Kobe University trials LEDs on Indonesian metro

LED indicators have been deployed on construction sites for the Jakarta metro system.

Workforces with low literacy rates cannot rely on signage to communicate risks on construction sites. Kobe University researchers think an LED “traffic light” system could be the answer.

On-Site Visualization (OSV) uses real-time data processing through sensors attached to walls and pillars that measure tilts and problems in the structure.

The information feeds through to different coloured LEDs. 

A blue LED means there are no irregularities, yellow and red indicate there is a danger the building will collapse.

The LEDs were trialled on the Jakarta metro project with support from the Japan International Cooperation Agency.

Two inner city metro stations and one elevated station used the technology, which was overseen by researcher professor Sinichi Akutagawa from Kobe University Graduate School of Engineering.

“I want to build a human network that combines know-how from different fields to improve levels of safety and security” said Akutagawa.
