The Electronic Road Pricing system, installed in 1998, is another lever in our strategy to manage road traffic. An earlier incarnation of this was the Area Licensing Scheme which levied a flat fee on vehicles entering the Central Business District (CBD).
ERP gantries are erected at roads prone to congestion. They 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.
We are developing a more 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.
ERP 2.0 uses Global Navigation Satellite Systems (GNSS) technology. With GNSS, we will be able to better collect aggregated traffic data, to help improve traffic management and transport planning. Motorists will also have access to services, such as advance alerts on charging locations, real-time traffic information and road safety advisories.
