ERP is used to manage road congestion in Singapore. Drivers will incurERP charges when passing through ERP gantries during its operational hours. Toavoid incurring ERP charges, motorists can consider using alternative routes, travelling outside ERP operational hours, or taking public transport instead of driving.
ERP rates are reviewed every quarter and adjusted during the June and December school holidays, based on the traffic conditions at the time.
ERP rates are generally set in half-hour periods.
The time period (0730-0800) means the corresponding ERP rate applies from and including 7.30am and applies until but excluding 8.00am.
The same definition applies to other time periods.
ERP rates are adjusted to keep traffic moving at an optimal speed range of 20-30 kmh on arterial roads and 45-65 kmh on expressways.
The ERP charge you pay depends on:
- The type of your vehicle. Bigger vehicle types pay more.
- The time you enter the ERPgantry. During peak hours, charges can change every half hour to help spread traffic flow over a longer period.
