According to one poll that was conducted by Huffington Post earlier this year 45% of Americans admitted that they had at one point in time felt so tired while driving, that they actually believed they might doze off. Drowsy driving is an underestimated accident factor in this country, and doesn't always get the kind of attention that it deserves. This is even though such drivers actually cause more than 100,000 accidents a year. More than 1,500 fatalities and more than 40,000 injuries are also linked to drowsy driving.
The auto industry has acknowledged the dangers that come from drowsy driving, and has been investing in technology to help prevent such risky driving behavior. As part of that new technology comes a new system of sensors. The system is designed to be embedded in the driver’s seat belt and seat. The sensors are designed to measure the person's breathing and heart rate as he is driving. When the person becomes sleepy or drowsy, his heartbeat and breathing rhythms tend to change, becoming slower and more relaxed. The system is designed to pick up on such changes in cardiac rhythm and breathing rates. When the system detects changes, it immediately issues an alert to the driver that he is at danger of dozing off.
There are currently other systems that help detect drowsy driving, by immediately detecting when the car is moving out of its lane. However, the seatbelt-sensor embedded system is designed to detect signs of drowsiness even before the car begins to veer from its lane. Therefore, it does a much better job of detecting drowsiness earlier, compared to the technologies that are currently in operation in several automobiles. The company that is developing the system is soon planning to conduct real -traffic tests.
