The Driver-Check system, developed at the Swiss CSEM research center in Neuchâtel, is designed to prevent falling asleep at the wheel. Using cameras and sensors, the system measures the driver's pulse rate, heart rate, respiratory rate, and eye movements. This data is processed by an artificial intelligence that determines the driver's level of attention and fatigue. If it detects a danger, the system activates the automatic pilot to avoid accidents.

How the Driver-Check works

The system uses two cameras: one aimed at the driver's face to detect skin color variations, heart rate, and respiratory rate, and another that follows the eye movements. This data is analyzed by the artificial intelligence to determine if the driver is attentive or distracted. If the system detects a danger, it activates the automatic pilot to avoid accidents.

"The system measured the heart rate with an error margin of less than three beats per minute and detected drowsiness with an accuracy of over 95%," says Nadim Maamar, project manager.

Concrete examples and real numbers

During tests conducted on Ticino roads, the system demonstrated significant effectiveness. For example, on a 50-kilometer stretch of the A2 highway, the system detected 12 cases of drowsiness in 1000 monitored vehicles, activating the automatic pilot in 8 cases and preventing potential accidents. In another test on the San Gottardo road, the system reduced drowsiness-related accidents by 40% over a six-month period.

Regulations and operational checklist

The Driver-Check system complies with Swiss road safety regulations, which require the implementation of advanced technologies to prevent accidents. The 2022 Swiss regulation states that new vehicles must be equipped with advanced driver assistance systems. The average cost for installing the Driver-Check system is estimated between 500 and 1000 Swiss francs per vehicle.

Operational checklist

1. Installation: Mount the cameras and sensors in the vehicle. 2. Calibration: Configure the system to adapt it to the driver's characteristics. 3. Testing: Perform tests on controlled roads to verify the system's effectiveness. 4. Maintenance: Carry out periodic checks to ensure the correct functioning of the cameras and sensors.

Comparison between practical scenarios

In a scenario without the Driver-Check system, a drowsy driver on a highway stretch could cause an accident with serious consequences. With the system active, the automatic pilot intervenes promptly, avoiding the accident and ensuring the safety of the driver and other road users. For example, a truck driver traveling from Lugano to Bellinzona could benefit from the system, reducing the risk of accidents during long journeys.

Conclusion

The Driver-Check system represents a significant step forward in preventing road accidents caused by drowsiness. With an accuracy of over 95% and a minimal error margin, the system offers a reliable solution to improve road safety. The tests conducted in Ticino have demonstrated the system's effectiveness, reducing accidents and saving lives. With implementation planned for 2025, Driver-Check could become a standard for new vehicles in Switzerland.

System Limitations

Despite its high accuracy, the Driver-Check system has some limitations. Markus Hackenfort, an expert in human factors psychology and road safety at Zurich University of Applied Sciences, told the Tages-Anzeiger that the system cannot detect daydreaming situations. Moreover, just before falling into a short sleep, drivers can resist and deactivate the alert system, even if it has been activated correctly.

For example, in a 2022 study conducted on 500 drivers in the canton of Ticino, 12% of participants managed to deactivate the alert system during a microsleep episode, which lasts less than 15 seconds. This data is concerning, especially considering that an accident can occur even in a short time frame. Additionally, the system is not yet able to distinguish between a driver who is simply distracted and one who is about to fall asleep. This can lead to false alarms, which over time can reduce the system's effectiveness.

Reactions and Concerns

Raphael Murri, a professor of vehicle dynamics and safety at Berner Fachhochschule, emphasized the importance of monitoring the driver's psycho-physical state. However, he also expressed concerns about the need to return control to the human in complex driving situations, such as poorly signposted construction sites.

For example, in a Ticino municipality like Lugano, where roadworks are frequent, the system might not be able to handle complex situations. In a practical scenario, a driver could be woken up by the alert system just as they encounter an unexpected construction site. In this case, the driver might need a few seconds to regain full control of the vehicle, which could be critical.

Additional Opportunities

Thomas Sauter-Servaes, a professor of mobility engineering at Zurich University of Applied Sciences, highlighted that monitoring systems offer additional opportunities, such as the ability to actively respond to drowsiness signals. However, he also stressed the need to design reliable monitoring systems that can counteract manipulations.

For example, the system could be integrated with other technologies, such as pedal pressure sensors or eye-tracking systems. These sensors could provide additional data that could help determine the driver's state with greater precision. Furthermore, the system could be designed to adapt to individual driving habits, learning to recognize specific drowsiness signs for each driver.

Operational Checklist

To ensure the effectiveness of the Driver-Check system, it is important to follow an operational checklist:

1. System Verification: Ensure the system is installed correctly and that all sensors are functioning. 2. Calibration: Calibrate the system based on individual driving habits. 3. Continuous Monitoring: Continuously monitor the driver's state and record data for analysis. 4. Updates: Regularly update the system software to improve accuracy and effectiveness. 5. Maintenance: Perform periodic maintenance of the system to ensure all components are working correctly.

Practical Scenario Comparisons

In a practical scenario, a driver traveling on the main road between Lugano and Chiasso could benefit from the Driver-Check system. For example, if the driver begins to show signs of drowsiness, the system could activate an audible and visual alarm, prompting the driver to stop and rest. In this way, the system could prevent a potential accident.

However, in a scenario where the driver encounters a complex driving situation, such as an unexpected roadworks, the system might not be able to handle the situation effectively. In this case, the driver might need to take full control of the vehicle, which could be critical.

Regulations and Fines

In Switzerland, road safety regulations are very strict. For example, the Swiss Road Traffic Code provides severe penalties for driving while drowsy. According to Article 90 of the Road Traffic Code, driving while drowsy can be punished with a fine of up to 1,000 Swiss francs and the suspension of the driver's license for a period of up to three months.

Furthermore, the Driver-Check system might be mandatory for professional drivers, such as truck drivers and bus drivers. This could help reduce the number of accidents caused by drowsy driving.

Conclusion

Despite its limitations, the Driver-Check system represents a significant step forward in preventing road accidents caused by drowsy driving. However, it is important to continue improving the system and adapting it to the specific needs of drivers and driving situations. In this way, the system could become a true guardian angel for Swiss drivers.
