New findings providing ways to reconstruct cycle/passenger car accidents through experimental determination of vehicle deformation energies.

A method has been developed that makes possible a more exact reconstruction of cycle/passenger car accidents by means of direct collision analysis. This initial study has been concentrated on simulation of the most common type of accidents, that at an intersection. The cycles and impact carriage crashed against the door areas of non-moving passenger cars or the barrier at right angles. Impact equations were derived and the method applied incorporating the test results.
