Singapore is well-known for being modern. Actually, the small metropolis state has been ranked essentially the most modern nation in Asia a number of occasions by the World Innovation Index. And now the nation is pushing new boundaries by testing out a monitor that glows at midnight as a way to enhance security and visibility at night time.
Located at Choa Chu Kang Road and Upper Bukit Timah Road, the 400m track, known as the Rail Corridor, is split up into four sections containing various different surface materials: fine gravel; grass and gravel; earth-colored porous concrete; and natural non-toxic light green strontium aluminate minerals. The last of these absorbs UV light during the day, allowing the path to emit a soft glow at night. The different surface materials are currently being tested to determine which one is the most popular, and the public is being invited to try out the track and provide feedback about the project.
