OKI has begun the full-scale deployment of its 'Platform Fall Detection Support System' provided to railway operators. This system uses 3D LiDAR sensors (Note 1) to detect hazardous events in real time, such as falling from a station platform or getting caught in the gap between the platform and the train. It links with the signal equipment on the station platform to immediately notify train drivers, conductors, and station staff of any anomalies. This supports safety checks before departure and prevents hazardous events from being overlooked, contributing to securing safety on station platforms and saving labor and improving the efficiency of safety check operations.
Currently, OKI is collaborating with Meitetsu EI Engineer Co., Ltd. (Headquarters: Nagoya City, Aichi Prefecture, President: Naohiro Asano, hereinafter Meitetsu EI Engineer) to operate this system at three railway stations of Nagoya Railroad Co., Ltd. (Headquarters: Nagoya City, Aichi Prefecture, President: Hiroki Takasaki, hereinafter Nagoya Railroad).

According to the Traffic Safety White Paper published by the Cabinet Office, about 2,200 fall accidents from station platforms occurred in FY2022. While the introduction of movable platform doors (Note 2) as a preventive measure is progressing, implementation is limited to about 10% of all stations nationwide due to installation costs and location constraints. Under these circumstances, safety measures such as fall accident prevention are an urgent issue for railway operators. In addition, with the progressing labor shortage against the backdrop of a declining population, reducing the burden of safety confirmation and monitoring work by drivers, conductors, and station staff has also become an important issue.
This system adopts 3D LiDAR sensors, which are increasingly being utilized in autonomous driving cars, to detect people falling onto the tracks or getting caught in the gap between the station platform and the train with high accuracy and in real time through three-dimensional object detection and high-density laser data. Since the detection information is linked with the signal equipment on the station platform and immediately notified to drivers, conductors, and station staff, it is possible to prevent critical events from being overlooked and support safety assurance and safety confirmation operations on-site. Furthermore, since monitoring is possible regardless of whether a train is present or not, it is expected to be utilized for automating platform monitoring at unmanned stations and stations where labor-saving is progressing. Because this system consists only of a 3D LiDAR sensor and a control unit (server equipment), large-scale facilities are unnecessary, making it easy to introduce into existing station environments. OKI will continue to further promote the introduction of this system to railway operators nationwide, supporting safety measures on station platforms and the advancement of on-site operations.

Moving forward, OKI will continue to utilize its know-how regarding object detection technology and false detection suppression technology cultivated over many years to provide solutions that support the securing of safety on station platforms and the on-time operation of trains, contributing to the development of transportation infrastructure.

Glossary
Note 1: 3D LiDAR Sensor
LiDAR (Light Detection and Ranging) is a sensor that obtains distance and position from the reflected light of scanned lasers. By bundling multiple lasers, it measures as a three-dimensional space (3D). Because it can perform three-dimensional object detection, it can detect with higher accuracy than 2D LiDAR sensors.
Note 2: Movable Platform Door
Movable doors and fences that physically shield the area between the station platform and the tracks to prevent fall accidents.
