The Electronic Road Pricing system, installed in 1998, is another lever in our strategy to keep roads free-flowing at all times. It is a technological upgrade from its earlier incarnation as the Area Licensing Scheme which levies a flat fee on vehicles entering the Central Business District (CBD).
ERP gantries erected at roads prone to congestion use Radio Frequency Identification (RFID) technology to automatically collect a fee from any vehicle passing under them during their operating hours.
ERP rates are differentiated based on traffic conditions, and adjusted to keep traffic moving at an optimal speed range of 20-30 km/h on arterial roads and 45-65 km/h on expressways.
Next Generation ERP System
We are developing a more effective and responsive traffic management system which is less costly to build and maintain, more space-efficient and requires a shorter lead time to implement compared to the current gantry-based system.
The next generation ERP system uses Global Navigation Satellite Systems (GNSS) technology, a commonly used navigational technology today. With GNSS, we will be able to better collect aggregated traffic data, to help improve traffic management and transport planning. Motorists will also enjoy more value-added services, such as advance alerts on charging locations, real-time traffic information and road safety advisories.
