Recently, as part of ASV (Advanced Safety Vehicle) development, some manufacturers have been developing "drive recorders" that record data when accidents occur. If this data has been recorded, it can contribute to determining responsibility for the accident and to preventing similar accidents in the future, but there is a problem with the reproduction accuracy of the data. As a first step toward resolving this problem, we conducted a study of the reproduction accuracy of vehicle trajectories and vehicle speeds. Reproduction accuracy of trajectories is not uniform, due to the cumulative effects of error resulting from multiple factors, including the time of the reproduction, zero point drift, changes in vehicle orientation, and irregularities in the road surface. We therefore first used a simulation to compare theoretical trajectory calculations with trajectory calculations that incorporate measurement error for various parameters, and identified the theoretical error for vehicle trajectories.
