Smart Traffic Fund drives safer trips Facing high population density and rising transport demand, the Government established the $1 billion Smart Traffic Fund to encourage research and development and drive innovations that enhance commuting convenience, maximise network efficiency and improve driving safety. A prime example is the Smart Ding Ding System, developed by Hong Kong Tramways over a period of more than a year with fund backing. The system utilises radio frequency identification (RFID) technology to boost operational efficiency and safety. Real-time precision "On each tram, we have installed an RFID reader on the roof," explained Hong Kong Tramways Assistant Manager (Technical Support) Chan Tsz-to. "We have also installed RFID tags at about 400 different locations across our network on the span wires. When a tram passes these tags, the system detects its actual location in real time." Before this system was installed, the company had relied on track switches to determine a tram’s location, a method limited by track configuration. Now, with precise real-time data, control room staff can better manage service intervals, handle unexpected disruptions and co-ordinate emergency manoeuvres. This operational upgrade also benefits the public. By combining real-time tracking with historical data, the company now provides estimated arrival times for the next three trams on its mobile application, allowing passengers to plan their journeys with ease. Furthermore, the system prioritises safety at the network’s 20 L-shaped curves. Special RFID tags have been installed at the curves to monitor tram speeds and ensure speeds remain within the safe limit of 8km per hour when taking a bend. "If the tram's speed is higher than the limit, an alarm is emitted by the system to alert the driver to slow down before entering the curve," Mr Chan added.
