Electronic Road Pricing

This article is about a traffic management scheme in Singapore. For the more general concept about direct road user charges, see road pricing.

The Electronic Road Pricing (ERP) system is an electronic toll collection scheme adopted in Singapore to manage traffic by way of road pricing, and as a usage-based taxation mechanism to complement the purchase-based Certificate of Entitlement system. There are a total of 93 ERP gantries being built and located throughout the country, along expressways and roads leading towards the Central Area.[1] As of July 2024, only 19 ERP gantries are in operation and are all in expressways where congestion continues to be severe.[1][2]

The ERP was implemented by the Land Transport Authority (LTA) on April 1, 1998[3] to replace the preceding Singapore Area Licensing Scheme (ALS) that was first introduced on 11 August 1974 after successfully stress-testing the system with vehicles running at high speed. The system uses open road tolling; vehicles do not stop or slow down to pay tolls.[4][5]

Singapore was the first city in the world to implement an electronic road toll collection system for purposes of congestion pricing.[6] Its use has inspired other cities around the world in adopting a similar system, particularly London's Congestion Charge Zone (CCZ) and Stockholm's congestion tax.[7] It has also been proposed in New York City and San Francisco.
