing and checking whether the built theoretical model can accurately reproduce the dynamic development track between the driving speed of the car and the damaged trace of the car, comparing with a known result, and checking and correcting the built theoretical model. The identification method and technology are optimized, and the road traffic accident identification process, method and technology under specific conditions are optimized by completing verification and evaluation of the model and relying on the established theoretical relation between the car driving speed and the damaged trace.
