Most of expensive cars has systems that monitors driving and alerts in risky and unsafe situations. These systems are not integrated in older or less pricey vehicles. Spain’s University of Alcalá developed the app called DriveSafe that comes to help. It requires users to mount their smartphone in front of the windshield.
The app uses smartphone’s accelerometer, GPS, and rear camera to monitor acceleration, braking, position within the lane, the manner in which the driver approaches other vehicles from behind, driving speed compared to the speed limit taken from online map services. It also provides real-time alerts in audio-visual format when it determines that unsafe driving is occurring. All videos are recorded with attached map locations of those moments, which can be viewed afterwards.
