Adopted from Japan, the 3D markings are intended to encourage motorists to reduce their speed because of the perceived narrower lane width.

The country’s Land Transport Authority (LTA) will introduce the markings to the Whampoa Drive Silver Zone at the end of this month.

The trial is part of the Silver Zone scheme, first announced in 2014, which was found to reduce accident rates by almost 75%. LTA has completed 15 Silver Zones and there are ongoing works for another ten. Other road safety features that are localised to each Silver Zone include chicanes, pinch points with ramp-downs, roundabouts, raised junctions, centre dividers, additional crossings etc.

LTA implements senior-friendly road safety features at areas with a high proportion of senior residents and senior amenities such as medical establishments.
