We refer to recent letters on the EMAS system by Mr Tan Poh Lam, “Is upgrading EMAS signs on expressways really necessary?”.
Since 1998, the Expressway Monitoring and Advisory System (EMAS) has been an effective integrated incident management system on Singapore’s expressway network. Through a network of electronic signboards, EMAS informs motorists of any traffic situation or incidents in real time while they are on the roads. These signboards are located along the expressways and before the entrance to the expressways, so that motorists can make a decision on whether to continue to use the expressway or to use an alternative route in the event of any traffic incidents. Many motorists have highlighted to us the usefulness of the EMAS signboards for them to make an informed travel decision while they are on the roads.
The EMAS signboards are regularly serviced every two months, and checked frequently by staff and contractors in their drive along the expressways to ensure integrity and quality of the message displays. Should any faults develop, our maintenance contractors are on standby to attend to any equipment fault. Members of public who notice a fault can also assist to alert us through our 1800-CALL-LTA hotline or through the Snap and Send feature under MyTransport.SG mobile application.
With the EMAS in operation for more than a decade, the system is nearing the end of its shelf life. Hence, we will need to upgrade the system, so that motorists can continue to make good use of the system. We are also taking the opportunity to put in new features to further enhance motorists experience. The upgraded signboards will have more space to display messages, and messages can be displayed in up to seven colours (green, red, blue, cyan, purple, yellow and white) for better readability.
We thank the readers for their feedback.
