Your Speed Sign

'Your Speed Sign' is a live electronic device that displays the real time speed of vehicles and alerts motorists that they are speeding. It encourages motorists to obey the speed limit displayed and thus improve safety on the roads.

YSS is now part of LTA's range of measures used to improve the safety of roads along selected expressway slip roads. LTA observed that about 12% more motorists kept to the speed limit at the pilot locations. 72% of motorists surveyed also felt that the YSS is effective in helping them to adjust their driving speed while negotiating a bend along the slip road after exiting expressway.

YSS has been implemented at the following locations: LTA has extended its efforts in road safety even further by going 'green'. Solar-powered YSS were installed at PIE (Changi) exit to Tampines Ave 5 and BKE(PIE) exit to KJE(PIE) in 2011and 2014 respectively. Benefits from the use of solar-powered YSS include the omission of extensive trenching, less disruption to the site and shorter installation time. The solar-powered YSS is also eco-friendly as no electricity is needed.

As global energy demands increase, LTA aims to make effective use of energy and a wide range of 'green' technology applications can be expected.
