Effective method for rear-end collision warning system

The rear-end collision warning system is prone to give false positive warnings, which can interfere with the driver's concentration while driving, and very often, the high pitched warning sound used in these systems is found to be annoying, and drivers tend to turn the system function off. As a result, this research mainly focused on showing how human beings learn and behave unconsciously, and how a warning sound can be effective without being high pitched. This paper validates the effect of an inconspicuous alarm or warning sound, by testing on a driving simulator. The test subjects learned the false positive warning generation pattern also unconsciously, and they applied the brake quickly only in case of imminent danger.
