How Do Traffic Police Determine Fatigue Driving?
2 Answers
Generally, a simple method for detecting fatigue driving in vehicles is by calculating the continuous driving time. Once it exceeds the preset duration in the system, an alarm will be triggered. Below is an introduction to the common fatigue monitoring systems equipped in vehicles: Definition: The commonly equipped fatigue monitoring system is known as the Fatigue Driving Warning System (BAWS). It is based on the driver's physiological image response, consisting of two main modules: the ECU and a camera. By utilizing the driver's facial features, eye signals, head movements, etc., it infers the driver's fatigue state and provides alarm prompts along with taking corresponding measures. This system offers active and intelligent safety protection for drivers and passengers. Function: Some fatigue monitoring systems in vehicles are referred to as the Fatigue Recognition System. It records the driver's operational behavior from the start of the journey and can determine the driver's fatigue level by identifying changes in driving operations during long trips. A decrease in the frequency of steering operations by the driver, accompanied by slight but abrupt steering actions to maintain the driving direction, is a typical indication of the driver's lack of concentration.
During long-distance drives, I've noticed how traffic police check for fatigue driving. I heard they mainly rely on data from vehicle recorders to see if continuous driving exceeds 4 hours, or observe abnormal behaviors like drivers yawning or slow reactions. They set up checkpoints on the road, and when stopping vehicles, they ask drivers to perform simple tests, such as closing their eyes. Some officers use AI cameras to analyze facial fatigue features, and if risks are detected, they provide on-the-spot education or fines. As an ordinary driver, I recommend stopping to rest every 2 hours, eating something to stay alert, and not pushing through fatigue, as it can easily lead to loss of control and accidents. Regularly checking your vehicle's condition also helps ensure safe driving and avoids sudden issues. In short, traffic police base their judgments on evidence to prevent accidents, and following the rules benefits everyone.
