We thank Mr Yeo Thye Lye for his suggestion “Reduce expressway lighting” (The Straits Times, 15 Aug).
Mr Yeo’s suggestion to remove one in two lamp posts from our expressways may inadvertently make our roads less safe for motorists. Doing so may result in patterns of dark and bright patches on the roads, causing a visual strain and posing a safety risk for drivers.
Our street lighting design complies with international standards to ensure our roads are sufficiently lit for safe travel. We also continue to study new technological solutions for more energy efficient lighting systems, by reducing life cycle cost while achieving the required lighting standards.
Since July 2014, we have been progressively replacing street lights with more energy efficient LED lighting at about 500 lower-trafficked roads island-wide. We are now actively looking into the possibility of using LED technology along major arterial roads and expressways. We have started a trial to evaluate if high wattage LED lamps can be a more energy efficient alternative to light up our expressways.
