Electronic Road Pricing

What is ERP

Electronic Road Pricing (ERP) is an electronic system of road pricing based on a pay-as-you-use principle. It is designed to be a fair system as motorists are charged when they use the road during peak hours.

LTA reviews the traffic conditions on the expressways and roads, where the ERP system is in operation, on a quarterly basis and during the June and December school holidays.

After the review, the ERP rates would then be adjusted where necessary to minimise congestion on the roads. ERP has been effective in maintaining an optimal speed range of 45 to 65 km/h for expressways and 20 to 30 km/h for arterial roads.

How it works

The ERP system uses a dedicated short-range radio communication system to deduct ERP charges from CashCards. These are inserted in the In-vehicle Units (IUs) of vehicles before each journey.

Each time vehicles pass through a gantry when the system is in operation, the ERP charges will be automatically deducted.

 

Aim

The pay-as-you-use principle of ERP makes motorists more aware of the true cost of driving. This way, road usage can be optimised.

Charges are levied on a per-pass basis and rates are set based on traffic conditions at the pricing points.
A motorist is encouraged to decide whether to drive, when to drive and where to drive.
He may choose a different route, mode of transport, time of travel, or not travel at all.
Those who choose to pay and stay on the road will enjoy a smoother ride.

 

Benefits

Fair
Charges are based on usage so those who contribute more to the congestion pay more. Those who use the roads less frequently or who travel during non-ERP hours will pay less or not need to pay at all.
Convenient
Motorists need not purchase daily/monthly licences.

Reliable
As a fully automated system, there is no risk of human error as human enforcement is not required.

 

History

The first road pricing scheme, known as the Area Licensing Scheme (ALS), was introduced in the Restricted Zone (RZ) in 1975. The scheme was subsequently extended to major expressways with the Road Pricing Scheme (RPS).

In September 1998, the ERP system replaced the manual system for the RZ and expressways. In September 1999, ERP was extended to some of our key arterial roads beyond the RZ.

Graduated Electronic Road Pricing

Since February 2003, motorists have been enjoying savings of 25 cents to $2 when passing through most of the ERP gantries.

To discourage motorists from speeding up or slowing down to avoid paying higher ERP charges, the LTA decided to make ERP changes more gradual.

Graduated ERP rates have been introduced for the first five minutes of the time slot with a higher rate. If the next period has a lower ERP rate, the new rate is introduced for the last five minutes. This applies to cases where the change in the rate is at least $0.50, depending on vehicle type. For car drivers, the graduated ERP rate applies where the change in rate is at least $1.

Because the graduated rate is introduced in the more expensive band, it means overall lower ERP charges for motorists.

ERP Violations

Motorists who pass through an operational ERP gantry without a properly-inserted CashCard in the IU, or one with insufficient monetary value in the CashCard to pay the ERP charges, will receive a letter within a few days of the violation requesting them to pay the outstanding ERP charge plus an administrative fee of $10, within two weeks from the date of the letter. The administrative fee is reduced to $8 if payment is made electronically via the following channels:

LTA's One.Motoring website
AXS stations
Self-service Automated Machines (SAMs) at post offices
vPost
Automated teller machines
Telephone and internet banking services
