Best Driver Fatigue Detection for Bus Operators
What is Driver Fatigue Detection?
Driver Fatigue Detection is an active safety technology that utilizes in-vehicle cameras and intelligent computer vision to monitor driver status in real-time and identify fatigue risks.
For long-distance passenger transport, tour bus, and public transit operators, drivers are required to maintain focus over long periods, especially during night trips and intercity routes where driver fatigue can significantly increase the risk of traffic accidents.
A DMS (Driver Monitoring System) uses a camera installed inside the cabin to capture images of the driver's face and head, analyzing the following behaviors:
1.Eye Closure: Detects prolonged eye closure and abnormal blinking patterns.
2.Yawning Detection: Identifies fatigue signs such as frequent yawning.
3.Head Pose Detection: Recognizes abnormal postures such as head dipping or nodding off.
4.Gaze Monitoring: Tracks line-of-sight shifts and distraction.
5.Phone Use Detection: Identifies dangerous behaviors such as using a phone while driving.
When the system detects abnormal behaviors, it can trigger in-cabin voice alerts and upload alarm events alongside relevant data to the fleet management platform.
Therefore, driver fatigue detection not only helps drivers become aware of fatigue risks in a timely manner, but also enables fleet managers to detect dangerous behaviors earlier and take corrective interventions.
Driver Fatigue is the Primary Factor in Passenger Bus Accidents
Fatigue driving and driver distraction are the major safety challenges facing passenger transportation. Passenger vehicles carry a large number of occupants, and any accident can lead to severe consequences.
According to 2024 traffic crash statistics released by the U.S. National Highway Traffic Safety Administration (NHTSA):
1.Total road traffic fatalities in the U.S. in 2024 reached 39,254.
2.Fatalities in crashes involving drowsy drivers totaled 644, accounting for 1.6% of total fatalities.
3.Fatalities in crashes involving distracted drivers totaled 3,208, accounting for 8.2% of total fatalities.
In Europe, survey data published by the European Transport Workers' Federation (ETF) in 2026 shows:
1.66% of surveyed bus and coach drivers reported regularly driving while fatigued.
2.One in four surveyed drivers reported having fallen asleep at the wheel while driving.
It should be noted that the above data represent accident statistics and driver self-reported surveys respectively, and cannot be directly equated to the exact proportion of passenger bus accidents caused by fatigue driving. However, they fully demonstrate the critical importance of driver fatigue management.
Traditional dashcams are primarily designed to record driving trips and generally cannot actively detect driver fatigue or distraction. For passenger transport operators, relying solely on manual inspections and post-event video reviews can no longer satisfy the active safety management requirements of modern fleets.
Features of Driver Monitoring System (DMS)
Y13: High-Definition Driver Monitoring Camera
When choosing driver fatigue detection equipment, image quality, night monitoring capabilities, installation flexibility, and compatibility with AI host units are all crucial considerations.
The Y13 (DSM-A720PS-Y13) is an HD camera designed for in-vehicle driver state monitoring applications, serving as the image acquisition device for DMS systems.
Y13 Detection Functions
1.Fatigue Driving Detection: Fatigue driving detection.
2.Smoking Detection: Smoking behavior detection.
3.Phone Call Detection: Making/receiving phone calls detection.
4.Distracted Driving Detection: Distracted driving detection.
5.Abnormal State Detection: Abnormal driver state detection.
Y13 Main Technical Specifications
Why Choose YUWEI Y13?
HD Image Capture: Features a 2-megapixel CMOS sensor to provide clear image inputs for driver status recognition.

Intelligent Fleet Management Solution for Passenger Transport
For large passenger transport enterprises, simply monitoring driver status is not enough. Companies also need real-time insight into vehicle positions, driving routes, interior conditions, and surrounding road risks.
The YUWEI Bus Fleet GPS Tracking Management System integrates DMS, ADAS, BSD, MDVR, GPS positioning, and a cloud management platform to deliver a comprehensive safety management solution for long-distance coaches, tour buses, and public transit vehicles.
Real-Time GPS Positioning & Route Tracking
Through GPS/BDS positioning and 4G communication, managers can:
1.View real-time vehicle locations.
2.Query historical driving tracks.
3.Monitor parking durations and operational status.
4.Set geofences.
5.Detect abnormal situations such as vehicle deviations from preset routes.
DMS Driver Status Monitoring
Utilizing in-vehicle DSM cameras, the system recognizes behaviors like fatigue, distraction, smoking, and phone usage. Working together with the onboard host, it enables local voice alerts, event logging, and remote uploads.
ADAS Forward Driving Assistance
Monitoring the road environment via a forward-facing camera, the system achieves the following functions based on system configuration:
1.Forward Collision Warning: Forward collision warning.
2.Lane Departure Warning: Lane departure warning.
3.Safe Following Distance Warning: Safe following distance warning.
4.Pedestrian Collision Warning: Pedestrian collision warning (depending on configuration).
While DMS primarily monitors the driver, ADAS focuses on the road ahead of the vehicle. Combining both provides more comprehensive active safety protection.
BSD Blind Spot Detection
Large buses are prone to visual blind spots during turns, lane changes, and reversing. The BSD system uses side-mounted cameras to monitor vehicles, pedestrians, and obstacles within specific blind spots, issuing alerts when risks are detected.
Multi-Channel Video Surveillance
By connecting cameras across the cabin, passenger area, doors, front/rear, and sides of the vehicle, multi-angle video monitoring is achieved.
Primary applications include:
1.Driver status monitoring.
2.Passenger area cabin monitoring.
3.Boarding and alighting door area monitoring.
4.Vehicle perimeter (front, rear, and sides) monitoring.
5.Historical video playback and event traceability.
Cloud Fleet Management Platform
Uploading vehicle video, positioning, and alarm data to the management platform via 4G/5G networks, the platform supports:
