Smart Driver Assistant for Automated People Mover (REF:C-0031)
E&M InnoPortal Trial Project Ref. No.:

Overview

The Signals Passed at Danger (SPAD) Alert Device is a smart driver assistant designed to enhance the safety of the Automated People Mover (APM) system at Hong Kong International Airport. By leveraging Artificial Intelligence (AI) and video analytics technologies, this portable device effectively detects improper driving behaviors, such as fatigue, yawning, or inattention, in real-time. It promptly alerts both the driver and the APM controller when dangerous situations arise, such as speeding, activation of the red signaling light or the presence of objects on the guideway. Additionally, the device securely encrypts and stores recorded videos, allowing for playback during incident investigations alongside guideway conditions, driver images and device records.

The implementation of this device effectively mitigates accidents caused by driver negligence. By providing early warnings to drivers regarding potential safety risks, it contributes to operational safety by reducing the frequency of accidents and minimising APM system downtime.

Problem Addressed

The problem addressed by this project is the lack of a versatile and all-in-one product for monitoring both driver's behaviors and trackside conditions simultaneously. The existing AI assistant for safe manual driving in the APM system faced limitations in detecting the trackside equipment and its status due to the dark environment in tunnel areas and the high train speed. While the objects can be identified, it remains difficult to provide the status of different trackside equipment.
Innovation

The SPAD Alert Device is a portable smart device incorporating edge computing, high-performance cameras and an advanced AI algorithm. This device significantly enhances object identification and status detection capabilities. With the help of edge computing technology, instant alerts can be sent to both the driver and the traffic controller whenever potential risks are detected.

The device provides the driver with real-time information about the status of trackside signals, the position of point machines and the clearance ahead on the track. Simultaneously, it reminds the driver to maintain focus on their driving tasks. Moreover, the device has been designed with versatility and portability in mind, making it easy to use across various APM systems. This innovative device represents the world's first AI-powered smart driver assistant for APM systems.
Key Benefits
  • It is a multipurpose and easy to use device that can detect not just train operator's fatigue level and inattention, but also operators' improper behaviors during manual operations, such as using mobile phones
  • monitor the status of the tunnel in front of the train and give out warnings for incorrect signal light status, point position, and presence of obstacles along the tunnel
