The Expressway Monitoring and Advisory System (Chinese: 电子监控与信息系统), also known by its acronym of EMAS, is a computerised system that is used to monitor traffic on Singapore's expressways. EMAS enables Land Transport Authority (LTA) personnel to detect accidents and respond to them more quickly. In addition, it notifies motorists of adverse traffic conditions.[1]
