  • In accident analysis vehicle collision model based on the momentum conservation is solved by the inverse algorithm to calculate pre-crash speed accurately. Then post-crash speed is calculated by a kinematics formula with survey data from accident scene, and is used to calculate the pre-crash speed by the model. In this work, the pre-crash speed error emerges when examining the model calculation results by a car crash test. From the model solving and error propagation processes, the origin and solution of the pre-crash speed error was studied by the car crash test to improve the accuracy of traffic accident analysis. Firstly, the matrix theory was applied to study the origin of the pre-crash speed error. Secondly, the inverse iterative algorithm was applied to establish a solution of the pre-crash speed error. Finally, an example was used to verify the solution. Study results and example applications show that the error in post-crash speed calculation with the kinematics formula is the decisive to the pre-crash speed error. Thus, the pre-crash speed error can be eliminated completely by simply correcting the post-crash speed error.
